the planet is as two to fifteen. It was consequently to be expected that the extent of the Martial atmosphere, and its density even at the sea-level, would be far less than on the heavier planet. Rigging the air-pump securely round the aperture, exhausting its chamber, and permitting the Martial air to fill it, I was glad to find a pressure equal to that which prevails at a height of 16,000 feet on Earth. Chemical tests showed the presence of oxygen in somewhat greater proportion than in the purest air of terrestrial mountains. It would sustain life, therefore, and without serious injury, if the change from a dense to a light atmosphere were not too suddenly made. I determined then gradually to diminish the density of the internal atmosphere to something not very much greater than that outside. For this purpose I unrigged the air-pump apparatus, and almost, but not quite, closed the valve, leaving an aperture about the twentieth part of an inch in diameter. The silence was instantly broken by a whistle the shrillest and loudest I had ever heard; the dense compressed atmosphere of the Astronaut rushing out with a force which actually created a draught through the whole vessel, to the great discomfiture of the birds, which roughed their feathers and fluttered about in dismay. The pressure gauge fell with astonishing rapidity, despite the minuteness of the aperture; and in a few minutes indicated about 24 barometrical inches. I then checked the exit of the air for a time, while I proceeded to loosen the cement around the window by which I had entered, and prepared for my exit. Over a very light flannel under-vesture I put on a mail-shirt of fine close-woven wire, which had turned the edge of Mahratta tulwars, repelled the thrust of a Calabrian stiletto, and showed no mark of three carbine bullets fired point-blank. Over this I wore a suit of grey broadcloth, and a pair of strong boots over woollen socks, prepared for cold and damp as well as for the heat of a sun shining perpendicularly through an Alpine atmosphere. I had nearly equalised the atmospheric pressure within and without, at about 17 inches, before the first beams of dawn shone upward on the ceiling of the Astronaut. A few minutes later I stepped forth on the platform, some two hundred yards in circumference, whereon the vessel rested. The mist immediately around me was fast dispersing; five hundred feet below it still concealed everything. On three sides descent was barred by sheer precipices; on the fourth a steep slope promised a practicable path, at least as far as my eye could reach. I placed the weaker and smaller of my birds in portable cages, and then commenced my experiment by taking out a strong-winged cuckoo and throwing him downwards over the precipice. He fell at first almost like a stone; but before he was quite lost to sight in the mist, I had the pleasure of seeing that he had spread his wings, and was able to sustain himself. As the mist was gradually dissolving, I now ventured to begin my descent, carrying my bird-cages, and dismissing the larger birds, several of which, however, persistently clung about me. I had secured on my back an air-gun, arranged to fire sixteen balls in succession without reloading, while in my belt, scabbarded in a leathern sheath, I had placed a well and often tried two-edged sword. I found the way practicable, though not easy, till I reached a point about 1000 feet below the summit, where farther progress in the same direction was barred by an abrupt and impassable cleft some hundred feet deep. To the right, however, the mountain side seemed to present a safe and sufficiently direct descent. The sun was a full hour above the horizon, and the mist was almost gone. Still I had seen no signs of animal life, save, at some distance and in rapid motion, two or three swarms of flying insects, not much resembling any with which I was acquainted. The vegetation, mostly small, was of a yellowish colour, the flowers generally red, varied by occasional examples of dull green and white; the latter, however, presenting that sort of creamy tinge which I had remarked in the snow. Here I released and dismissed my birds one by one. The stronger and more courageous flew away downwards, and soon disappeared; the weakest, trembling and shivering, evidently suffering from the thinness of the atmosphere, hung about me or perched upon the cages.

      The scene I now contemplated was exceedingly novel and striking. The sky, instead of the brilliant azure of a similar latitude on earth, presented to my eye a vault of pale green, closely analogous to that olive tint which the effect of contrast often throws over a small portion of clear sky distinguished among the golden and rose-coloured clouds of a sunset in our temperate zones.

