Collins, in turn, told how pleased he was to be of service, and the two found a motor-car and started off, taking a road which ran along a level strip of land which lay between the sand and the mountains. They had proceeded a couple of miles when a motor-car appeared in sight just ahead of them, traveling toward the city.

Collins arose in his seat and waved his hand frantically.

"I believe that's Sherman!" he cried. "Sherman's here for a rival steam pump firm, but I'll be good to him, especially as there is nothing doing in the way of trade. Hey, there, Sherm!" he shouted as the two cars drew nearer. "Pull up and give an account of yourself!"

Sherman was a dark-faced, black-haired, bewhiskered fellow of perhaps forty. He was dressed in a dark business suit and wore glasses. The two men talked shop for a moment, and then Collins asked:

"Where have you been?"

"Just out for a ride," was the reply.

"You saw the airship come down?"

"Of come, but I'm not interested in airships."

"Then you haven't been out there?"

"Hardly. It doesn't interest me—this aviation craze."
