"Are you sure you didn't drink anything else?"
"You know I'm a strict temperance man."
"I know you are," said Tom; "but I thought maybe you might have a cold, or something like that."
"No, I haven't taken a thing. I did have a drink of soda water before I came on duty, but that's all."
"Where'd you get it?" asked Tom.
"Well, a man treated me."
"Who?"
"I don't know his name. He met me on the street and asked me how to get to Plowden's hardware store. I showed him—walked part of the way, in fact—and when I left he said he was going to have some soda, and asked me to have some. I did, and it tasted good."
"Well, don't go to sleep again," suggested Tom good-naturedly. "Did you hear anything at the side window a while ago?"
"Not a thing, Mr. Swift. I'll be all right now. I'll take a turn outside in the air."
