The Chinaman shook his head.

“Not hurt, no,” he assured them. “I come thlough without a scratch, as far as I know. But I velly much nervous.”

“No wonder,” said Bob. “That wreck was enough to shake anybody’s nerves.”

Bob and Joe remained at the scene for several minutes. Then, as they realized that it was nearly seven o’clock, they started to leave. But at that moment the Chinaman called them back.

“Before you go I want that you make me a promise,” he said.

The youths looked inquiringly.

“I want that you promise you come to my shop tonight. Will you come?”

The boys were not a little surprised. They wondered what the man’s object was in asking them to visit him.

“Yes,” said Bob at last, knowing that his chum would also consent. “We’ll come. But where is it? And just when do you want us?”

Bob wrote what the man told them on a piece of paper. The latter asked that they be there at nine o’clock, although just why they could not guess.
