NOTES ON THE MAPS AND CHARTS

The maps included in this work have been photographed from a globe of Mars specially made for the purpose from various charts. In all the maps the south is at the top and the north at the bottom; and the series shows the general surface configuration all round the planet, together with the principal canal lines which have been observed; but many other canal lines exist, especially on the dark areas near the south pole. These lines are usually straight and uniform in width throughout their whole length: indeed it is difficult to mark them upon a globe so that they shall appear as regular and uniform as they are actually seen on the planet.

The names on the maps are those now generally accepted and used by astronomers.

The chart showing the relative positions of the Earth and Mars during the years 1909-10 is reduced and modified from one prepared accurately to scale by the author for his own use in connection with the book. From it the reader will gain a clear idea of the shape of the two orbits and how they are placed with regard to each other.

It also shows the course supposed to be taken by the air-ship on its outward and homeward journeys, and the point reached when one of the travellers desired to turn back; together with the alternative routes which were then discussed.

This chart, and the other one showing the positions of the two planets at different oppositions of Mars, will enable the reader to understand how it is that Mars approaches so much nearer to the earth at some oppositions than it does at others. The positions of the oppositions from 1916 to 1922 are only approximations, as no exact data are yet available. The earth is closest to the orbit of Mars about the 27th of August each year, and if Mars comes into opposition about that date it is then only about thirty-five million miles away. If, however, the opposition occurs near the 22nd February, the earth is then at its greatest possible distance from the orbit of Mars, and that planet will then be over sixty million miles away: appearing very much smaller than when at its most favourable point of approach.

On the 18th of September, 1909, Mars was only slightly over thirty-six million miles from the earth, and it will be fifteen years before such a favourable situation again occurs.

The nearest point of approach does not necessarily occur on the actual date of the opposition. In 1907 Mars was in perigee, as it is termed, seven days after the opposition; while in 1909, perigee was before opposition.

The view of the moon is photographed from a large coloured drawing by the author, which occupied many months in preparation and execution. It shows all the principal formations seen through the telescope as the moon passes through its various phases, but it must be understood that the formations can never all be seen at one view as shown in this picture. As the sun rises on any particular formation the details are gradually revealed by the long shadows cast by the more elevated portions when the sun is low down in the lunar sky. As the sun rises higher and higher the shadows grow shorter and shorter, and when the sun is vertically over the formation the shadows entirely disappear; all details are thus rendered invisible.

When the moon is full the sun is practically vertical over the whole lunar surface, so the only details then seen are those which are vaguely brought out by differences in tint.

The bright ray-streaks are only suggested in the picture, because, if shown complete, they would have the same effect as upon the moon, viz. they would entirely obliterate all the formations over which they passed.

The Key Map indicates the principal lunar formations, and includes the names of those mentioned in the book.

The last two plates in the book are from drawings made at the telescope by the Rev. T. E. R. Phillips. The opposition of 1909 was not favourable for the observation of Martian details from England; for although the planet was near to us, it was too low down in the sky; and many of the nights were either cloudy or misty.

THE SUN, MOON, AND PLANETS

WE START ON A VERY LONG VOYAGE

"Well, I suppose it is about time to get ready for starting?"

The speaker was a smart, well-set-up man about forty-three years of age, whose keen and alert expression, clear eyes and well-cut features were a true index to the intellectuality and integrity of his character; whilst his closely compressed lips and the deep vertical line down the centre of his forehead betokened a dogged perseverance in carrying into effect anything he might undertake.

John Yiewsley Claxton, for that was his name, was my very intimate friend of at least twenty-five years' standing; and during the greater portion of that time he had been my constant companion. We had passed through many trials and troubles together, but a better friend and companion no man could have desired.

We were just finishing a last quiet smoke and chat in my snuggery at Norbury, near Croydon, preparatory to starting off on a very long journey for which all arrangements had been completed, and we had risen early that morning in order to have everything in readiness.

John took his pipe from his lips as he spoke, then, rising, stretched out his arms and braced himself up like one ready and eager for any emergency; the next minute he was smoking in his usual calm and thoughtful manner. I rose when he did, then giving a few final instructions to Mrs. Challen, my housekeeper, we bade her "good-bye" and stepped out on to the lawn, thence crossing over to a gate at the far end of the garden, we passed into an extensive field and walked toward a large shed that stood near its centre.

It was a most beautiful evening near the beginning of August 1909, clear and calm. The sun had only just passed below the horizon, the sky immediately above it being a rippled glory of gold, merging higher up into gold flecked with crimson, then into a placid sea of pale apple-green. Above this were fleecy clouds of delicate rose-pink, which reflected their splendours upon the higher parts of the surrounding hills, the latter standing out clear and sharp, and glowing with roseate hues, whilst their bases were seen dimly as through a thin veiling of purple mist.

Surely nothing could be better for the commencement of our long-planned trip. The moon would not rise until about a quarter-past nine, and darkness would have descended by the time we were ready to start. This was exactly what we required, because we did not wish either our preparations or our departure to be observed.

Just as we arrived within hail of the shed the door opened, and a rugged-featured man with sandy hair stepped out. This was Kenneth M'Allister, our engineer and general factotum in all mechanical matters--a typical specimen of a Scotch engineer. He had followed his profession in its different phases on tramp-steamers, on ocean liners, naval gunboats, and even on battle-ships, besides having served for several years in the workshops of a great firm of electrical engineers.

