"We're not loafing. We have been fishing in the river," said Frank. "Not that it's any of your business, so far as I can see."
"I'll marke it my business," thundered Uncle Dock. "You two fellows had better stay away from here after this. We don't want you hanging around here."
"The river is free," Joe reminded him.
"Keep away from around this mill or I'll make it hot for you. What was that rascal of a boy telling you?"
"We were just talking," replied Frank evasively.
"Well, don't talk to him again. I don't want him mixing up with all the riff-raff of the country and talking to every Tom, Dick and Harry that comes around. I'll thank you to stay away from here after this."
Whereupon Uncle Dock, still grumbling indignantly, went stamping up the slope again toward the mill. The Hardy boys, not a bit alarmed by the outburst, but feeling that they had gained valuable information that day, began to move slowly down the river bank away from the vicinity of the old mill.
