Our bags of zinc filings were stored in a compartment at the bottom of the boat, under our furs and sleeping arrangements. I lifted the latter quickly and drew out some of the ballast. I passed the bags to Gale, who threw them over, one at a time. There was a slight upward pull as each went over, but still the white surface below remained distressingly near. The five hundred feet that still remained of our anchor rope seemed to cover more than half the distance, though this was, of course, deceptive. We continued to throw out our bags of filings until all were gone, and followed them with our supply of acid, which, without the zinc, would be of no value. Minus the means of making gas, our chances of return were, of course, much lessened, but the needs of the moment seemed all important and imperative. As we drew near the flying surface our speed appeared to increase, though in reality it probably slackened.
Our descent now became less rapid. Perhaps because the pressure of the gas was not so great, and also because the lower air was more buoyant. Still, it was not to be denied that we were drawing slowly, surely, nearer to the white plain below. We had not mentioned our predicament to those on the ship, and we said no word now of the impending disaster. We simply huddled down into our fur wrappings and waited, often looking over the side to note our progress, both southward and downward.
Finally, just after noon, it became evident that our anchor-rope would soon touch, and this would presently drag us down.
“How much does that rope weigh?” Gale asked, looking at me.
“About two hundred pounds, perhaps.”
We remained looking at each other, and though not skilled like Ferratoni in such matters, I could read the thought in his mind. The rope, as I have said, was attached to the iron ring below. I would as soon have jumped over at once, as to have attempted to climb over and cut it. As for Gale, he was much too heavy, and not constructed for such work. But we knew we must get rid of that rope.
“Perhaps I can shoot it off,” suggested Gale.
He drew a revolver from one of the compartments, and leaning over, fired repeatedly at the slender mark. But the end below was touching now, and this made it unsteady. He gave up at last, his hands numb with cold.
“Either I am a poor shot, or the bullets won’t cut it,” he said.
“There is no help for it,” I thought. “I must make the attempt and die.”
