MONUMENT

With his explanations to the reporters completed, Dr. King felt that when he pulled the switch he would automatically restore his good name and bring to a close a career of solid scientific achievement. Most of all, he would bring to an end the practice of referring to him as "Side Effect Charlie."

Dr. Charles King was willing to admit that there were excellent reasons for his acquiring this hated nickname. The facts were that the bulk of his scientific achievements were made inadvertently--that is to say, his discoveries were all made through investigation of unexpected side effects of his experiments. In a career conspicuous for unusual, unanticipated side effects, two in particular stand out.

The first discovery resulted in rendering the entire heat-oriented metallurgical industry obsolete, and founding upon its corpse a new industry. This was based on the extracting of metal from ore and its subsequent shaping by first eliminating the bonds that hold the molecules of metal together, and then reversing the process when the desired shape was attained. Dr. King did not discover this process directly. He thought he had discovered a method of making metal surfaces self-lubricating and 100% friction free. It was not until several installations utilizing his lubrication method became pools of liquid metal that Dr. King bothered to discover how his method worked, and of course the means to reverse his process. The resulting revolution in metal-processing methods endeared him to everyone--except a few vested interests like the shareholders in existing metal companies, who were uniformly glum.

The second discovery, although monumental in itself, is important because it indirectly led to the special project which Dr. King was just completing. Dr. King succeeded in growing some crystals in a nutrient solution. What actually happened was that while eating lunch at a lab table he managed to knock something into something else and a crystal developed. Dr. King became fascinated with the odd structure of these crystals as revealed to him under an electron microscope. As a result, he took to investigating the properties of the crystals whenever he could find time. Despite his well earned reputation as an accidental discoverer, it should be pointed out that Dr. King is a very methodical man. This means he is capable of repeating the same mistake twice, or for that matter any number of times. Therefore, Dr. King produced all the crystals he needed.

It was during a vacation in the Adirondacks that Dr. King discovered the propulsive qualities of the crystals.

This discovery, of course, is what led to the perfection of the "King Propulsor Unit," the heart of our starship drive systems. Dr. King was investigating the piezo-electric properties of the crystals in a makeshift device of his own design when he was disturbed by a sudden draft in the room. He looked up to discover that one wall of his workshop and the top one thousand feet of a mile-thick mountain were no longer in the immediate vicinity.

As it turned out, his crude device did not impart to the mountain all of the thrust inherent in the crystal. The mountain top reached only to the orbit of Jupiter, where it settled down to become its newest satellite. Coincidental with Dr. King's experiment, intensive astronomical work was going on with Jupiter as its prime object. The capturing of the satellite was observed and recorded independently by at least six observatories, including the one on Tycho.

Subsequent investigation of the time involved to project this mass disclosed that Dr. King had invented a faster than light drive.

Further work, all of a mathematical nature, disclosed to Dr. King the proper method of enclosing these crystals in a unit to drive space ships to the stars. Coincidental with his work on the propulsor units he made a startling discovery which led to his special project.

Dr. King invented perpetual motion.

A series of complicated equations indicated to Dr. King that if he enclosed six of the crystals in the business end of a pendulum, and started the pendulum oscillating, it would tick-tock for all eternity.

This discovery began a five-year program that ended with a full scale press conference. The purpose was to unveil the building designed to protect this pendulum for all eternity, and of course to unveil the discovery of perpetual motion at the same time.

This building was designed to be Dr. King's monument to his own genius. It was a large rambling structure in which the pendulum was displayed by viewing it through a large hole in a brick wall. All of Dr. King's considerable savings had gone into designing a computer, the heart of his protective system. The computer was programmed to protect the ticking of the pendulum under every conceivable circumstance. So thorough was this programming that special devices were installed to keep the building and its precious cargo moving in earth's projected orbit if, through some gigantic mishap, the earth was reduced to cosmic dust. The switch that would impart the initial pulse to the pendulum would also start the computer operating, rendering the entire structure totally inviolable.

With a flourish, Dr. King pulled the switch.

Nothing happened.

There was an embarrassed shuffling of feet by the reporters. Then, as Dr. King became more exasperated, the reporters became amused. The amusement turned to open laughter when Dr. King, frantic with fear, rushed to the door to check the wiring on the inside of the building.

The door would not open. The computer was at work guarding a nonfunctioning machine.

He rushed to the open hole in the wall, intending to provide the initial pulse necessary to start the pendulum swinging by pushing. He found that the computer had designed a force field to keep him from entering. Frustrated and at his wit's end, he flew into a rage which ended in a fatal heart attack when he heard one reporter laughingly say to him: "Don't let it get you down, Doctor. You've beat the jinx. In one step you've gone from 'Side-Effect-Charlie' to 'No-Effect-Charlie.'"

