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.
There is a considerable area of land suitable to the culture of this fruit on our Northern coast, which is at present lying idle, that, in my opinion, can be turned to a profitable use by planting it in cocoa-nuts as, in addition to utilising land otherwise of little value, we would be building up a new industry. The trees come into bearing in about eight years after planting the seed, and will continue to produce crops for many years without any attention. Care will have to be given for the first few years, whilst the plants are small, to keep down undergrowth and to prevent fires from running through the plantation, but, once fairly established, the plants will look after themselves. A cocoa-nut plantation gives a distinctly tropical look to the district in which it is grown, and the palms, particularly when young, are very ornamental; when old the long bare stems detract somewhat from the beauty of the top. It is a palm that I believe has a good future before it in the North, and for that reason I have included it amongst our tropical fruits, though it is cultivated at present more as an ornamental plant than as an article of commerce.
THE GRANADILLA.
A vine, belonging to the natural order Passifloreae, that produces one of our most delicious tropical fruits. The papaw and the passion fruit belong to this same order. It can be grown all along our eastern seaboard, but comes to greatest perfection in the North. The fruit is of a pale greenish-yellow colour, cylindrical in shape, and varies in weight from about 1 to 5 lb., the largest fruits being produced on a sub-species. The fruit consists of an outer pulpy covering, which can be used for cooking if desired, which surrounds a cavity filled with seeds which are encased in a jelly-like mass. This is the portion eaten, and to use an Americanism, "It is not at all hard to take." It is either eaten by itself, or is used in conjunction with papaw and other fruits to make a fruit salad, a dish that is fit for the food of the gods, and once taken is never forgotten.
The granadilla is easily grown from seed, and the plants are trained on an overhead trellis, the fruit hanging down on the underside. It is a heavy bearer, and once planted requires little attention. It requires a free, warm soil, that is fairly rich, to be grown to perfection, hence it is most commonly grown on scrub land. It can, however, be grown on any well-prepared land of a free nature. Unfortunately, it is a difficult fruit to ship any distance, hence its consumption is mainly confined to the districts in which it is grown, and where, needless to say, it is greatly appreciated. It is in fruit more or less all the year round, its main crop being in early spring in the North, and during the summer months further South. It is sometimes made into jam or jelly, but when preserved loses much of its characteristic flavour.
THE PASSION FRUIT.
This fruit is very closely related to the granadilla, but is much hardier than it, and can be grown to perfection much further South. It is not injured by frost to any extent in any part of coastal Queensland, and can be grown a considerable distance inland. It is more rightly a semi-tropical than a tropical fruit, though, as it is so nearly related to the granadilla, I have included it amongst the tropical fruits. It is also a vine, and, when grown commercially, is trained along a horizontal trellis, in a somewhat similar manner to a grape vine. It is readily grown from seed, and will produce fruit in less than twelve months from the time that it is planted, and will continue to bear fruit for some years. It does best on a free, warm soil of fair quality, though it may be grown anywhere with care, and often thrives well in very poor soils with the addition of manure. It is found growing wild on the borders of many of our scrubs and elsewhere, the seeds having been deposited by birds or other agencies, and under such conditions it produces an abundance of fruit. The fruit is of a roundish oval shape, and is of a dark-purple colour. It is about the size of a large hen's egg, the outer skin being hard and shell-like, and the centre filled with the seeds, which are surrounded with a jelly-like mass and a yellowish pulp. It is a very fine flavoured fruit, and is universally liked. It is grown in considerable quantities in the Southern part of the State, and is one of our commonest fruits. It has usually two crops a year--a summer and a winter crop--but can be got to produce its fruit at any particular time that is desired by systematic pruning at different times of the year. It is often grown over sheds, dead trees, fallen logs, &c., which it covers with a mass of dense green foliage, and converts what would otherwise be an unsightly object into an ornament. The illustration herewith shows this well, and gives a good idea of the growth of a single vine. Commercially it is grown on trellis, so that the land between the rows can be kept well cultivated, and also to permit of ease in the gathering of the fruit. When ripe, the fruit drops, and the gathering is usually from the ground. The fruit carries well, but will not keep for any length of time, as it shrivels up. It is principally used as a fresh fruit, though it is also made into jam or jelly, and it often forms part of a fruit salad, taking the place of the granadilla. It has few pests, and is one of the easiest fruits to grow.
CUSTARD APPLES.
