llen," said Bentley quickly, "I don't know what's going on here, but I'm sure it's something sinister and awful. Let's take a look at our rooms. If there isn't a door between them which can be left open, then you'll have to spend the night in my room while I remain awake on guard."

"I was thinking of the same thing, Lee," she whispered. "This place gives me the horrors. Barter's association with the apes is a terrible thing."

Hand in hand they stepped to the door Barter had designated as that of Ellen Estabrook's. Bentley opened it cautiously, heaving a sigh of relief to find it empty. He scarcely knew what he had expected. There was a connecting door between the two rooms, open, and they peered into the chamber Bentley was to occupy.

Back they came to her room, to stand before a window which gave onto a shadowed little clearing in the rear of the cabin.

"Look!" whispered Ellen.

There was a single mound of earth, with a white cross set over it, on which was the single word: Mangor.

It might have been a word in some native dialect. It might have been some native's name. It might have been anything, but, whatever it was, it added to the sinister atmosphere which seemed to hang like an evil mist over the home of Caleb Barter.

"That settles it, Ellen," he said. "You'll spend the night in my room."

Ellen retired in Bentley's room, closing the door which led to the adjoining room, and Bentley walked back and forth in the reception room, waiting for Barter to return. When darkness fell he lighted the lamps he had previously located. Their odor caused him to guess that the fuel they used was some sort of animal fat. In the strange glow from the lamps, his shadow on the walls, as he walked to and fro, was grotesque, terrible—and at times a grim reminder of the great apes. It caused him to consider how, after all, human beings were akin to gorillas and chimpanzees. Somehow, now, it was a horrible thought.
