Suddenly John started forward excitedly. “Look,” he cried, “there he is.”

“Where? Where?” demanded Grant.

“Down there in the water. Don’t you see him?”

“Help! Help!” came the call, and John, Fred and Grant sped to the assistance of their comrade. His head showed above the water and he splashed a great deal in an effort to remain afloat. That he was very rapidly becoming weaker, however, was plain to be seen.

“Give me a hand, somebody,” cried George.

“All right, Pop. We’ll be right with you,” Grant reassured him.

George was struggling in the water close to one of the big boulders. Its sides were so steep and high, however, that he was unable to climb out. From his actions it also appeared as if he were keeping himself afloat merely with his hands.

“Get a stick, Grant,” cried Fred. “You can hold it out for him to take hold of.”

“Where is one? Find one, quick!” exclaimed Grant excitedly.

“Here you are,” said John. “This one will do. Take this.”