It would be comforting to be able to assure everyone that the reporter in question was correct. Unfortunately Dr. King's monument did work, and probably will work for all eternity. The day after Dr. Charles King had his unfortunate heart attack a homesick astronomer on Sirius reported to his superior, and subsequently to the entire populated universe, that when he turned his telescope on the Solar System he discovered that it had acquired a new motion.

The entire system swung back and forth like a pendulum.

Our eastern seaboard, extending from the New South Wales border in the south, a few miles to the south of the 28th degree of south latitude, to Cape York, some 20 miles north of the 11th degree of south latitude, contains our best districts for the growth of tropical and semi-tropical fruits. The coastal climate, however, varies considerably, and is governed by the proximity or otherwise of the coast ranges. When they approach the coast there is always more rainfall, and as they recede the rainfall decreases. With one or two exceptions, where the coastal range is a considerable distance inland, the eastern coastal districts have a sufficient rainfall for the successful culture of most fruits, though they are subject to a dry spell during winter and spring. During this period of the year, the weather is extremely enjoyable; in fact, it is hard to better it, even in our extreme North. But as summer approaches, thunderstorms become prevalent, and are accompanied by more or less humid conditions, which, though good for fruit-development, are not quite so enjoyable as the drier months. Summer is our rainy season, and the rainfalls are occasionally very heavy. The weather is warm and oppressive, particularly in the more tropical districts; but these very conditions are those that are best suited to the production of tropical fruits. The climate of those districts having the heaviest summer rainfall is somewhat trying to Europeans, particularly women, but it is by no means unhealthy, and in the hottest parts, having the coast range nearly on the coast, there is, within a few miles, a tableland of from 2,000 to 4,000 feet elevation, where the climate is cool and bracing, and where the jaded man or woman can soon throw off the feeling of lassitude brought about by the heat and humidity of the seaboard. In autumn the weather soon cools off, drier conditions supervene, and living again becomes a pleasure in one of the best and healthiest climates to be met with anywhere. Practically all the district under review has a sufficient rainfall for the growth of all fruits suitable to the climate, though there are occasionally dry spells during spring, when a judicious watering would be a great advantage. This does not imply a regular system of irrigation, but simply the conserving of surplus moisture in times of plenty by means of dams across small natural watercourses or gullies, by tanks where such do not occur, or from wells where an available supply of underground water may be obtained. The water so conserved will only be needed occasionally, but it is an insurance against any possible loss or damage that might accrue to the trees during a dry spell of extra length. So far, little has been done in coastal districts in conserving water for fruit-growing, the natural rainfall being considered by many to be ample; but, in the writer's opinion, it will be found to be a good investment, as it will be the means of securing regular crops instead of an occasional partial failure, due to lack of sufficient moisture during a critical period of the tree's growth. The average yearly rainfall in the eastern seaboard varies from 149 inches at Geraldton to 41 inches at Bowen, the mean average being about 90 inches to the north and 49 inches to the south of Townsville. Were this fall evenly distributed throughout the year, it would be ample for all requirements. Unfortunately, however, it is not evenly distributed, the heavy falls taking place during the summer months, so that there is often a dry spell of greater or less extent during the winter and spring, during which a judicious watering has a very beneficial effect on fruit trees, and secures a good crop for the coming season. The rainfall shows that there is no fear of a shortage of water at any time, the only question is to conserve the surplus for use during a prolonged dry spell. These conditions are extremely favourable for the growth of all tropical and semi-tropical fruits, as during our period of greater heat, when these fruits make their greatest call for moisture, there is an abundance of rain, and during the other portions of the year, when the call is not so heavy, it is usually an inexpensive matter to conserve or obtain a sufficient supply to keep the trees in the best of order. Throughout the southern half of this seaboard frosts are not unknown on low-lying ground, but are extremely rare on the actual coast, or at an elevation of 300 to 400 feet above the sea, so much so that no precautions are necessary to prevent damage from frost. We have, unlike Florida and other parts of the United States of America--great fruit-growing districts--no killing frosts, and now, at the close of one of the coldest winters on record, and one of the driest, nowhere have our pineapples--fruit nor plants--been injured, except on low-lying ground, over in the Southern part of the State, and mangoes, bananas, &c., are uninjured.

In the more tropical North frosts are unknown on the coast, and there is no danger to even the most delicate plants from cold.