      The vapours which still hung around the north-eastern and south-eastern horizon, though dispelled from the immediate vicinity of the Sun, were tinged with crimson and gold much deeper than the tints peculiar to an earthly twilight. The Sun himself, when seen by the naked eye, was as distinctly golden as our harvest moon; and the whole landscape, terrestrial, aerial, and celestial, appeared as if bathed in a golden light, wearing generally that warm summer aspect peculiar to Tellurian landscapes when seen through glass of a rich yellow tint. It was a natural inference from all I saw that there takes place in the Martial atmosphere an absorption of the blue rays which gives to the sunlight a predominant tinge of yellow or orange. The small rocky plateau on which I stood, like the whole of the mountainside I had descended, faced the extremity of the range of which this mountain was an outpost; and the valley which separated them was not from my present position visible. I saw that I should have to turn my back upon this part of the landscape as I descended farther, and therefore took note at this point of the aspect it presented. The most prominent object was a white peak in the distant sky, rising to a height above my actual level, which I estimated conjecturally at 25,000 feet, guessing the distance at fifty miles. The summit was decidedly more angular and pointed, less softened in outline by atmospheric influences, than those of mountains on Earth. Beyond this in the farthest distance appeared two or three peaks still higher, but of which, of course, only the summits were visible to me. On this side of the central peak an apparently continuous double ridge extended to within three miles of my station, exceedingly irregular in level, the highest elevations being perhaps 20,000, the lowest visible depressions 3000 feet above me. There appeared to be a line of perpetual snow, though in many places above, this line patches of yellow appeared, the nearer of which were certainly and the more distant must be inferred to be covered with a low, close herbaceous vegetation. The lower slopes were entirely clothed with yellow or reddish foliage. Between the woods and snow-line lay extensive pastures or meadows, if they might be so called, though I saw nothing whatever that at all resembled the grass of similar regions on Earth. Whatever foliage I saw—as yet I had not passed near anything that could be called a tree, and very few shrubs—consisted distinctly of leaves analogous to those of our deciduous trees, chiefly of three shapes: a sort of square rounded at the angles, with short projecting fingers; an oval, slightly pointed where it joined the stalk; and lanceolate or sword-like blades of every size, from two inches to four feet in length. Nearly all were of a dull yellow or copper-red tinge. None were as fine as the beech-leaf, none succulent or fleshy; nothing resembling the blades of grass or the bristles of the pine and cedar tribes was visible.

      My path now wound steadily downward at a slope of perhaps one in eight along the hillside, obliging me to turn my back to the mountains, while my view in front was cut off by a sharp cross-jutting ridge immediately, before me. By the time I turned this, all my birds had deserted me, and I was not, I think, more than 2000 feet from the valley below. Just before reaching this point I first caught sight of a Martial animal. A little creature, not much bigger than a rabbit, itself of a sort of sandy-yellow colour, bounded from among some yellow herbage by my feet, and hopped or sprang in the manner of a kangaroo down the steep slope on my left. When I turned the ridge, a wide and quite new landscape burst upon my sight. I was looking upon an extensive plain, the continuation apparently of a valley of which the mountain range formed the southern limit. To the southward this plain was bounded by the sea, bathed in the peculiar light I have tried to describe, and lying in what seemed from this distance a glassy calm. To eastward and northward the plain extended to the horizon, and doubtless far beyond it; while from the valley north of the mountain range emerged a broad river, winding through the plain till it was lost at the horizon. Plain I have called it, but I do not mean to imply that it was by any means level. On the contrary, its surface was broken by undulations, and here and there by hills, but all so much lower than the point on which I stood that the general effect was that of an almost flat surface. And now the question of habitation, and of human habitation, seemed to be solved. Looking through my field-glass, I saw, following the windings of the river, what must surely be a road; serving also, perhaps, as an embankment, since it was raised many feet above the level of the stream. It seemed, too, that the plain was cultivated. Everywhere appeared extensive patches, each of a single colour, in every tint between deep red and yellowish green, and so distinctly rectangular in form as irresistibly to suggest the idea of
