But they found that one at least of the old foxes had visited the place, for the dry leaves were disturbed; there were marks of sharp teeth on the willows of the cage, and inside the cage were the tails of a couple of wood mice. Unable to get her cubs out of the cage, the mother had brought them food.

It seemed too bad to take advantage of her mother love, but as Horace remarked, all they desired was to restore her to her family; once on the fox ranch, she would be treated like a queen.

They put the cage farther back and piled rocks round it, so that it could be approached only by one narrow path. In the path they placed the trap, and again covered it carefully with leaves.

The cubs had to be left for another night, and the boys had another hard day of waiting. None of them had the heart to try to prospect. Macgregor went after ducks with the shotgun; the others lounged about, and killed time as best they could. They all went to bed early, and before sunrise again started for the den.

It was fully light when they came to the hill over the ravine, and as they sighted the den, a cry of excitement broke from all three of them at once.

From where they stood they could see the cage, and the crouching form of a black animal beside it, evidently in the trap. And over the beast with the dark fur stood a man in a buckskin jacket, with a club raised to strike.

CHAPTER XIII

Fred and Mac, who were carrying the guns, fired wildly at the man at the trap; they took no aim, for their only purpose was to startle him and to keep him from killing the fox. When the shots rang out, the man straightened up, saw the boys rushing down the hill toward him, and dropped his club. Stepping back, he picked up his rifle, and as they dashed up, held it ready to shoot.

Fred gave a whoop when he saw that the animal in the trap was really a black fox; moreover, it was the mother fox. Her black coat was glossy and spotless.
