As they started down to the swamp, Frank exclaimed, suddenly, "Look there, Willy!"
Willy looked, and not fifty yards away, with their ends resting on old stumps, were three or four "hacks," or piles of rails, which had been mauled the season before and left there, probably having been forgotten or overlooked.
Willy gave a hurrah, while bending under the weight of a large rail.
At the spot where the hog-path came out of the thicket they commenced to build their trap.
First they laid a floor of rails; then they built a pen, five or six rails high, which they strengthened with "outriders." When the pen was finished, they pried up the side nearest the thicket, from the bottom rail, about a foot; that is, high enough for the animals to enter. This they did by means of two rails, using one as a fulcrum and one as a lever, having shortened them enough to enable the work to be done from inside the pen.
The lever they pulled down at the farther end until it touched the bottom of the trap, and fastened it by another rail, a thin one, run at right-angles to the lever, and across the pen. This would slip easily when pushed away from the gap, and needed to be moved only about an inch to slip from the end of the lever and release it; the weight of the pen would then close the gap. Behind this rail the acorns were to be thrown; and the hogs, in trying to get the bait, would push the rail, free the lever or trigger, and the gap would be closed by the fall of the pen when the lever was released.
It was nearly night when the boys finished.
They scattered a portion of the acorns for bait along the path and up into the pen, to toll the hogs in. The rest they strewed inside the pen, beyond their sliding rail.
They could scarcely tear themselves away from the pen; but it was so late they had to hurry home.
Next day was Sunday. But Monday morning, by daylight, they were up and went out with their guns, apparently to hunt squirrels. They went, however, straight to their trap. As they approached they thought they heard the hogs grunting in the pen. Willy was sure of it; and they ran as hard as they could. But there were no hogs there. After going every morning and evening for two weeks, there never had been even an acorn missed, so they stopped their visits.