Whether repairing a broken propeller-shaft two or three scores of tons in weight, the most intricate machinery, or the most delicate electric mechanism, he was equally at home and sure in his work; in fact nothing seemed to come amiss to him. His machinery was always the object of his most anxious care, and, providing that all worked satisfactorily, nothing else troubled him much.

"Well, M'Allister," I called to him, "is everything ready for our trip to-night?"

"Heh, mon," he replied, "everything is all ready; will you look in and take a turn round the ship?"

"Certainly we will," I answered; so we all went into the shed, where we gazed with equal pride and satisfaction upon the splendid shining object which was housed therein. Here, in perfect readiness for its destined service, was our air-ship--if it could be so called--upon which we three had expended years of thought, experiment, and work.

Outwardly it was shaped somewhat like a fish, being constructed of a special metal--our joint invention--which we had named "martalium." The metal was composed of aluminium and two other rarer metals which, when combined together, produced a substance almost as light as aluminium, yet many times harder and tougher than case-hardened steel; whilst its surface shone like burnished silver and could never in any circumstances become tarnished or affected by rust.

The ship was ninety-five feet in length, and its diameter twenty feet in the broadest part, tapering off to a point at either end.

With the exception of the steering and balancing fans, there was no machinery whatever visible on the exterior of the vessel. Several windows along each side, together with a few at the top and bottom of the vessel, gave light to the interior, and would allow for observations being made in any direction. These windows were all constructed of a special toughened glass obtained from Vienna, very thick and warranted to withstand the hardest blows. Along each side of the vessel there was an observation platform or gallery on to which the exterior doors opened, and each gallery was provided with a protecting railing.

The interior of the ship was divided into five separate compartments, the rear one being the general living and sleeping room, having observation windows so arranged as to command an outlook in all directions. The next compartment was mainly a store-room, but, like all the others, could be used for observation purposes; next to that was a small compartment intended for a special purpose which will hereafter be apparent; then another containing water storage, apparatus for compressing or rarefying air, as well as machinery for producing the latter chemically.

Lastly, right in the forepart of the vessel was M'Allister's special sanctum, containing the driving, lighting, warming, and steering machinery, but electric buttons and switches were also provided for controlling these in every compartment, so that whichever one we happened to be in we were prepared for all emergencies. Periscopes capable of being turned in all directions also communicated with every compartment, thus we could always see what might be around us.

All the machinery was either electric or magnetic, some of it being very simple; other portions were extremely intricate, but nearly all was the outcome of our joint inventions. Such parts as could not profitably be made by ourselves had been carefully distributed between several firms of founders and engineers, in order that none could have any means of discovering the use to which they were intended to be put. The whole of the shell of the vessel was double, with a packed space between the two skins; and each door opened into a small lobby, having another door on the farther side, to ensure that every part might be kept perfectly air-tight when required.

When the vessel was out in the open we congratulated ourselves upon its splendid proportions and business-like appearance.

I asked M'Allister whether "he was satisfied with the result of our labours?"

"Mon," he replied, "she's grand, and it's fine to have the handling of such machinery; everything works as slick as grease!" It was a pleasure to hear him talk about his machines, for he was always so enthusiastic where they were concerned.

"Now," I suggested, "before we start we'll give our good ship her name."

"Bravo!" said John Claxton, "and we'll drink to her success, a good voyage and a safe return"; and he was so struck by the brilliancy of his idea that he actually took his pipe from his lips, and, holding it in his hand, regarded it with thoughtful contemplation for quite three minutes.

I accordingly went to the store-room and brought out two bottles of champagne. Directly M'Allister saw them he entered a vigorous and emphatic protest, saying, "Heh, Professor! you're surely not going to celebrate this most auspicious event with such poor fizzy stuff as champagne? Let's have a wee drop of good old Scotch whisky, and do the thing properly!"

John Claxton here interposed: "Let M'Allister have his whisky if he prefers it, and we'll have the 'fizz'!" So I went laughing to the store again and returned with a bottle of special Scotch, whereat M'Allister's eye gleamed as he smiled approval.

Claxton and I at once stepped on board the vessel, and having just set the machinery slowly moving so as to raise the vessel a few feet, I put on the neutral power so that the ship remained poised in the air. M'Allister ran the trolley back into the shed, closed the doors, and switched off the electric current; then climbed the extending ladder, and came on board, John steadying the vessel by an anchor rope in the meantime.

John and I were standing outside on the platform, from whence, looking toward the house, we could plainly see Mrs. Challen at the open door of our sitting-room waving farewell to us--her figure silhouetted against the bright light of the room. We waved back to her in response, but I am very doubtful if she could see our signal, as she was looking into the darkness.

We now rose rapidly as M'Allister switched on more power, and far away to the northward we could see over the whole extent of the vast metropolis, with its countless miles of lighted streets. On turning towards the east the Crystal Palace, which was lighted up, was a very conspicuous object against the skyline over the Sydenham hills.

John, when he saw it, remarked that "it would have been an appropriate tribute to our enterprise if the Palace Company had provided one of their grand firework displays as a send-off for us"; "but," he added, "these companies will never do what is expected of them!" On the westward side the lights all along the hill where Sutton lies were clearly visible; farther off was Epsom, and, with the aid of a glass, we could even faintly see the lights of Guildford in the far distance.

Nearly south of us Croydon seemed from our altitude to lie almost beneath our vessel. We directed our course towards the south-east, passing over the railway-station at Thornton Heath, with Croydon to the right of us, just as the clock of the Croydon Town Hall was striking nine. The long lines of lighted streets made a fine panorama, and we could trace the lights of the moving tram-cars out to Anerley, South Norwood, Purley, Wallington, and Mitcham.
