The boys stopped when they reached the front of the hut.
"Hello, Rabig!" they greeted him.
"Hello!" responded Rabig, still keeping up his pacing.
"Right on the job, I see," remarked Bart, pleasantly enough.
"Your eyesight's mighty good," replied Nick sullenly.
"Yes," Bart came back at him, "I can see a bit of white paper from quite a distance."
Rabig gave a sudden start.
"What do you mean by that?" he demanded.
"Nothing special," replied Bart carelessly. "What should I mean?"
"By the way," put in Tom, "you'd better tuck your handkerchief in a little more tightly or you'll lose it. It looks as though it were almost ready to drop out."