Under this heading I will include all the Anonas, such as the sour sop, sweet sop, bullock's heart, and cherimoya. The sour sop is purely tropical, and is very sensitive to frost, but the other species are by no means so tender, and can be grown anywhere along the coast where the soil is suitable, as well as at many inland places. All the species produce very fine fruits, that vary somewhat in shape, in the roughness of the skin, and in size. The sour sop is the largest, and attains a size of 6 to 8 lb. The fruit is covered with soft spines, and is of an irregular oval, or even pyriform, shape. It ripens very soon after it is gathered, consequently cannot be sent any distance. It is a pleasant fruit of an aromatic sub-acid flavour. The pulp surrounding the seeds is of a woolly consistency, and this is surrounded by a custard-like mass which is much appreciated by those who have acquired a liking for it. It is a comparatively uncommon fruit, and is confined to the tropics.
The sweet sop is the commonest of the Anonas, and is grown throughout a considerable part of coastal Queensland. It is usually of an irregular roundish shape, very full of seeds, which are surrounded by a custard-like pulp of very pleasant flavour. It is usually a heavy bearer, and is the variety most commonly met with in our fruit stores. The tree is hardy and is easily grown.
The bullock's heart is a stronger-growing variety than the previous one, the fruit is larger, and, as its name implies, heart-shaped. It is also fairly seedy, the pulp of a light-brown colour, and more gritty, and not, in my opinion, of first-rate quality. It is most commonly grown in the North, where it is a very hardy and prolific tree.
The cherimoya is the best of the custard apples. The tree is a strong grower, with large handsome leaves, but, as a rule, it is not a very heavy bearer. There are many varieties, the fruit of which varies considerably in size and shape, and the skin is sometimes smooth and sometimes warted, or even covered with short soft spines. It has usually comparatively few seeds, and these are surrounded by a rich custard-like pulp, which in the better kinds is of very fine flavour, and is generally much liked. The fruit is not a good keeper, still, given careful handling and packing, it can be kept for nearly a week. All custard apples are easily raised from seed, but the better varieties are propagated by grafting strong seedlings with wood taken from a tree producing fruit of especial merit. Any good fruit soil will grow them, and they do not require any especial treatment.
There are still a large number of tropical fruits that I have not mentioned, but space will not permit of my giving them more than a passing notice, as they are not of any great value from a commercial standpoint at present. Of these fruits the litchi, whampee, averoha, longan, vi-apple, and Chinese mangosteen are practically confined to the North. The guava, of which there are many species, grows anywhere; in fact, it is a pest in many cases, taking complete possession of the land. It is not cultivated to any great extent, as it grows so readily without, and, further, it harbours several pests whose presence it is desirable to remove from the orchard. It is a useful fruit for home consumption, as it stews well, makes an excellent jam, and its jelly is one of the best.
The rosella, a species of hibiscus, is an annual fruit that is grown to a considerable extent in several parts of the State, and is used for pies, jams, and jellies. The latter is remarkably good, equal to that made from the red currant of colder climes, and will no doubt become an article of export at no very distant date. The fruit also dries well, and makes an excellent pickle. It is raised from seed, the young seedlings being set out in well-prepared land when all danger of frost is past. It is a rapid grower, and forms a bush some 4 feet across by 4 or 5 feet high. It is a heavy bearer, and the fruit meets with a ready sale. To do well, the plants require a warm, free, well-drained soil, as they do not thrive where there is any stagnant water at or near the roots.
The avocado or alligator pear is not grown to any extent, though it thrives well, particularly to the north of the tropic of Capricorn, and can also be grown successfully as far south as the New South Wales border. It is a fruit that deserves to be cultivated to a much greater extent than it is at present, and once it becomes better known I have no doubt that it will be planted in considerable numbers, and prove a very welcome addition to our already long list of fruits, as it is unequalled, in my opinion, as a salad. As far as my experience goes, it is likely to become a profitable fruit to grow, as once persons acquire a liking for it, they become very partial to it, and eat it whenever they can get it.
