"Not much to be seen here," said Redgrave, as he came up the companion-way, "and I don't think it would be safe to go out. The attraction is so weak here that we might find ourselves falling off with very little exertion. Still, you may as well take a couple of photographs of the surface, and then we'll be off to Phobos."
Zaidie got her apparatus to work, and when she had taken her slides down to the dark-room, Redgrave turned the R. Force on very slightly and Phobos began to sink away beneath them. The attraction of Mars now began to make itself strongly felt, and the Astronef dropped rapidly through the eight thousand miles which separate the inner and outer satellites.
As they approached Phobos they saw that half the little disc was brilliantly lighted by the same rays of the sun which were glowing on the rapidly increasing crescent of Mars beneath them. By careful manipulation of his engines Redgrave managed to meet the approaching satellite with a hardly perceptible shock about the centre of its lighted portion, that is to say the side turned towards the planet.
Mars now appeared as a gigantic rosy moon filling the whole vault of the heavens above them. Their telescopes brought the three thousand seven hundred and fifty miles down to about ten. The rapid motion of the tiny satellite afforded them a spectacle which might be compared to the rising of a moon glowing with rosy light and hundreds of times larger than the earth. The speed of the vehicle of which they had taken possession, something like four thousand two hundred miles an hour, caused the surface of the planet to apparently sweep away from below them, just as the earth seems to glide from under the car of a balloon.
Neither of them left the telescopes for more than a few minutes during this aerial circumnavigation. Murgatroyd, outwardly impassive, but inwardly filled with solemn fears for the fate of this impiously daring voyage, brought them wine and sandwiches, and later on tea and toast and more sandwiches; but they took no moment's heed of these, so absorbed were they in the wonderful spectacle which was swiftly passing under their eyes.
The main armament of the Astronef consisted of four pneumatic guns, which could be mounted on swivels, two ahead and two astern, which carried a shell containing either one of two kinds of explosives invented by her creator.
One of these was a solid, and burst on impact with an explosive force equal to about twenty pounds of lyddite. The other consisted of two liquids separated by a partition in the shell, and these, when mixed by the breaking of the partition, burst into a volume of flame which could not be extinguished by any known human means. It would burn even in a vacuum, since it supplied its own elements of combustion. The guns would throw these shells to a distance of about seven terrestrial miles. On the upper deck there were also stands for a couple of light machine guns capable of discharging seven hundred explosive bullets a minute.
Professor Rennick, although a man of peace, had little sympathy with the laws of "civilised" warfare which permit men to be blown into rags of flesh and splinters of bone by explosive shells of a pound weight and upward, and only allow projectiles of less weight to be used against "savages." There was no humbug about him. He believed that when war was necessary it had to be war—and the sooner it was over the better for everybody concerned.
The small arms consisted of a couple of heavy ten-bore elephant guns carrying three-ounce melinite shells; a dozen rifles and fowling-pieces of different makes of which three, a single and a double-barrelled rifle and a double-barrelled shot-gun, belonged to her Ladyship, as well as a dainty brace of revolvers, one of half a dozen braces of various calibres which completed the minor armament of the Astronef.
The guns were got up and mounted while the attraction of the planet was comparatively feeble, and the weapons themselves therefore of very little weight. On the surface of the earth a score of men could not have done the work, but on board the Astronef, suspended in Space, her crew of three found the work easy. Zaidie herself picked up a Maxim and carried it about as though it were a toy sewing-machine.