Running parallel with the coast we have a series of ranges of low mountains, running from 2,000 feet to nearly 6,000 feet, the general height being from 2,000 to 3,000 feet, and at the back of these ranges more or less level tablelands, sloping generally to the west. On and adjacent to these ranges in the Southern part of the State, there are fairly sharp frosts in winter, but the days are warm and bright. This is the district best adapted for the growth of deciduous fruits and vines, table varieties doing particularly well. It is a district well adapted for mixed farming and dairying, as well as fruit-growing; the climate is even and healthy, and is neither severe in summer nor winter. The average rainfall is some 30 inches, and is usually sufficient, though there are dry periods, when a judicious watering, as recommended for the coast districts, would be of great value to fruit and vegetable growers. The more northern end of this tableland country has a much better rainfall--some 40 inches per annum--and frosts, though they occur at times, are not common. Here the climate is very healthy, there are no extremes of heat and cold, and, lying as it does inland from the most trying portion of our tropical seaboard, it forms a natural sanatorium to this part of our State.

Further west the rainfall decreases, the summers are hot--a dry heat, as distinct from the more humid heat of the coast, and much more bearable. There are frequent frosts in winter, particularly in the Southern part of the State. Fruit-growing is only carried on to a slight extent at present, and then only with the help of water, but when the latter is obtainable, very good results are obtained. Grapes do well, both wine and table, and for raisin-making. Citrus fruits are remarkably fine, the lemons especially, being the best grown in the State. The trees are less liable to the attack of many pests, the dryness of the air retarding their development, if not altogether preventing their occurrence. The date palm is quite at home here, and when planted in deep sandy land, and supplied with sufficient water, it is a rapid grower and heavy bearer. As an offset to the smallness of the rainfall, there is a good supply of artesian water, distributed over a wide range of country, that can be obtained at a reasonable rate, and that is suitable for irrigation purposes. All bore water is not suitable for irrigation, however, as some of it is too highly mineralised, but there are large areas of country possessing an artesian supply of excellent quality for this purpose. It will thus be seen that we have in Queensland, roughly, three distinct belts of fruit-growing country--

So far, I have confined my remarks mainly to the climatic side of fruit-growing, and, before dealing with the growing of the different kinds of fruit, I will say a few words about our fruit soils, and will deal with them in districts, as I have endeavoured to do in the case of climate.

True scrub lands are not by any means the most difficult to clear, though to a "new chum" the work will appear at first of a Herculean character. Brushing the dense undergrowth and then felling the timber at a face costs from ?1 10s. to ?2 per acre, according to density, size of timber, and proportion of hardwood trees contained in it, and once this is done the fallen mass is allowed to become thoroughly dry, when it is burnt off. A good fire is half the battle, as the subsequent work of burning off the heavy timber left from the first burn is comparatively light. No stumps are taken out, as the bulk are found to rot out in a few years, and their presence in the soil is no detriment to the planting of such crops as bananas or even citrus fruit trees. No special preparation of the land, such as breaking up, &c., is necessary prior to planting. Holes are dug, trees or bananas are planted, and the whole cultivation for the first few years consists in keeping down weed growths with the chipping hoe. Once the stumps have rotted out the plough and other implements of culture take the place of the hoe. These soils are especially adapted for the growth of oranges, limes, mandarins, mangoes, bananas, pineapples, papaws, custard apples, strawberries, and cape gooseberries in the South; in fact, for nearly every kind of tropical and semi-tropical fruit.

Some basaltic soils are occasionally covered with forest in the place of scrub, or a mixture, part scrub and part forest. Forest country, as distinct from scrub, is open-timbered country, with little undergrowth, and no vines or other creepers. The timbers are also, as a rule, very hard, and the stumps will not rot out. Such land, when at all heavily timbered, is much harder to clear and get ready for fruit-growing than true scrub, as all timber must be felled and burnt off, and all stumps and roots taken out, so that the land can be thoroughly broken up and brought into a good state of tilth prior to planting. These soils are suitable to the growth of similar fruits to the true scrubs, but, as a rule, they are not as rich. The second class of soils suitable to fruit-growing are of alluvial origin, and are of a sandy, loamy nature, of fair depth. They are usually met with along our creeks and rivers, or in the deltas of our rivers. In their virgin state they are either covered with scrub or forest, or a mixture of both, but the growth is seldom as strong as on the red volcanic soils. Heavy alluvial soils are not suitable for fruit culture, and are much more valuable for the growth of farm crops, but the light sandy loams and free loams of medium character suit all kinds of fruit to perfection. These soils usually are easy to work. They retain moisture well when well worked, and frequently they are capable of being irrigated, either from adjacent creeks or rivers, or by water from wells. These soils are some of our best for citrus fruits, and are well adapted for the growth of pineapples and bananas, as well as most other tropical fruits, when free from frosts. The third class of soils are free sandy loams, either scrub or forest. They are of various colours, and range in texture from light sandy loams to medium loams; they possess excellent drainage, and though, when covered with forest, they are not naturally rich, they make excellent fruit soils, and respond rapidly to systematic cultivation and manuring. They are usually of sandstone or granitic origin, and, when covered with scrub in the first place, grow good crops for the first few years, when they become more or less exhausted in one or more available plant foods, and require manuring. These soils, like the sandy alluvial loams, are easy to work, retain moisture well when kept in a state of perfect tilth, and respond readily to manuring. They will grow all kinds of fruits when free from frost. There are other soils on which fruit can be grown, but those mentioned represent those most suitable. The land on which these soils occur is often much broken, particularly in rich scrub country; it is fairly level when of alluvial origin, and more or less rolling, as a rule, when of a sandy loamy nature. High, ridgy, free, loamy country is usually the most free from frost, and alluvial flats the most liable to it.

