We cleared away the brush behind them, and fastened a pole from one tree to the other, some eight feet from the ground. Then we cut a number of long poles, and laying one end of them on the cross pole, and the other on the ground, made the skeleton of a lean-to hut. McKinstry had built a fire. He threw the hedgehog into it, and let him stay till the quills were well singed. Then he pulled him out and tied a string to him. "What are you doing that for?" "For a scent. I'll show you." McKinstry and I set out with the traps and bait, leaving our companions to cut fir boughs, with which to thatch the roof and sides of the hut, and make a bed. He held the hedgehog up by the string, and we walked down to the pond, and along the edge of it. "There's tracks enough, Ben. Must be game here. I'll scoop out a little snow, and you open the trap, and lay it in the hollow. Now, we'll cover it with twigs and leaves, to hide it. Cut up a rabbit, and lay the pieces on the twigs for bait. Bring me that log over there, and I'll fasten it to the chain for a clog. He'd gnaw, or pull his foot off, if we tied the trap to a tree. He'll haul the clog along, but he won't get many miles with it. Now we'll drag the hedgehog round, and the burnt quills will make a strong scent on the snow. That will do. We'll go on and pull the hedgehog through the snow behind us. When the animals strike that trail, they'll be apt to follow it to a trap." We set all our traps along the edge of the pond, at quite a distance from each other; and at the last trap, cut up the hog, and baited the trap with it. When we got back to camp, we found the roof and sides of the hut well thatched with boughs, and a good thick layer of them on the ground for a bed. The boys had collected a lot of wood, and piled it up near by. In front of the hut was a fire, at which Martin was baking some rye and Injun bread, and frying a large mess of pork. When we had eaten our supper, it was solid comfort to sit in our hut, after our long day's work, to look at the fire blazing in front, to feel the heat, and watch the smoke curl up through the tree. On the further side of the fire they had built up a wall of green logs, so that the heat was thrown into the hut. We were snug and warm. [Sidenote: JOHN McNEIL]
