He had not anticipated such a treat when deciding to walk all the way back from Tenafly that morning. And he felt that things were all coming in his direction at a furious rate.
"Fast; eh, Fred?" asked Sid, as he saw the other make a vain attempt to open the door of the mill; through which doubtless the office had been reached in times past, when the neighboring farmers all came here daily to have their grist ground, and to carry home their flour.
"It sure is; I can't seem to budge it," came the reply.
"Wonder if they went in here?" hazarded Bristles, himself giving a fierce though ineffective push.
"We can settle that easy enough," remarked Fred; "by seeing if there are any signs of new footprints here before this door."
"Well, you do take the cake thinkin' up things," muttered Bristles, as he dropped down to examine the soil.
"They're here, all right, Fred!" he announced quickly, in a thrilling whisper.
"Perhaps you even see that shoe print that shows the patch?" asked Fred.
"Right you are," Bristles immediately announced; "just what you told us to watch for. Boys, we've tracked the abductors of our chum to their lair; and now to smash in the door, and jump 'em!"
