Not knowing whether the atmosphere of Mars would prove suitable to be breathed by inhabitants of the earth, Mr. Edison had made provision, by means of an abundance of glass-protected openings, to permit the inmates of the electrical ships to survey their surroundings without quitting the interior. It was possible by properly selecting the rate of undulation, to pass the vibratory impulse from the disintegrators through the glass windows of a car without damage to the glass itself. The windows were so arranged that the disintegrators could sweep around the car on all sides, and could also be directed above or below, as necessity might dictate. To overcome the destructive forces employed by the Martians no satisfactory plan had yet been devised, because there was no means to experiment with them. The production of those forces was still the secret of our enemies. But Mr. Edison had no doubt that if we could not resist their efforts we might at least be able to avoid them by the rapidity of our motions. As he pointed out, the war machines which the Martians had employed in their invasion of the earth, were really very awkward and unmanageable affairs. Mr. Edison's electrical ships, on the other hand, were marvels of speed and of manageability. They could dart about, turn, reverse their course, rise, fall, with the quickness and ease of a fish in the water. Mr. Edison calculated that even if mysterious bolts should fall upon our ships we could diminish their power to cause injury by our rapid evolutions. We might be deceived in our expectations, and might have overestimated our powers, but at any rate we must take our chances and try. A multitude, exceeding even that which had assembled during the great congress in Washington, now thronged New York and its neighborhood to witness the mustering and the departure of the ships bound for Mars. Nothing further had been heard of the mysterious phenomenon reported from the observatories six months before, and which at the time was believed to indicate the departure of another expedition from Mars for the invasion of the earth. If the Martians had set out to attack us they had evidently gone astray; or, perhaps, it was some other world that they were aiming at this time. The expedition had, of course, profoundly stirred the interest of the scientific world, and representatives of every branch of science, from all the civilized nations, urged their claims to places in the ships. Mr. Edison was compelled, from lack of room, to refuse transportation to more than one in a thousand of those who now, on the plea that they might be able to bring back something of advantage to science, wished to embark for Mars.