In addition to purely tropical fruits a number of semi-tropical fruits are grown on our eastern seaboard, but are not entirely confined thereto, as many of them are cultivated to a considerable extent in some parts of our coastal and inland tablelands, particularly in sheltered positions. Under the heading of semi-tropical fruits, all kinds of citrus fruits, persimmons, loquats, date palm, wine palm, pecan nut, Brazilian cherry, Natal plum, ki-apple, and many other fruits are included, as well as several fruits that more properly belong to the temperate regions, such as Japanese plums, Chickasaw plum, peaches of Chinese origin, figs, mulberries of sorts, strawberries, cape gooseberries, &c. Of all of these the citrus fruits, which include the orange, mandarin, Seville, lemon, lime, grape fruit, kumquat, citron, and pomelo are by far the most important, and are grown successfully over a very large portion of the State, so that we will consider them first.
CITRUS FRUIT.
Quite a number of fruits are included under this heading, and all reach a very high state of perfection in this State. The whole of the family, the lemon-shaped citron excepted, is noted for the beauty and symmetry of growth that its trees make, and I know of few more beautiful sights in the vegetable world than a well-kept citrus grove in full bearing. Take the common round orange as an example, its well-balanced and evenly grown head, its dark glossy green foliage, its wealth of white blossoms, which perfume the whole neighbourhood, or its mass of golden fruit between its dark-green leaves, render it one of the most beautiful of fruit trees at all times, but especially so when covered with blossoms or ripe fruit. A typical Queensland grove is even more beautiful than those of many other places, as the vigour and size of our trees, their exceptionally healthy appearance, their dark foliage, and the heavy crop of high-class fruit that they bear, are at once evident to a stranger who has never seen the orange grown under such favourable conditions as are experienced here. The yield is often so heavy that the trees actually bend to the ground with the weight of their fruit, and a stack of props has to be used to prevent the tree from splitting into pieces. Those who have seen the enormous crops of apples that are produced on some trees in Tasmania or the old cider orchards of Devon or Somerset can form an idea of the crops; but the writer, who has seen both, as well as our Queensland trees, has no hesitation in saying that a Queensland mandarin can give points to either as a heavy cropper; in fact, if it has a fault, it is its proneness to overbear, particularly when young. This all tends to prove how well adapted Queensland is to the growth of citrus fruits, and were I asked to select a country particularly suited to their culture I should have no hesitation in naming this State, as I know of nowhere where their culture can be carried out with less trouble, or where the trees will produce better fruit or heavier crops. Queensland may well be termed the home of citrus fruits, as we have no less than three native species which are indigenous to the State, and are by no means uncommon in our scrubs. Their presence gives unmistakable proof of the suitability of this State for the culture of fruits of the same family, so that I think a short description of these native species may not be out of place, but will be of some interest to my readers.
No fruits are more generally distributed or have a wider range in this State than those of the Citrus family, as, with the exception of the colder parts of the Downs, where the winter temperature is too low, the Gulf country, and the dry Western districts, where there is no water available for irrigation, they can be grown from one end of the State to the other, provided that they are planted in suitable soil, and that, in the drier parts, there is an available supply of suitable water with which to irrigate them during the prevalence of long dry spells. The country adjoining the eastern seaboard, extending from the Tweed River in the South to Cooktown in the North--a distance of about 1,100 miles, and extending inland for nearly 100 miles--is naturally suited to the growth of citrus fruits, and there is probably no country in the world that is better adapted to, or that can produce the various kinds of these fruits to greater perfection or with less trouble, than this portion of Queensland. Of course, the whole of this large area is not adapted for citrus culture, as it contains many different kinds of soils, several of which are not suitable for the growth of these fruits, and there is also a large extent of country which is too broken and otherwise unsuitable. At the same time there are hundreds of thousands of acres of land in this area in which the soil and natural conditions are eminently suited to the growth of citrus fruit, and in which the tenderest varieties of these fruits may be grown to perfection without the slightest chance of their being injured by frost; and where the natural rainfall is such that, provided the trees receive ordinary care and cultivation, there is seldom any necessity for artificial irrigation. At the present time there are hundreds of citrus trees growing practically wild in different parts of the coastal country that are in vigorous health and producing heavy crops of good fruit, even though they are uncultivated, unpruned, unmanured, and have to hold their own against a vigorous growth of native and introduced shrubs, trees, and weeds. When the orange, lime, citron, or common lemon become established under