"I want you to blow up this submarine, Keith," he said quickly. "A favor to me."

He cut Wells short when the commander started to interrupt. "Wait! Let me finish," he pleaded. "I want to explain. I'd been hoping—but never mind that.... Keith, a while ago I managed to work loose. I lost my head completely and tackled these devils. It was a foolish thing to do; they overcame me, naturally. But, in the struggle, they tore my sea-suit."

"What!"

"Oh, just a tiny tear, or I wouldn't have lasted till now. But a leak all the same—in the right leg. Since then I've been gripping the edges of the fabric as tightly as I can—but I couldn't keep the water inside this ship from seeping through. It came in slowly at first, then faster as my hands grew numb. It's up to my neck now, Keith ... and—it won't be long! I've just a few minutes left...."

"No!" roared Keith in a great rush of emotion. But Hemmy's eager voice came right back:

"Oh yes, you must! It would be a mercy to kill me, Keith."