Starting from the Southern part of the State, adjoining the New South Wales border, the fruit soils are all of granitic origin. The country is much broken, but between the ridges and along the creek flats there is a considerable area possessing soils varying from a coarse, granitic, gritty soil to a fine granitic soil; that on the creeks of an alluvial nature, but still granitic. These soils vary considerably in quality, but are, as a rule, easy to work and retain moisture well. They are covered with open forest and are particularly adapted to the growth of apples, plums, peaches, and grapes, though other deciduous fruits are grown but not to the same excellence as those mentioned. Proceeding north the fruit soils are either sandy loams or loams of a brownish colour of volcanic origin. The former are suitable for almonds and wine grapes, and the latter for peaches, apricots, pears, apples, and especially olives. Further north a few of these fruits may be grown on loamy soils, together with citrus fruits, but, commercially, deciduous fruits are confined to the southern end of this district, the winter temperature being too high for their successful growth further north, as the trees get no winter rest, hence do not mature their fruit-bearing wood properly.

At the Southern end of the State the fruit soils are all of a sandy nature. Nothing else is used in any quantity, as sandy soils alone will retain sufficient moisture for the growth of grapes and fruit trees during dry spells, and even then only when kept well and deeply worked. Further north, where suitable artesian water is available, the best fruit soils are also free loams of a sandy nature, either alluvial or open forest soils, but deep, and possessing perfect drainage, as irrigation on land without good natural drainage is fatal to fruit culture. These sandy loams are also easy to work; though by no means rich, they, on account of their depth, grow good crops of fruit by means of irrigation, and the fruit, such as dates, oranges, lemons, grapes, &c., is of very fine quality. The fruit soils of this district are covered either with open forest--the trees being of comparatively small size--or with a scrubby undergrowth through which a few larger trees are scattered. Nearly all the timber of this district is extremely hard, is more or less stunted, and burns readily, hence clearing is not a very expensive item.

Having now given a very brief description of our climate and the fruit-soils in our principal fruit-producing centres, we will next consider the culture of those fruits which are grown in commercial quantities in the different parts of the State, as well as that of a few less well-known fruits which show especial promise. We will first deal with our tropical fruits, of which the first to be considered is the banana, as its production greatly exceeds that of any other tropical fruit, and, as far as Australia is concerned, this is the only State in which it is grown in commercial quantities. From tropical fruits we will go on to semi-tropical fruits, then to temperate fruits and vines.

THE BANANA.

Under the heading of "Banana," all kinds of plantains will also be included, as they belong to one and the same family. The members of this family of plants are all tropical, and produce the most typical and best known tropical fruits.

The rank luxuriance of the growth of this class of fruits, their handsome foliage, their productiveness, their high economic value as food, and their universal distribution throughout the tropics, all combine to place them in a premier position. As a food it is unequalled amongst fruits, as no matter whether it is used green as a vegetable, ripe as a fruit, dried and ground into flour, or preserved in any other way, it is one of the most wholesome and nutritious of foods for human consumption. It is a staple article of diet in all tropical countries, and the stems of several varieties make an excellent food for all kinds of stock.

