"I mean the big end of it," said Tom soberly.
The two men glanced at each other and laughed outright. Tom did not quite appreciate what they were laughing at but it encouraged him to greater boldness, and shifting from one foot to the other, he said,
"The thing I noticed specially was how his mouth went sideways when he talked, so one side of it seemed to slant the same as his moustache, like, and the other didn't."
The officers smiled at each other again, but the one quizzing Tom looked at him shrewdly and seemed interested.
"I mean the two ends of his moustache that stuck up like the Kaiser's——"
"Oh, yes."
"I mean they didn't slant the same when he talked. One was crooked."
Again the officers smiled and the one who had been speaking said thoughtfully,
"I see."
Tom shifted back to his other foot while the officer seemed to ruminate.
