believe he knows the secret of making the gems," explained Mr. Jenks. "He was one of the men in the cave when I was there before, and he and I struck up quite a friendship; didn't we, Renshaw?"
"That's what, and there ain't no reason why we can't be friends now; that is unless you hold a grudge against me for firing at you. But I only shot in the air, to scare you away. Them's my instructions. I'm supposed to be on guard, and scare away strangers. I'm tired of the work, too, for I don't get my share, and those other fellows, in the cave, get all the money from the diamonds."
Tom Swift uttered an exclamation. A sudden plan had come to him. Quickly he whispered to Mr. Jenks:
"Make a friend of this man if possible. He evidently is dissatisfied. Offer him a sum to show us another way into the cave, and we may yet discover the secret of the diamond makers."
"I will," declared Mr. Jenks, quietly. Then, turning to Renshaw, he added:
"Bill, come over here. I want to have a talk with you. Perhaps it will be to our mutual advantage."
He led the former phantom to one side, and for some time conversed earnestly with him.