In Queensland, the culture of bananas is confined to the frostless belts of the eastern seaboard, as it is a plant that is extremely susceptible to cold, and is injured by the lightest frosts. It is grown in favourable locations in the South, where it produces excellent fruit, but its cultivation is much greater in the North, where the rainfall is heavier and the average annual temperature greater. In the Southern part of the State its cultivation is entirely in the hands of white growers, who have been growing it on suitable soil in suitable localities for the past fifty years or even more. I recently saw an old plantation that was set out over twenty years ago, and the present plants are still strong and healthy, and bearing good bunches of well-filled fruit, so that there is no question as to the suitability of the soil or climate. Bananas do best on rich scrub land, and it is no detriment to their growth if it is more or less covered with stones as long as there is sufficient soil to set the young plants. Shelter from heavy or cold winds is an advantage, and the plants thrive better under these conditions than when planted in more exposed positions. Bananas are frequently the first crop planted in newly burnt off scrub land, as they do not require any special preparation of such land, and the large amount of ash and partially burnt and decomposed vegetable mould provide an ample supply of food for the plants' use. Bananas are rank feeders, so that this abundance of available plant food causes a rapid growth, fine plants, and correspondingly large bunches of fruit. Though newly burnt off scrub land is the best for this fruit, it can be grown successfully in land that has been under cultivation for many years, provided that the land is rich enough naturally, or its fertility is maintained by judicious green and other manuring. In newly burnt off scrub land all that is necessary is, to dig holes 15 to 18 inches in diameter, and about 2 feet deep, set the young plants in it, and partly fill in the hole with good top soil. The young plant, which consists of a sucker taken from an older plant, will soon take root and grow rapidly under favourable conditions, producing its first bunch in from ten to twelve months after planting. At the same time that it is producing its first bunch it will send up two or more suckers at the base of the parent plant, and these in turn will bear fruit, and so on. After bearing, the stalk that has produced the bunch of fruit is cut down; if this is not done it will die down, as its work has been completed, and other suckers take its place. Too many suckers should not be allowed to grow or the plants will become too crowded, and be consequently stunted and produce small bunches. All the cultivation that is necessary is the keeping down of weed growth, and this, once the plants occupy the whole of the land, is not a hard matter. A plantation is at its best when about three years old, but remains profitable for six years or longer; in fact, there are many plantations still bearing good fruit that have been planted from twelve to twenty years. Small-growing or dwarf kinds, such as the Cavendish variety, are planted at from 12 to 16 feet apart each way, but large-growing bananas, such as the Sugar and Lady's Finger, require from 20 to 25 feet apart each way, as do the stronger-growing varieties of plantain. Plantains are not grown to any extent in Queensland, and our principal varieties are those already mentioned, the Cavendish variety greatly predominating. In the North, the cultivation of this latter variety is carried out on an extensive scale, principally by Chinese gardeners, who send the bulk of their produce to the Southern States of the Commonwealth. The industry supports a large number of persons other than the actual producers of the fruit, and forms one of our principal articles of export from the North. As many as 20,000 or more large bunches of bananas frequently leave by a single steamer for the South, and the bringing of this quantity to the port of shipment gives employment to a number of men on tram lines and small coastal steamers. The shipment of a heavy cargo of bananas presents a very busy scene that is not soon forgotten, the thousands of bunches of fruit that are either piled up on the wharf or that are being unloaded from railway trucks, small steamers or sometimes Chinese junks, forming such a mass of fruit that one often wonders how it is possible to consume it all before it becomes over-ripe. Still, it is consumed, or, at any rate, the greater portion of it is, as it is the universal fruit of the less wealthy portion of the community, the price at which it can be sold being so low that it is within the reach of everyone. A banana garden in full bearing is a very pretty sight, the thousands of plants, each with their one or more bunches of fruit, as, where there are several stems it is not at all uncommon to find two or more bunches of fruit in different states of development on the same plant, forming a mass of vegetation that must be seen to be appreciated. This is the case even with dwarf-growing kinds, but with strong-growing varieties, such as the Lady's Finger, the growth is so excessive that the wonder is, how the soil can support it.

THE PINEAPPLE.

If there is one fruit that Queensland can grow to perfection, it is undoubtedly the pineapple. This is not merely my own personal opinion, but is the universal admission of all who are qualified to judge. On many occasions I have taken men thoroughly conversant with pineapple-growing, and who knew what a good fruit really is, through some of our plantations, where I have given them fruit to test, and, without exception, they have had no hesitation in saying that they have never tasted better fruit. Our fruit has a firmness, freedom from fibre, and a flavour that is hard to beat. It is an excellent canning fruit, superior in this respect to the Singapore article, which it surpasses in flavour. This is admitted by English and European buyers, and its superiority is bound eventually to result in a great increase in canning and the establishment of large works run on thoroughly up-to-date lines.

