“Give him another, Dick,” cried Charley. “I’m sure my last one hit him, but he never budged.”
Dick let another stone fly and with such good effect that it struck the Plesiosaurus square on the back.
Immediately the monster threw up its head and the water began to boil.
Up came the long neck and the head was thrust angrily out of the pool.
Doctor Dan, with a peculiar cry, flung his huge lasso and it dropped down over the monster’s head.
“Pull! Pull!” shouted the Indian. “We have got him if we can only hold him!”
Dick and Charley were at the other end of the rope and they pulled with all their strength, old P. D. giving out his frightful cry as the rope tightened about his neck.
Suddenly his whole huge body rose to the surface and he darted forward toward the shore.
The rope flew taut and snapped short off close to the post with a suddenness and a force which threw down Dick, Charley and Doctor Dan.
Clara screamed and once more the Plesiosaurus gave its dreadful bellow.
