"Hercules!" cried Robert, joyfully, from his perch in the tree.
Hercules paused and looked about in surprise, for he saw no one except an ill-looking tramp, who, he was sure, had not spoken to him. He thought he recognized the voice, but was not certain.
"Who is it calls me?" he asked. "Where are you?"
"Here, in this tree."
Then Hercules espied our hero and recognized him.
"Robert Rudd," he cried, in mingled surprise and joy.
"Yes, it is I."
"What are you doing here? I had no idea of seeing you here."
"Nor I you; but I am glad you came along."