conditions that are favourable for their proper development, they apparently become as hardy as the indigenous plants, and are able to hold their own against them, thus showing how well the climate and suitable soils of coastal Queensland are adapted for the cultivation of citrus fruits. The commercial cultivation of citrus fruits is at present practically confined to this coastal area, the most important centres, starting from the South, being Nerang, Coomera, Redland Bay, Brisbane, Enoggera, Gatton, Grantham, Toowoomba, North Coast line from North Pine to Gympie including the Blackall Range and Buderim Mountain; the Wide Bay district, including Maryborough, Tiaro, Mount Bauple, Gayndah, Pialba, and Burrum; the Burnett district, including Bundaberg and Mullet Creek; the Fitzroy district, including Rockhampton and Yeppoon; Bowen, Cardwell, Murray River, Tully River, Cairns and district, Port Douglas, and Cooktown. In addition to these districts a few citrus fruits are grown at Mackay, Townsville, and several other places. Citrus fruits are also grown further inland, but their cultivation here is largely dependent on the ability to supply the trees with suitable water for irrigation during dry spells. Frosts have also to be taken into consideration, for, though the days are warm, the temperature often falls considerably during the night, owing to the great radiation, and citrus-trees in districts like Roma, Emerald, &c., are liable to injury thereby. West of Emerald, at Bogantungan, Barcaldine, and other places, citrus fruits do very well with irrigation. Some of the finest lemons, Washington Navel, and other improved varieties of oranges are grown here to perfection, the lemons especially being of high quality, and curing down equal to the imported Italian or Californian article. The soil in many of the inland districts is well suited to the culture of citrus fruits, and when the trees are given the necessary water, and are uninjured by frost, they produce excellent fruit. I stated, some short distance back, that there is probably no country in the world that is better adapted to the cultivation of or that can produce the various kinds of citrus fruits to greater perfection or with less trouble than the eastern seaboard of Queensland. To many of my readers this may seem to be a very broad statement; but I am certain that, if suitable trees are planted in the right soil and under favourable conditions, and are given anything like the same care and attention that is devoted to the culture of citrus fruits in the great producing centres for these fruits in other parts of the world, we have nothing to fear either as regards the cost of production or the quality of the fruit produced. In order to exemplify this, it may be interesting to compare our capabilities with those of the principal citrus-producing districts north of the equator. To begin with, I will take Florida, which more nearly approaches our climatic conditions than any other citrus-growing country that I know of, and which is noted for the excellence of its citrus fruit, and we find that we have all its advantages except that of proximity to the world's markets, without its disadvantages. We have a better and richer soil, requiring far less expensive artificial fertilisers to maintain its fertility, and at a very much lower price. We can grow equally as good fruit; in fact, it is questionable if Florida ever produced a citrus fruit equal in quality to the Beauty of Glen Retreat Mandarin, a Queensland production. We get as heavy, if not heavier, crops, and our trees come into bearing very early. We have no freeze-outs similar to those which have crippled the industry in Florida so severely in the past that many of their wealthy growers are actually covering in whole orchards of many acres in extent as a protection from frost. This covering-in is accomplished by means of a framework of timber having slat-work or panel sides and tops--in fact, by enclosing their orchards in a huge elaborate bush-house, which is further protected by the heat produced by six large heating stoves or salamanders to each acre of trees enclosed. If it pays the Florida growers to go to all this expense in order to prevent freeze-outs and to produce first-class fruit, surely we can compete with them when a seed stuck in the right soil under favourable conditions will produce a strong, vigorous, healthy tree, bearing good crops without any attention whatever.
In comparing Queensland with the citrus-producing districts of Southern Europe, we have the advantage of better and cheaper land, absence of frost, more vigorous growth, earlier maturity of the trees, and superior fruit; but with the advantage of cheaper and more skilful labour, especially in the handling and marketing of fruit, and proximity to the world's markets in their favour.
As compared with California, our soil is no better than theirs, but it costs much less, and their citrus industry is dependent on artificial irrigation, their natural rainfall being altogether inadequate for the growth of citrus fruits. Californian conditions more nearly approach those of our inland districts, such as Barcaldine, with the exception that the only rainfall in California is during the winter, whereas in Barcaldine and similar districts the heaviest fall is during the summer months, but, in both, the successful culture of these fruits depends on irrigation.
In Jaffa, also, where the oranges are of large size and extra quality, the trees have to be carefully irrigated and manured, as these operations are found to be essential to the production of marketable fruit.
