Its huge webbed feet were on the shore now and it darted its head, with open jaws, straight down toward Doctor Dan, who was trying to regain his feet.

CHAPTER XXII.
MUDD ON TOP AGAIN.

Dick and Charley fully realized Dr. Dan’s danger, but what could they do?

The dangerous attempt to snare the Plesiosaurus had not only been a complete failure, but a fearful mistake, for a few seconds later it looked as if Dr. Dan was doomed.

The Plesiosaurus caught him just as it had caught Dick.

It did not bite the Indian, nor even seize him in its terrible jaws, as one might have expected, but with lightning quickness it ran its head under Dr. Dan, and the next Dick and Charley knew it had him twisted in a fold of its long neck, and went waddling off toward the steep, slippery trail down the mountain.

“Fire at him, boys! Fire! Save me if you can!” shouted the unfortunate guide.

Until then the boys had just stood there dumb with the horror of the situation.

How could they fire?

Dick’s revolver had been taken from him by Martin Mudd. Charley had lost his coming down through the Boiling Pot. Dr. Dan himself was the only man who was armed.
