The next moment he had leaped into it, and casting off the painter, he sculled rapidly toward the pound.

As he reached the upper side of the trap, the porpoise made a quick lunge against the opposite side; but the stout netting and firmly-driven stakes withstood its effort to break through. Seeing his opportunity, Budd pulled in his oar and caught up an old harpoon that lay in the bottom of the yawl, and which was kept there to be used upon the sharks that frequently entered the traps.

It was but the work of a moment to fasten the weapon to the bow-line of the yawl, and then Budd threw it with all his strength at the struggling monster. The sharp point struck the porpoise near the center of its back, and penetrated through the thick hide to the depth of several inches.

"Hurrah! I've got him!" shouted Budd, seizing hold of the bow-line and beginning to haul it in.

Scarcely were the words out of his mouth when the rope was jerked from his hand with a force that sent him over backward in the yawl. Then he heard a crash, and a moment after felt the boat moving through the water a terrific rate of speed.

Crawling up onto his knees and grasping hold of the sides of the yawl, he looked about him. The cetacean had cleared itself from the trap and was going down the bay with the boat in tow. Already the sloop was several rods in the rear, and Judd was shouting to Budd to cut the rope that fastened the yawl to the harpoon, so firmly imbedded in the porpoise's back.

Grasping hold of the sides of the yawl Budd saw that the porpoise was going down the bay at a terrific rate of speed, with the boat in tow.

Holding on to the yawl with one hand, Budd took his jack-knife from his pocket with the other and opened it with his teeth. He then crept along to the bow of the boat and raised his hand to sever the line. That moment there was a movement on the part of his singular steed that led him to change his mind. The cetacean turned and ran obliquely for the shore, and hoping to yet secure the monster, Budd refrained from cutting the rope.

"Look out for the net, first, then come on and pick me up," he shouted back to Judd. "I'll cut the line at the first show of danger."
