He came to the surface within ten yards of the canoe, which was making but feeble progress under Sir Arthur's erratic strokes. Swimming hand over hand, Guy reached the bow and quickly drew himself over the side, just as the pursuing serpent came within seven or eight yards of the stern of the canoe. His original intention to paddle for the island was instantly abandoned. Bidding Sir Arthur work lustily, he snatched up his rifle and took a careful aim at the approaching monster, who was snorting and hissing in a truly frightful manner. The sharp report came at once, producing a thousand echoes through the hollow vault of the cavern, and under cover of the drifting smoke, which for the moment concealed the result of the shot, Guy sprang to Sir Arthur's aid with another paddle. Half a dozen of his powerful strokes brought the canoe within a yard of the shore. A terrific splashing in his rear, as well as the loud shouts of his friends, warned Guy of the imminence of danger. Fairly pushing Sir Arthur out of the canoe into the water, waist deep, he tossed the provisions far out on the island, caught up the guns, and made a frantic leap. He landed on the edge of the sand, and was instantly caught by eager arms, and pulled far up the beach. He turned, to realize with a shudder the narrowness of his escape. Made furious by the bullet hole which Guy had put in his spotted skin, the monster threw himself on the abandoned canoe, which they had been unable to save, and with a sickening crunch it was shivered to a shapeless mass of fragments, under the pressure of the mighty coils. Then, as the serpent flung himself on shore, they realized that it was time to act. A blazing torch in the Greek's hand lit up the scene as Guy cocked his rifle and awaited an opportunity for a shot. It was not slow in coming. As the long neck and head darted forward, Guy fired, and the bullet tore its way through the reptile's throat. There was no necessity for a second shot. The death-agony began right there, and in its convulsive throes the serpent flung himself back into the water, and with a final quiver disappeared in the depths of the lake, leaving a trail of blood on the silvery white sand. With expressions of gratitude for their escape, all hurried down to the broken canoe. "A hundred men could never put this together again," said Guy, as he pulled a couple of floating fragments from the water. The torches and rugs were easily procured, and laid away to dry, but the lamp and the oil-flask could not be found. They were probably at the bottom, but no one cared to dive after them. "That was the closest shave I ever saw," said the colonel. "I gave you both up for lost, and as for that daring act of yours, Chutney, I cannot find words to express my admiration. You saved Sir Arthur's life." Guy modestly made no reply. He calmly pulled on his jacket and shoes, and suggested that they cross the island and take a look at the other serpent.
