After setting three traps he led the way to a place where he had left one baited on the occasion of his previous visit to the marsh.

"You see, here's where I set it on the bank," he remarked, "and the chain ran down there to a stake in deep water."

"But it ain't here now, Uncle Jim," said Steve.

"Because a curious and hungry musquash, anxious to reach the bait I stuck on a splinter of wood just above the trap, set it off."

"And then sprang back into the water, because that was his natural way of doing when alarmed, and soon drowned there. Was that the way it worked, Uncle Jim?" asked Max.

The old trapper looked fondly at him and answered:

"Exactly as you say, son. Men who trap these cunning small fur-bearing animals never get tired of studying their habits; and the one who enters most fully into the life and instincts of mink, 'coon, marten, otter, fisher, or even the humble muskrat, is the fellow who succeeds best in his business."

"B-b-but all the m-m-muskrats I ever saw could swim and s-s-stay under w-w-water's long as they p-p-pleased," Toby broke out with.

"That's a mistake," said Trapper Jim. "None of these animals can live under water all the time like a fish. They have to come up to breathe just so often. Beaver have houses made of mud and sticks. The entrances to these are always down below: but you find the tops of all beaver houses above the surface."

"But," said Steve, "I've seen muskrats dive just as Toby says, and waited with a club to have 'em come to the top of the water again; but lots of times I'd have to chuck it up as no good. How did that happen, Uncle Jim?"