These few instances show how favourably the conditions prevailing in Queensland compare with those of the great citrus-growing districts of Europe and America, especially in the matter of soil and climate, and I feel confident that, if the industry were taken up in the same business-like manner that it has been done in California and Florida, we could easily hold our own against any part of the world. In comparing Queensland with the rest of the world we have the advantage--also shared by New South Wales and South Africa--of ripening our fruit at a time of the year which is the off season in the citrus-producing countries to the north of the equator, so that our fruit does not clash with theirs, their ripening period and ours being at different times of the year. As regards our Australian market, our fruit ripening earlier than that of the Southern States, we are enabled to dispose of a considerable portion of our crop in the Southern markets before the local fruit is ready for gathering. This gives us three markets--first, a local one; secondly, a Southern one; and, finally, when this demand is supplied, an oversea market to Europe, America, and the East.
When grown under favourable conditions, citrus-trees are heavy bearers in this State, it being no uncommon thing to meet with seedling or worked orange-trees of from ten to twelve years of age producing over twenty cases of marketable fruit to the tree, averaging about 10 dozen medium-sized fruit.
Mr. A., Blackall Range, marketed 7-1/4 cases per tree from a row of twenty-five Beauty of Glen Retreat Mandarins, planted April, 1900. A return of ?1 10s. per tree.
Mr. B., from the same district, averaged 7 cases of Washington Navel Oranges per tree from trees six years old, which realised ?1 15s. per tree, and 8 cases of Beauty of Glen Retreat Mandarins from trees of the same age. The navels were large, and averaged 5 dozen per case, and the mandarins 10 dozen per case.
Mr. C, another district, averaged 6 cases of Valencia Late Oranges, from trees six years planted, and 10 cases per tree from Emperor Mandarins, nine years old.
One twelve years old orange-tree in this district produced over 25 cases of fruit.
Mr. D., same district as last; Washington Navels averaged 10 cases per tree, ten years planted, and have borne regular crops since three years old.
Numerous other cases might be given, but the above are sufficient to show the earliness at which our trees bear, and the crops they yield. Trees in full bearing often yield up to 40 cases, but these are usually old seedlings, which bear a very heavy crop one year and a comparatively light crop the next. All the instances I have quoted are from worked trees, which are found to give the most regular and constant yields. Until quite recently, citrus-trees were almost entirely grown from seed in this State, with the result that we have a very large number of types, and many crosses between different species. This was not advisable, as a uniformity in type is desirable for marketing, hence the greater number of trees now being planted are of selected varieties of proved merit. Many of the seedlings have produced most excellent fruit, but a seedling has usually the disadvantage of being very full of seeds, and having a lot of rag as compared with the worked varieties, which have either no seeds or very few seeds and little rag. Seedlings are also of many types, and they produce a lot of small fruit, thereby making an uneven sample, whereas worked trees produce fruit even in size and quality. Seedlings are probably the hardiest, and will stand the most neglect, but experience is showing that worked trees are the most profitable to grow. The growth of all kinds of citrus-trees from seed is a very simple matter, all that is necessary being a well-prepared seed bed of friable soil that is partially shaded from the heat of the sun, so as to protect the young plants. Selected, fully ripe fruit from well-grown, prolific, healthy trees is taken, and the seeds sown in rows in the seed bed, or broadcast when weeds are not likely to be any trouble. Fresh seed germinates quickly, and the young plants are soon ready to be transplanted into the nursery bed, where they are either worked over or allowed to remain seedlings. At twelve months old, from seed, a tree will have a stem-diameter of about 3/4-inch, and a height of 3 to 4 feet, a growth about twice that made in the Southern States.
The Washington Navel, the variety of orange most commonly grown in California, does remarkably well on our rich volcanic scrub soils, where it has proved itself a regular bearer of high-class fruit. The Mediterranean Sweet Orange, Valencia Late, and Jaffa also do well in many parts, the Valencia Late adapting itself to most districts. Many other kinds of oranges are grown, but the varieties mentioned are some of the best, and are the ones now being planted in the greatest quantity.
In mandarins, all kinds do remarkably well, and I never saw this fruit produced to greater perfection in any part of the world than it is in Queensland. The varieties most commonly grown are: The Emperor or Canton, the Scarlet or Scarlet Emperor, Thorny or Tangerine, and Beauty of Glen Retreat, though there are many types of seedlings in addition to these well-known sorts. The grape fruit which is now so popular in America does well, but, so far, has not taken on in our markets. Citrons grow practically wild, and produce good fruit, for which there is a limited demand for peel. Their cultivation could be extended with ease were there a better demand for peel. The Seville Orange, which is used for the manufacture of marmalade, is an exceptionally hardy and prolific tree, and, were it required, we could easily grow enough of this fruit to supply the world. Lemons do best inland, or at an elevation of some 2,000 feet above sea-level, as this fruit is apt to become too coarse in the skin when grown in a humid climate. In suitable localities very good fruit can be grown, which compares very favourably with the European or American grown fruit.