Like the banana, the pineapple is a tropical fruit, and is very sensitive to cold, hence its culture is confined to frostless districts. It is grown all along our eastern seaboard, where, when planted in suitable soils and under suitable conditions, it is, undoubtedly, our hardiest fruit, and is practically immune from any serious disease. Its culture is entirely in the open, no shelter whatever being given, so that we are not put to the great expense that growers of this fruit in Florida and some other pineapple-producing countries must incur if they wish to secure a crop. Here we have no severe freeze-outs, and, though dry spells retard the growth at times, we have never suffered any serious injury from this cause. In the Southern part of the State, the coolness of the winter retards growth somewhat, and occasionally the tops of the leaves and young fruit are slightly injured, particularly in low-lying land, or where the plants are growing on land having a cold subsoil. When grown under more favourable conditions, however, they sustain no injury, and produce fruit, more or less, all the year round. Pines are always in season, though there are times when they are comparatively scarce. There are usually two main crops a year--viz., a summer and a winter crop. The former is the heavier of the two, and the fruit is decidedly the best, as its sugar contents are much higher. The main summer crop ripens in the North from the beginning of November, and in the South from January to as late as March in some seasons. The main winter crop is usually at its best in July and August, but there is always more or less fruit during the other months of the year. The pineapple likes a warm, free, well-drained soil, that is free from frost in winter, and that will not become soured by heavy rain during summer. Sandy loams are, therefore, our best pineapple soils, though it does well on free loams of basaltic or alluvial origin. Unlike the banana, the pineapple does not do too well in newly burnt off scrub land, owing to the difficulty in working the ground and keeping it clean. It requires a thorough preparation of the soil prior to planting in order to be grown to perfection. In the case of new land of suitable texture, the timber should all be burnt off, and all stumps and roots taken out of the soil, which should then be carefully broken up and reduced to a fine tilth, all weed or grass growth being destroyed. It should then be again ploughed, and, if possible, subsoiled, so as to permit of the roots penetrating the ground to a fair depth instead of their merely depending on the few top inches of surface soil. Careful preparation of the land and deep stirring prior to planting will be found to pay well, and turn out far the cheapest in the end. Given suitable soil, well prepared, the growing of pineapples is not at all difficult, as the plants soon take root, and once they became established, they prove themselves to be extremely hardy. Pines will grow and thrive on comparatively poor soil, provided it is of suitable texture, but in such soils it is necessary to supplement the plant food in the soil by the addition of manures, if large fruit and heavy crops are to be obtained. Pineapples are propagated by means of suckers coming from the base of fruit-bearing plants, or from smaller suckers, or, as they are termed, robbers or gill sprouts that start from the fruiting stem just at the base of the fruit. They are also sometimes propagated by means of the crown, but this method is usually considered too slow. Well-developed suckers are usually preferred, as these come into bearing earliest, but equally good, if not better, returns are obtained by planting gill sprouts. The latter have the advantage in that they always develop a good root system before showing signs of fruit, hence their first crop is always a good one, and the fruit is of the best, whereas suckers sometimes start flowering as soon as they are planted, before they are properly established, with the result that the first fruit is small and inferior, and the plants have to throw out fresh suckers before a good crop is produced. Gill sprouts are slower in coming into bearing than suckers, but the results are usually more satisfactory. Like the banana, once a pineapple plant has borne fruit the fruiting stalk dies down, and its place is taken by one or more suckers, which in their turn bear fruit and die. Pineapples are planted in Queensland in several ways, but by far the most common method is to set the suckers out in single or double rows, from 8 to 9 feet apart, with the plants at from 1 to 2 feet apart in the row. The rows soon increase in width by the growth of suckers, and the throwing up of ratoons--surface roots thrown off from the original plant, which send up plants from below the ground as distinct from suckers, which come from the base or even higher up the stem of a fruiting plant. It is not at all an uncommon thing to see the rows grown together, so that the plantation appears to be a solid mass of plants, but pathways have to be kept between the rows to permit of gathering the fruit, manuring, &c. Pineapples have been grown in the Brisbane district for the past sixty years, and I have been shown beds of plants that have not been replanted for over forty years that are still producing good fruit. This shows how well at home this fruit is with us; but, in my opinion, it is not desirable to keep the plants so long in the same ground, as the finest fruit is always obtained from comparatively young plantations, the older ones producing too large a proportion of small fruit. From the Brisbane district this fruit has spread all over the eastern coast, and its production is increasing rapidly in several districts. Once the pine is planted, its cultivation is comparatively simple. If in single or double rows, all weed growth is kept down between the plants, and the ground between the rows is kept in a state of good cultivation by means of ploughing or cultivating, the soil being worked towards the rows so as to encourage the formation of suckers low down on the fruiting plants. Manure is given when necessary, the manure being worked in on either side of the rows.

Queensland possesses many advantages respecting the growth of this fruit as compared with other countries in which it is grown commercially, which may be briefly enumerated as follows:--

These are enough reasons to show that in the pineapple we have a fruit well suited to our soil and climate, a fruit in the cultivation of which there is room for great extension, and which will provide a living for many industrious settlers.

THE MANGO.

