“Jerry!” he shouted. “We’re headed square into a monstrous storm!”

“Absolutely.”

“We’d better turn back.”

“May be the end of ’em,” he grumbled. And for the life of him, he could not help feeling sorry.

“May be the end of us, too.” He took a good grip on himself. “I’ll do my level best! No one could do more.”