The lime does well in the more humid districts, taking the place of the lemon, and one variety--the Tahiti--has proved itself to be a heavy and regular bearer. The West Indian lime, from which the lime juice of commerce is made, is very easily grown, particularly in the more tropical parts, where it is often met with growing in an entirely uncultivated condition, and bearing heavy crops of fruit. Kumquats are easily grown, and are heavy bearers, and all the different types of pomelos or shaddocks do well. Seedlings of the latter are very hardy, as they are deep-rooted plants that stand dry weather well and are, consequently, not liable to injury during dry spells. There is very little demand for the fruit, but I am of opinion that the seedlings will prove to be of value as stocks on which to work our best kinds of oranges.
The culture of all kinds of citrus fruits, when grown in suitable soil, is by no means difficult, as it consists mainly of keeping the land well stirred and keeping down all weed growth during dry spells, the keeping of the trees well pruned out in the centre, and the keeping in check of all diseases, both insect and fungus. Although citrus fruits are subject to many pests, they are for the most part easily kept in check by either spraying or cyaniding, or both, provided that reasonable care is taken, and the pests are destroyed before they have obtained control. Taken as a whole, our citrus fruits are remarkably clean, and compare more than favourably with those grown in the Southern States. The culture of these fruits is extending rapidly, with a corresponding increase in production, but, despite this, our prices have been better during the past season than for some years, as the quality of our fruit is such that it will command a good market. When properly handled, it has good keeping qualities, and I have no doubt that we will, in time, be able to supply the markets of the Old and New Worlds with good fruit, in the best of condition, at the time of the year that their markets are bare of locally-grown citrus fruit.
There is a good opening for the growth of citrus fruits in this State, as the writer knows of no country where they do better, where they can be produced with as little trouble and expense, where they can be successfully grown over such a large area, or where the soil and climate is more suited to the production of fruits of the highest quality as in Queensland.
THE PERSIMMON.
This exceedingly handsome fruit of Japanese origin is grown to a high state of perfection in this State, particularly in the coastal districts south of the tropic of Capricorn. It is a fruit of comparatively recent introduction, the oldest trees being less than thirty years of age, but has already become widely distributed, as well as a favourite fruit amongst many. It is a very showy fruit when well grown, but must be thoroughly ripe before it is eaten, as, if not, it is extremely astringent, and anyone who has tackled an unripe fruit has no wish to repeat the experience in a hurry. There are many varieties of this fruit, some of which are seedless, and others more or less seedy. The seedless kinds are usually preferred, as, as well as being seedless, they are the largest and handsomest fruit. The different kinds vary considerably in the size of tree, habit of growth, foliage, size and colour of fruit, &c. All are easily grown, and most kinds are good and regular bearers. They do well on any fruit soil, and some of the dwarf-growing kinds are well adapted for growing in private gardens, on account of the small amount of room they take up. The trees are deciduous, and, as a rule, are not much troubled with pests. So far, the use of the fruit is confined to its consumption fresh, though in Japan it is dried in a similar manner to apricots or peaches.
THE LOQUAT.
A handsome evergreen tree, that can be grown in the more Southerly coast districts, in the foothills of the coast range, and on the coast tablelands. There are several types of the fruit, whose chief value consists in that it ripens its fruit in early spring, when there is a shortage of stone fruits, and that it withstands wind well, so makes a good break for the protection of exposed orchards. Its cultivation is not extensive, nor is it likely to become so.
THE DATE PALM.
Although this extremely valuable fruit is grown in this State more as an ornament than for its commercial value, there is nothing to prevent its culture on a scale sufficiently large to supply the Australian requirements. It is grown in many places along the coast, as well as in the foothills country of the coastal range, but it does best in situations that more nearly resemble its natural habitat--viz., in districts having a hot dry air, a deep sandy loam or sandy soil, and a good supply of moisture in the soil. This latter condition does not occur naturally, but can be supplied artificially in our Western lands, where there is a good supply of artesian water of a quality suitable to the plants' requirements. Here the date palm thrives, and produces huge bunches of fruit. Little, if any, cultivation is necessary when once the palm is firmly established; provided it has an ample but not excessive supply of moisture, it is able to take care of itself.
