"If we see any rabbits' tracks we'll know they are on hand."
Dave agreed, and he, Roger, and Phil left the ice-boat, stating they would be back in half an hour.
"All right!" sang out Messmer. "We'll cruise around in the meantime. When we get back we'll whistle for you."
The tramp through the deep snow was not easy, yet the three chums enjoyed it, for it made them feel good to be out in the clear, cold atmosphere, every breath of which was invigorating. They went on silently, so as not to disturb any game that might be near.
"Here are rabbit tracks! " said Dave, in a low tone, after the top of the first hill was gained, and he pointed to the prints, running around the trees and bushes. "Shooting ought certainly to be good in this neighborhood."
From one hill they tramped to another, the base of which came down to the river at a point where there was a deep spot known as Lagger's Hole. Here the ice was usually full of air-holes and unsafe, and skaters and ice-boats avoided the locality.
From the top of the hill the boys commenced to throw snowballs down on the ice, seeing who could throw the farthest. Then Phil suggested they make a big snowball and roll it down.
"I'll bet, if it reaches the ice, it will go clear across the river," said the shipowner's son.
