“I know what I’m going to do!” said Jerry in determined tones.

“What?”

“I’m going to find the professor!”

“How can you?”

“I’m going to follow that little stream,” and Jerry pointed to the one up which the scientist had journeyed in the canoe with the negroes.

“But you have no boat. The Dartaway draws too much to take up that creek.”

“I know it. I’m going to walk. I see there is a sort of path along the edge of the stream. I’m going to see where it leads to. I may not find the professor, but I’ll try and find some one who can help us. Maybe I can run across a band of Indians and get some of their remedies. If only Ottiby was here he’d be able to give Bob something to make him well. Will you be afraid to stay here alone with Bob, Ned?”

“No, of course not. But hurry back. There’s no telling what may happen.”

“I’ll bring the professor back with me, or some medicine for Bob,” said Jerry, as he prepared for his journey.