The date palm is a dioecious plant--that is to say, the male organs, or stamens, are produced on one plant, and the female organs, or pistils, on another, and this necessitates the growing of the two sexes in proximity to each other, in order that the female flowers may be fertilised and produce perfect fruit. This is best accomplished artificially, the pollen from a fully developed bunch of male flowers being shaken over the bunch of female flowers. Infertile fruit contains no seeds, and is of small size and inferior quality, whereas the fertile fruit is both large and good.
The date palm is a handsome ornamental plant, and in the hot and dry Western districts, where it thrives best, it forms a splendid shelter from the sun for both man and beast. So far, very little attention has been given to its growth, few persons knowing how to fertilise the flowers or even taking the trouble to see that they have plants of both sexes. There is no reason why this should be so, as there would be a good local demand for the properly-cured fruit, and I believe that, were its culture carried out in a thorough business manner, it would become a profitable industry, and one capable of supplying our Australian market.
THE PECAN NUT.
Another little-known fruit which does well in this State. It belongs to the hickory family, and closely resembles the walnut. There are trees now growing in the Maryborough district that are some 15 inches in diameter at the trunk, and from 40 to 50 feet in height, that bear regular and heavy crops of nuts, and that have stood drought and been under flood. For years the trees have received no cultivation, and they have shown themselves to be as hardy as the adjacent indigenous trees. The trees are easily raised from seed, and come into bearing in about eight years. Like all nut fruits, it is advisable to set the nut where the tree is to remain permanently, if it is possible to do so, as it produces a very deep taproot, with few laterals, and is consequently difficult to shift. The soil on which it does best is an alluvial loam, and, if possible, it should not be more than 30 feet to water, as the tree, being a very deep rooter, will penetrate a free soil to that depth. It will do on other free loamy soils, but will not make the same growth as when planted in free alluvials. It has been tested in several parts of the State, and it is probable that it will be found to thrive over a considerable area of the coastal and coastal tablelands districts. It produces an olive or acorn shaped nut, having a thin shell, and of a flavour closely resembling that of a good walnut, and will be a valuable addition to our list of nut fruits once it becomes better known.
JAPANESE PLUMS.
All varieties of this fruit thrive well and bear heavily in the more Southerly part of our coast country, as well as on the country immediately adjacent to it, the coastal tablelands, and several other parts of the State. The trees are rapid growers, come into bearing very early, and often bear enormous crops of fruit. They are good fruits for home consumption or for the fresh-fruit trade, but are not equal to European varieties of plums for preserving, drying, or jam-making. In this State they have one very great drawback, and that is their liability to the attack of the fruit fly, a pest that very frequently destroys the entire crop. For home use they are, however, a very useful fruit to grow, provided that the trees are kept dwarf, so that they can be covered with a cheap mosquito netting as a protection from the fly, as they are very easily grown, are by no means particular as to the kind of soil on which planted, and are heavy bearers.
CHICKASAW PLUMS.
This family of American plums does well in the same districts as the Japanese varieties just dealt with, but has the advantage of being resistant to the fruit fly. The trees are usually more or less straggling growers, the fruit is of small size, but good for cooking or jam-making. One or more of the varieties of this plum are bad setters, though they blossom profusely, but this may be overcome either by working two varieties which bloom at the same time on to the same stock, or by planting varieties that bloom at the same time together, as the pollen from the one will set the fruit of the other. It is a good plum for home use or marketing, despite its small size, as it is easily grown, requires little attention, and is not over particular as to soil.
CHINESE PEACHES.
Peaches of Chinese origin thrive well on the coast, and are extremely hardy. The fruit is not, as a rule, of high quality when compared with that of the Persian varieties, but their earliness and ease with which they can be grown causes them to be planted by many who have small gardens. Like the Japanese plums they are, however, very subject to the attack of fruit fly, and require to be kept dwarf and covered in a similar manner if any good is to be got from them. On the coast, they are practically evergreen, as they never lose their leaves entirely, and are in blossom during the winter. When grown on the tablelands, this early blossoming is a disadvantage, as the blossoms are liable to be injured by frost, but in these districts peaches of Persian origin can be grown instead.
