"Drop the lead, Carnes!" cried the doctor. With the aid of the detective he operated the electric catches which held the huge mass of lead to the bottom, and the sphere shot up through the water like a rocket. It leaped clear of the water and fell back with a splash. A half mile away the _Minneconsin_ was swinging in a wide circle to head back toward them. They turned their gaze toward the shore.
As they looked a giant arm shot a hundred yards up into the air, twisting and writhing frantically. It disappeared, and another, and then half a dozen flashed into the air. The arms dipped below the surface. A huge black body reared its bulk free from the water for a moment, and the sea boiled as though in a violent storm. The body sank and again the arms were thrown up, twisting and turning like a half dozen huge snakes. The whole creature sank below the waves and the ball tossed back and forth, often buried under tons of water and once tossed thirty feet into the air by the huge waves.
A momentary lull came in the waves. Carnes gave a cry of astonishment and pointed toward the shore. With an effort, Dr. Bird twisted himself in his lashing and looked in that direction. The huge body had again come to the surface, and three of the arms were towering into the air. Grasped in them was a long, black, cigar-shaped object. As they watched the object was torn into two parts and the fragments crushed by the enormous power of the octopus. Again the arms writhed in torment, and then they stiffened out. For a moment they towered in the air and then slowly sank below the surface of the sea.
"The cyanide has worked," cried the doctor, "and in its last agonies the creature has turned on its creator and destroyed him. It is a shame, for Saranoff was a brilliant although perverted genius, and besides, I would have liked to have learned his method. However, I may find something when we open the land end and raid the cave; and really, he was too brilliant a man to hang for murder. Once we open the cave and I get any data that is there, my connection with the case will end. Trailing down the gold and recovering it is a routine matter for Bolton, and one in which he won't need my help."
"What about that creature we saw in the cave, Doctor? Won't it hatch into another terror of the sea like the thing that destroyed the ship?"
