would be insignificant indeed.

      To Conquer Another World.

      It was a wonderful undertaking and a strange spectacle. There was a feeling of uncertainty which awed the vast multitude whose eyes were upturned to the ships. The expedition was not large, considering the gigantic character of the undertaking. Each of the electrical ships carried about twenty men, together with an abundant supply of compressed provisions, compressed air, scientific apparatus and so on. In all, there were about 2,000 men, who were going to conquer, if they could, another world!

      But though few in numbers, they represented the flower of the earth, the culmination of the genius of the planet. The greatest leaders in science, both theoretical and practical, were there. It was the evolution of the earth against the evolution of Mars. It was a planet in the heyday of its strength matched against an aged and decrepit world which, nevertheless, in consequence of its long ages of existence, had acquired an experience which made it a most dangerous foe. On both sides there was desperation. The earth was desperate because it foresaw destruction unless it could first destroy its enemy. Mars was desperate because nature was gradually depriving it of the means of supporting life, and its teeming population was compelled to swarm like the inmates of an overcrowded hive of bees, and find new homes elsewhere. In this respect the situation on Mars, as we were well aware, resembled what had already been known upon the earth, where the older nations overflowing with population had sought new lands in which to settle, and for that purpose had driven out the native inhabitants, whenever those natives had proven unable to resist the invasion.

      No man could foresee the issue of what we were about to undertake, but the tremendous powers which the disintegrators had exhibited and the marvellous efficiency of the electrical ships bred almost universal confidence that we should be successful.

      Master Minds of the World.

      The car in which Mr. Edison travelled was, of course, the flagship of the squadron, and I had the good fortune to be included among its inmates. Here, besides several leading men of science from our own country, were Lord Kelvin, Lord Rayleigh, Professor Roentgen, Dr. Moissan—the man who first made artificial diamonds—and several others whose fame had encircled the world. Each of these men cherished hopes of wonderful discoveries, along his line of investigation, to be made in Mars.

      An elaborate system of signals had, of course, to be devised for the control of the squadron. These signals consisted of brilliant electric lights displayed at night and so controlled that by their means long sentences and directions could be easily and quickly transmitted.

      A Novel Signal System.

      The day signals consisted partly of brightly colored pennons and flags, which were to serve only when, shadowed by clouds or other obstructions, the full sunlight should not fall upon the ships. This could naturally only occur near the surface of the earth or of another planet.

      Once out of the shadow of the earth we should have no more clouds and no more night until we arrived at Mars. In open space the sun would be continually shining. It would be perpetual day for us, except as, by artificial means, we furnished ourselves with darkness for the purpose of promoting sleep. In this region of perpetual day, then, the signals were also to be transmitted by flashes of light from mirrors reflecting the rays of the sun.

      Perpetual Night!

      Yet this perpetual day would be also, in one sense, a perpetual night. There would be no more blue sky for us, because without an atmosphere the sunlight could not be diffused. Objects would be illuminated only on the side toward the sun. Anything that screened off the direct rays of sunlight would produce absolute darkness behind it. There would be no graduation of shadow. The sky would be as black as ink on all sides.

      While it was the intention to remain as much as possible within the cars, yet since it was probable that necessity would arise for occasionally quitting the interior of the electrical ships, Mr. Edison had provided for this emergency by inventing an air-tight dress constructed somewhat after the manner of a diver's suit, but of much lighter material. Each ship was provided with several of these suits, by wearing which one could venture outside the car even when it was beyond the atmosphere of the earth.

      Terrific Cold Anticipated.

      Provision had been made to meet the terrific cold which we knew would be encountered the moment we had passed beyond the atmosphere—that awful absolute zero which men had measured by anticipation, but never yet experienced—by a simple system of producing within the air-tight suits a temperature sufficiently elevated to counteract the effects of the frigidity without. By means of long, flexible tubes, air could be continually supplied to the wearers of the suits, and by an ingenious contrivance a store of compressed air sufficient to last for several hours was provided for each suit, so that in case of necessity the wearer could throw off the tubes connecting him with the air tanks in the car. Another object which had been kept in view in the preparation of these suits was the possible exploration of an airless planet, such as the moon.

      The necessity of some contrivance by means of which we should be enabled to converse with one another when on the outside of the cars in open space, or when in an airless world, like the moon, where there would be no medium by which the waves of sound could be conveyed as they are in the atmosphere of the earth, had been foreseen by our great inventor, and he had not found it difficult to contrive suitable devices for meeting the emergency.

      Inside the headpiece of each of the electrical suits was the mouthpiece of a telephone. This was connected with a wire which, when not in use, could be conveniently coiled upon the arm of the wearer. Near the ears, similarly connected with wires, were telephonic receivers.

      An Aerial Telegraph.

      When two persons wearing the air-tight dresses wished to converse with one another it was only necessary for them to connect themselves by the wires, and conversation could then be easily carried on.

      Careful calculations of the precise distance of Mars from the earth at the time when the expedition was to start had been made by a large number of experts in mathematical astronomy. But it was not Mr. Edison's intention to go direct to Mars. With the exception of the first electrical ship, which he had completed, none had yet been tried in a long voyage. It was desirable that the qualities of each of the ships should first be carefully tested, and for this reason the leader of the expedition determined that the moon should be the first port of space at which the squadron would call.

      It chanced that the moon was so situated at this time as to be nearly in a line between the earth and Mars, which latter was in opposition to the sun, and consequently as favorably situated as possible for the purposes of the voyage. What would be, then, for 99 out of the 100 ships of the squadron, a trial trip would at the same time be a step of a quarter of a million of miles gained in the direction of our journey, and so no time would be wasted.

      The departure from the earth was arranged to occur precisely at midnight. The moon near the full was hanging high over head, and a marvellous spectacle was presented to the eyes of those below as the great squadron of floating ships, with their signal lights ablaze, cast loose and began slowly to move away on their adventurous and unprecedented expedition into the great unknown. A tremendous cheer, billowing up from the throats of millions of excited men and women, seemed to rend the curtain of the night, and made the airships tremble with the atmospheric vibrations that were set in motion.

      Magnificent Fireworks.

      Instantly magnificent fireworks were displayed in honor of our departure. Rockets by hundreds of thousands shot heaven-ward, and then burst in constellations of fiery drops. The sudden illumination thus produced, overspreading hundreds of square miles of the surface of the earth with a light almost like that of day, must certainly have been visible to the inhabitants of Mars, if they were watching us at the time. They might, or might not, correctly interpret its significance; but, at any rate, we did not care. We
