"Very well; I don't wish to leave it behind me for some one to discover, and I can't take it along. We will send it off for a long trip, and if it falls back it will be into the lake."
"Wait a moment, then! Let's put a good-bye message in it;" and so saying I took an old envelope from my pocket and wrote on the back of it with a pencil in a bold hand: "Farewell to Earth for ever!" Laughing, I put this inside and closed the lid.
Then the doctor turned down a thumb-screw upon a little wire which connected the poles, and stepped back quickly. Presently the forward end began to rise slowly, until it stood upright, but there it hesitated. The doctor stepped forward and gave the thumb-screw a hard turn down, and the model lifted immediately, rising at first gradually, but soon shooting off with the whizz of a rocket over the lake. We watched it as long as we could distinguish its dark outline.
"It will go a long way," said the doctor. "I have never seen it make so good a start. It will lose itself in the lake far from here."
We fastened up the front window and the port-hole, and started back to Whiting, where the doctor was to remain all night, so as to begin work early in the morning. Presently, as we walked along, the doctor said,—
"Well, Isidor, now you have seen a practical demonstration of the elementary working of the projectile. You also have some idea of all there is to be discovered up yonder in the red planet. You are the most interested in making and profiting by those discoveries. I want you to consent to go along."
"Haven't you secured a companion, then?" I inquired.
"Yes, I have a friend, a countryman of mine here, who will go wherever I say. He appreciates neither the risks nor the opportunities of the trip, still he will take my word for everything. Yet if I ask him to go I take the responsibility of his life as well as my own. He is not a suitable man, however, and I have really relied on you to come," he insisted.
"My dear doctor, I have every faith in you and in the projectile, and I prophesy a most successful trip. I should like nothing better than the adventure; but you must not count on me; I could not leave my business. There's a fever in my blood that thirsts for it!"
"Your business, indeed! You will never really amount to much till you have left it. It's half a throw of dice and the other half a struggle of cut-throats!"
