I taxied in close to shore and moored the ship to a buoy, while the men launched a dory and rowed out to get me. I had been absent less than a week, most of which had been spent in Guaymas awaiting the expected letter from Tarzana, but so exuberantly did they greet me, one might have thought me a long-lost brother returned from the dead, so dreary and desolate and isolated is Guadalupe to those who must remain upon her lonely shores for even a brief interval between contacts with the mainland.

Perhaps the warmth of their greeting may have been enhanced by a desire to conceal their true feelings. We had been together constantly for months, warm friendships had sprung up between us, and tonight we were to separate with little likelihood that they and I should ever meet again. This was to be my last day on earth; after today I should be as dead to them as though three feet of earth covered my inanimate corpse.

It is possible that my own sentiments colored my interpretation of theirs, for I am frank to confess that I had been apprehending this last moment as the most difficult of the whole adventure. I have come in contact with the peoples of many countries, but I recall none with more lovable qualities than Mexicans who have not been contaminated by too close contact with the intolerance and commercialism of Americans. And then there was Jimmy Welsh! It was going to be like parting with a brother when I said good-bye to him. For months he had been begging to go with me; and I knew that he would continue to beg up to the last minute, but I could not risk a single life unnecessarily.

We all piled into the trucks that we had used to transport supplies and materials from the shore to the camp, which lay inland a few miles, and bumped over our makeshift road to the little table-land where the giant torpedo lay upon its mile long track.

“Everything is ready,” said Jimmy. “We polished off the last details this morning. Every roller on the track has been inspected by at least a dozen men, we towed the old crate back and forth over the full length of the track three times with the truck, and then repacked all the rollers with grease. Three of us have checked over every item of equipment and supplies individually; we’ve done about everything but fire the rockets; and now we’re ready to go—you are going to take me along, aren’t you, Car?”

I shook my head. “Please don’t, Jimmy,” I begged; “I have a perfect right to gamble with my own life, but not with yours; so forget it. But I am going to do something for you,” I added, “just as a token of my appreciation of the help you’ve given me and all that sort of rot. I’m going to give you my ship to remember me by.”

He was grateful, of course, but still he could not hide his disappointment in not being allowed to accompany me, which was evidenced by an invidious comparison he drew between the ceiling of the Sikorsky and that of the old crate, as he had affectionately dubbed the great torpedolike rocket that was to bear me out into space in a few hours.

“A thirty-five million mile ceiling,” he mourned dolefully; “think of it! Mars for a ceiling!”

“And may I hit the ceiling!” I exclaimed, fervently.

The laying of the track upon which the torpedo was to take off had been the subject of a year of calculation and consultation. The day of departure had been planned far ahead and the exact point at which Mars would rise above the eastern horizon on that night calculated, as well as the time; then it was necessary to make allowances for the rotation of the earth and the attraction of the nearer heavenly bodies. The track was then laid in accordance with these calculations. It was constructed with a very slight drop in the first three quarters of a mile and then rose gradually at an angle of two and one half degrees from horizontal.
