I was at breakfast when my chief engineer entered and saluted. His face was grave, and I thought he was even a trifle paler than usual.

"Well?" I asked.

He drew the back of his forefinger nervously across his brow in a gesture that was habitual with him in moments of mental stress.

"The gravitation-screen generators, sir," he said. "Number one went to the bad about an hour and a half ago. We have been working upon it steadily since; but I have to report, sir, that it is beyond repair."

"Number two will keep us supplied," I answered. "In the meantime we will send a wireless for relief."

"But that is the trouble, sir," he went on. "Number two has stopped. I knew it would come, sir. I made a report on these generators three years ago. I advised then that they both be scrapped. Their principle is entirely wrong. They're done for." And, with a grim smile, "I shall at least have the satisfaction of knowing my report was accurate."

"Have we sufficient reserve screen to permit us to make land, or, at least, meet our relief halfway?" I asked.

"No, sir," he replied gravely; "we are sinking now."

"Have you anything further to report?" I asked.

"No, sir," he said.

"Very good," I replied; and, as I dismissed him, I rang for my wireless operator. When he appeared, I gave him a message to the secretary of the navy, to whom all vessels in service on thirty and one hundred seventy-five report direct. I explained our predicament, and stated that with what screening force remained I should continue in the air, making as rapid headway toward St. Johns as possible, and that when we were forced to take to the water I should continue in the same direction.