This magnificent fruit, which is practically unknown outside of the tropics, has become as hardy as a forest tree throughout our eastern seaboard, wherever it is planted out of frost. It has been named, and well named too, the apple of Queensland, as it stands as much neglect, and can be grown with as little care and attention as, or even less, than that given to the apple-trees in many of the Somerset or Devonshire orchards. It will not, however, stand frost. Droughts and floods have little effect on it; it will grow in any soil, from a sand to a heavy loam, amongst rocks, or on a gravelly or shaley land. Naturally, it does best in good land, but there are hundreds of cases where trees are doing well and bearing heavily on land that is by no means fruit land. The mango is one of our handsomest fruit trees; the symmetry of its growth, its large glossy leaves, the delicate colouring of its young growth, which is of different shades in different varieties, the abundance of fruit that it produces, varying in colour from dull-green to yellow, red, or even purplish tints, all render it conspicuous. As well as being one of our handsomest, it is also one of our most widely distributed fruits, being found growing luxuriantly the whole length of our eastern seaboard. A few trees are also to be met with inland in districts that are free from frosts, so that it stands both the dry heat of the interior and the humid heat of the coast. As a tropical fruit it naturally reaches its greatest perfection under our most tropical conditions, the trees there growing practically wild, requiring little if any attention, making a rapid growth, coming into bearing early, and producing heavy crops of fruit. Further south the growth is somewhat slower, though the trees grow to a large size and bear heavily. It is one of the easiest of trees to grow, as it is readily propagated by means of seed. In many plantations thousands of young seedlings may often be seen growing under the old trees, the seeds having taken root without even having been planted. In most cases it is propagated from seed, the stones of fruit showing especial merit being planted either in a nursery, or, better, still, where the tree is to remain permanently, as it usually does better when so planted than when grown in a nursery and thence transplanted to its permanent location. The land should be well worked prior to planting, and the young trees require to be kept free from weeds and undergrowth till such time as they occupy the whole of the ground, when they are able to look after themselves, and require no further attention, at any rate in the warmer parts. It is not at all uncommon to come across a mango-tree, in full bearing, in vigorous health, that is growing wild, the result of a stone that has been thrown away by someone who has eaten the fruit. The young tree has not only been able to hold its own against all kinds of indigenous growths, but has developed into a vigorous, healthy tree, thus showing that it is perfectly at home, and that the soil and climate of Queensland suit it to perfection. The fact that by far the greater portion of our mango-trees have been grown from seed has resulted in the production of innumerable varieties, many of which are of decidedly inferior quality, as one never knows when planting the seed what the resultant fruit is going to be like. One is more likely to get good fruit by planting the seeds from selected fruit of the highest quality, but is by no means certain to do so, as a number of seeds always revert to inferior types. This has had a bad effect on our mango industry, and has been apt to give the fruit as a class a bad name, so much so that we find it difficult to get our Southern neighbours to take to it at all readily. I can quite understand anyone, whose first experience of a mango is that of an inferior fruit, full of fibre, and having a distinctly disagreeable flavour, condemning the particular fruit, but because there are inferior fruits one should not condemn the whole without knowing what a really good mango is like.

The mango grows to a large size here, even when comparatively young. I know trees over 50 feet in height, having a spread of the branches of more than 60 feet, a main trunk nearly 3 feet in diameter, that are under thirty years old, and that have borne from 1 to 2 tons of fruit for a single crop. Hundreds of tons of fruit go to waste annually for want of a market, or are consumed by farm animals, as the consumption of the fruit is practically confined to this State, and the production is greater than we can consume, despite the fact that mangoes are in season from the end of September to March, and that they are a favourite fruit with all who have acquired a liking for them. In addition to the consumption of the fruit in its fresh state, a quantity is converted into chutney, but this is so small that it has no appreciable effect on the crop as a whole. The unripe fruit makes an excellent substitute for apples, and is used stewed or for pies or tarts, and when sliced and dried it may be stored and used in a similar manner to dried apples.

In addition to its value as a fruit, the mango forms a handsome ornamental tree, and one that provides a good shade for stock. It is very free from disease, as with the exception of one or two species of scale insects, which do not cause any very serious damage, it has few serious pests. It is a fruit that is bound sooner or later to come into more general favour, particularly when the qualities of the finer varieties are better known. Until quite recently it was considered to be one of the most difficult trees to propagate by means of grafting or budding, hence its propagation has been practically confined to raising it from seed, but now we have found out how to work it by means of plate-budding, and are able to perpetuate our best sorts true to kind. This is sure to lead to a general improvement of our existing varieties, as old trees can be worked over by this means, or young trees of approved kinds can be grown in a nursery and distributed.

The fruit is very wholesome, is much appreciated by all who have acquired a taste for it, can be used fresh or dry, ripe or unripe, and cans well. It is a great addition to our list of purely tropical fruits, and finds a place in all orchards or gardens where it is capable of being grown.

