“Easy enough,” answered Dick. “All you have got to do is to go along the bank an’ strike the ice with an ax, an’ you can tell by the sound where they are. But I fixed all that when I first diskivered this pond. I know jest where the holes are. Now, you go an’ pound on them houses, an’ drive out the beaver.”

The boys accordingly laid down their guns, and commenced an attack on the dwellings of the beaver, when the animals at once plunged into the water under the ice. After every house had been visited, and the boys were satisfied that they had made noise sufficient to drive out all the beaver, they returned to the place where they had left the trapper, and found him engaged in cutting a hole in the ice close to the bank. As the boys came up, he directed one of them to fasten his hunting-knife to a long sapling for a spear, and the other to chop a hole in the bank directly opposite to the one he had cut in the ice.

By the time the spear was finished, an opening had been cut down into the “breathing-hole,” and the hunters discovered three beaver crouching in the furthest corner. Useless thrust his head into the hole, and contented himself with barking at the game; but Brave squeezed himself down into the opening among the beavers, and attacked them furiously. The animals made a desperate resistance, and in a few moments Brave backed out of the hole, with his ears and nose bleeding from several wounds, which showed that the long teeth of the beaver had been used to a good advantage. Frank gazed in surprise at the dog’s lacerated head, and exclaimed:

“There’s something besides a beaver in there.”

“No, I reckon not,” replied the trapper. “Your dog is jest about as keerless as you be, an’ hasn’t got no more sense than to pitch into every wild varmint he comes acrost. You must understand that a beaver can get up a tarnal good fight if he onct makes up his mind to it. An’ when you get one of ’em cornered up, it takes somethin’ besides a ’coon dog to whip him.”

Frank made no reply, and the trapper reached down with his long spear, when one after the other of the beavers were killed and pulled out on the bank. The attack on the houses was then renewed, to drive out any of the animals which might have returned. In the next breathing-hole two beavers were found, but only one was secured, the other making his escape by plunging back under the ice. While they were cutting into the next hole, a large mink suddenly popped out from under the roots of a tree into which the trapper was chopping; and although George made a frantic blow at him with the handle of his ax, he succeeded in getting past him, and started across the pond toward the opposite shore. The boys immediately went in pursuit, George leading the way, and Frank following close behind him, brandishing his spear, and shouting to the dogs, which were close upon the mink’s heels. The little animal made headway through the snow with a rapidity that was surprising; but the long bounds of the dogs were rapidly diminishing the distance between them, and when about half way across the pond, Useless overtook and seized him. The boys increased their speed, fearful that the dog might spoil the skin, which was one of the finest they had ever seen.

“Useless!” shouted George, “get out! Drop that”——

He did not finish the sentence; for suddenly there was a loud crack, and the ice opened beneath him, and he sank out of sight in the cold water. Frank, as we have said, was following close behind him, and at the rate of speed at which he was running, it was impossible to stop; and the trapper, who had been watching the race, and had witnessed the accident with an expression of great concern depicted on his weather-beaten countenance, expected to see Frank disappear also. But the young naturalist always had his wits about him, and summoning all his strength, he sprang into the air, and cleared the hole into which George had fallen, by an extraordinary leap, and landed on the firm ice on the opposite side. George rose almost instantly, for he was an expert swimmer; but his sudden immersion into the cold water seemed to have paralyzed his limbs, and rendered him incapable of action. Frank turned immediately and made a desperate clutch at George’s long hair; but he was too late, for the unfortunate young hunter again sank slowly out of sight. Frank’s mind was made up in an instant, and hastily pulling off his fur cap and comforter, he unbuckled his belt and began to divest himself of his overcoat.

“Take care now, youngster,” exclaimed the trapper, who at this moment came up. “Don’t let George get a hold of you, or you’ll both go down together;” and Dick threw himself on his knees, and stretched his long arm out over the water ready to catch George if he should come up within his reach, while Frank stood upon the edge of the ice, ready to plunge into the water the moment his companion should rise again.

But his intentions were anticipated; for at this moment Brave came bounding to the spot, carrying the mink in his mouth. Understanding, in an instant, that something was wrong, he dropped his game and sprang into the water. At this moment George’s head appeared at the surface, and the dog seized him, when, to the horror of the hunters, both disappeared together. But they arose a moment afterward, and Brave, holding the rescued hunter by the collar of his coat, swam toward his master, and George was drawn out on the ice, in a state of insensibility.
