It was too much for Paddy. He started for the brook also. The old chuck stopped drinking, and pulled himself together; but Paddy wanted water, not blood. In a moment he had his nose in the brook. There the two lay, not a couple of yards apart, and drank until they could drink no more. The whistlepig was the first out. Slowly and watchfully he waddled away from the brook and toward the stone wall, that refuge of all hunted little animals. Paddy gave a fierce growl, but the water tasted too good, and he stayed for another long drink. Then he darted out after the woodchuck, barking ferociously all the time, as if he could hardly wait to begin the battle again. The woodchuck watched him steadily, ready to stop and fight at any moment. Somehow, although Paddy barked and growled and rushed at his retreating opponent with exceeding fierceness, there were always a few yards between them, until Mr. Chuck disappeared at last down between two great stones in the wall. Then indeed Paddy dashed in, and growled, and tore up the turf, and stuck his nose deep down between the stones, and told the world all the terrible things he would do to that woodchuck if he could only catch him. From the bowels of the old wall, between barks, sounded now and then the muffled but defiant whistle of the unconquered whistlepig. Finally, Paddy, with an air of having done all that could be expected, gave some fierce farewell barks and trotted off toward the farmhouse. Some people claim to have dug woodchucks out of their holes. Personally I believe that it is about as easy to dig a woodchuck out of its hole as it is to catch a squirrel in its tree. They have a network of holes, and have a habit of starting digging on their own account when molested, and sealing up the new hole after them, so that they leave no trace. Once, in company with another amateur naturalist, we tried to dig an old chuck out of its burrow. After first stopping up all the spare holes we could find, the naturalist dug and dug and dug and dug. Then we enlisted two other men, and they dug and dug and dug. After a while we came to a mass of great boulders. Then we pressed into service a yoke of oxen, and they tugged and tugged and tugged. Said digging and tugging and tugging and digging lasted the half of a long summer day. All together, it was an exceeding great digging--but we never got that woodchuck. [Illustration: THE WHISTLEPIG] In September and October the woodchuck devotes all of his time to eating. The consequence is that, by the time the first frost comes, he is a big gray bag of fat. Mr. Woodchuck does not believe in storing up food in his burrow, like the chipmunk. He prefers to be the storehouse. Soon after the first frost he disappears in his hole, and far down underground, at the end of a network of intersecting passages, rolls himself up in a round, warm ball, and sleeps until spring.
