"He ought to be returned to his owner," said Snap. "But how we are going to do it I don't know. I don't care to go back just for the dog."
"Nor I," added Giant. "Let us take him along and bring him back with us when we come."
"If he'll stay with us," came from Whopper. "He may—-if we feed him well," answered the doctor's son.
They let the dog have another cruller and the heads of the fish, and the animal made a meal of them. The boys felt cold and tired and crawled back into the tent to finish their night's rest. Soon the collie came nosing at the opening.
"Come here!" said Giant in a low voice, and instantly the dog nestled down at his side, and there he remained until daylight.
"We can take him in some of our pictures," said the small youth.
"He'll add to the picturesqueness."
"What are you going to call him?" asked Whopper.
"Sphinx."
"And why Sphinx?" asked Snap.
"Because he won't tell us who he is, where he came from, or anything about himself."
