"Welcome to Barterville," said the old man. "It has been years since I have seen any of my own kind. People avoid this section of the jungle." "I don't wonder," said Bentley, sighing deeply with relief. "Those brutes would make anybody keep away from here, if they knew about them. I thought they had us for a few minutes. They planned an ambush almost as well as human beings could have done it--but that's absurd of course, merely a coincidence." * * * * * "Coincidence?" snapped the old man, a hint of asperity in his words. "Coincidence? I see you do not know the great apes, sir. I have always maintained that apes could be trained to do anything men can do. I have maintained that they have a language of their own, and even ways of communicating without words, a sort of jungle writing which men of course have never yet learned. I've devoted my life to learning the secrets of the great apes, their life histories, and so forth. I am Professor Caleb Barter!" "Professor Caleb Barter!" ejaculated Ellen Estabrook. "Why I've heard of him! He went on an expedition among the great apes ten years ago and was never heard of again." "I am Caleb Barter," said the old man. "I decided to disappear from the world I knew, to let other fool scientists think me dead in order that I might continue my investigations without molestation. And now I have almost reached the place where I can go back to civilization with information that will startle the world. There yet remains one experiment. Now I hope to make that experiment. No! No! Don't ask me what it is. It is my secret and nobody will ever wrest it from me." Bentley studied the old man. He seemed slightly demented, Bentley thought, but that might be merely the mental evolution of a man who had made a hermit of himself for so many years--if this chap actually were Professor Barter. "Professor Barter," went on Ellen, "was the scientific leader of his day. Others followed where he led. He made greater strides in surgery and medicine, and in unravelling the mysteries of evolution, than anyone else up to his time. Of course I believe you are Professor Barter. My name is Ellen Estabrook, and this gentleman is Lee Bentley. We believe ourselves to be the only survivors of the _Bengal Queen_. Perhaps you can lead us to food and water?" "Yes, oh yes! Indeed. One forgets how to be hospitable, I fear. I am sorry to hear there was a wreck and that lives were lost--but it may mean a great gain to the world of science. I am happier to see you than you can possibly know!" * * * * *