THE MANGOSTEEN.

THE PAPAW.

Continuing our list of tropical fruits, we now come to the papaw, one of our most wholesome and useful fruits. It is grown all along our eastern seaboard in situations that are free from frost. It comes into bearing early, and is a heavy cropper. Like the other tropical fruits already described, it does best in our warmer parts, coming to maturity earlier, and producing better fruit. In many of the Northern coastal scrubs it is often met with growing wild, and producing fruit in abundance, the seeds from which the trees have been produced having been dropped by birds or distributed by other natural agencies. The papaw fruit resembles a rock melon somewhat in shape and flavour, the fruit being produced in the axil of the leaves all along the main stem, where they are clustered thickly together. The tree does best on well-drained soils, and is very sensitive to the presence of clay or stagnant water at the roots, hence it usually does best on scrub land or land well supplied with humus. It is propagated entirely from seed, which grows readily in such soils, and under favourable conditions will bear its first fruit when about ten to twelve months old, and continue to bear for three or four years or even longer. When the trees becomes old, however, the fruit decreases in size and deteriorates in quality, so that it is necessary to plant a number yearly in order to keep up a regular supply. It is a very handsome tree, with large spreading leaves on long stems, beneath which is its cluster of fruit--as many as 100 fruits being sometimes found in different stages of development on the one plant. The fruit ranges in size from 2 lb. to some 6 lb. in weight, and when ripe it is of a greenish-yellow or sometimes orange colour. The flesh is yellow, and when quite ripe it is moderately juicy, and of a flavour that it not always appreciated at first, but which one soon becomes very partial to. It more nearly resembles the flavour of a rock melon than that of any other fruit, and the seeds, which are found clustered in the centre of the fruit, have a flavour that closely resembles that of seeds of the nasturtium. Both the seeds and the fruit contain an active principle called papain, which is really a vegetable pepsin, that has the effect of greatly assisting in the assimilation of all food with which it is eaten, hence it is a valuable remedy in the case of dyspepsia, and persons who take the fruit regularly are never subject to this exceedingly troublesome disease. The fruit can be used both as a vegetable and as a fruit, the former in its green state, when it is boiled and served with melted butter, resembles a vegetable marrow or squash, but is superior to either of these vegetables. As a fruit it is either used by itself, or in conjunction with other fruits it forms the basis of a fruit salad. It is largely used in the North, and its cultivation is steadily spreading South, as its valuable properties are becoming better known. Its cultivation is very simple. The seeds are either planted where the tree is to remain, or are raised in a bed and transplanted to their permanent position in the orchard when strong enough to stand shifting, care being taken to select a dull moist day. The young plants are protected from the sun for a few days till they have become established, after which all that is necessary is to keep down weeds and to work the soil round them, taking care not to injure the roots. A good mulch of decomposed vegetable matter round the plants is an advantage, but they are usually so easily grown that little extra care is given to them. The papaw bears male and female flowers, which may be on the same trees, but are usually on different trees, so that it is usual to speak of male and female trees. This is, however, a mistake, as according to Bailey the plant is polygamous--that is to say, male, female, or hermaphrodite flowers may be found on the same or on distinct plants. The male flowers are usually on long scantily-branched auxiliary panicles, whereas the female flowers are mostly in the axils of the leaves close to the stem. The two trees are not distinguishable from each other till they come into flower, hence it is advisable to set the young plants fairly close together--say, 6 feet apart--and thin out the male trees when same can be distinguished by their blossoms.

Besides its use as a fruit and vegetable, the papaw makes a fair conserve and an excellent sauce, and its medicinal principle, "papain," is an article of commerce.

THE COCOA-NUT.

Although this palm can be grown for ornamental purposes as far south as Brisbane, its cultivation on commercial lines will be confined to the coast district north of Townsville, and to the islands off the coast, as, in order to develop its fruit to perfection, it requires a tropical climate. Where the climate is suitable it does well, it makes a rapid growth, and bears heavy crops of nuts. Old palms on the beach at Cairns compare favourably with any growing in the South Seas, and I am of opinion that its culture in commercial quantities on suitable land will be found profitable. The cocoa-nut palm does best right on or adjacent to the seashore, in comparatively poor sandy soil--soil that is usually of little value for general crops, though it will grow mangoes well. So far, it is not grown in any large numbers, and although there is a ready sale for the ripe nuts, there is no attempt to make copra or to utilise the coir. Copra is the dried flesh of the nut, from which oil is extracted, and is largely used in the manufacture of soap, candles, &c., the refuse left after the oil has been extracted being used for cattle feed. Coir is the fibre surrounding the nut, and is used for the manufacture of matting, door mats, &c.
