"See any one under there, Eddie?" he called, assuming that the boy had seen no one or he would have spoken before. "No, I can't make out that there is any one there," replied Ed, "but I am going to make sure." "No, no! Don't go in under there. You will play yourself all out. You can see pretty well, can't you?" Ed got hold of a cross-bar nailed to the piles, and looked long and closely. His eyes having become accustomed to the gloom, it seemed to him that he could see all there was to be seen. "No one there," he announced. "I'm going down now, Pow." "Can you see down there in the dark? You can't. I ought to have thought of that. We can do nothing. I'm a fool." "I can feel around," replied Ed. "That's all I expected to do. If it is anywhere near the pile I'll find it." "But you can't stay down long enough." "Yes, I can." "How are you going to dive down without coming up on the pier?" "Great Scott! I know my business. I'm going to swim down." "Gee, Eddie, you're a wonder!" the Chinaman exclaimed. Ed leaped up almost clear of the water, he was so nimble, turned a half somersault and made his dive after having located the right pile. It seemed to Pow Chow as if he was gone an age, and he had almost given the boy up when he at last appeared. Little did the yellow rascal imagine that he himself would be gone for good before many minutes had passed. "Well, did you find it?" he cried. "No," panted Ed. "I worked on the bottom all around the base of the pile, but I couldn't find a thing." "Too bad! Some one must have got it." "More than likely after all these years. I'm coming out to get my wind." There was a standing ladder near by. Ed swam for it and climbed upon the pier, where he sat down on the stringpiece to rest. "Are you sure you have got the right side of the pier, Pow?" he asked. "Yes, it is the north side. The paper distinctly says so." "Well, that was the seventh pile, all right. I can't believe the case is there." "We ought to try it by daylight," said the Chinaman. "Suppose we ring off and come back in the early morning, Eddie?" "That's what we shall have to do, I guess. Still, one couldn't see much down there anyhow without a light. That's what we ought to have." "Are there electric lights made for the use of divers?" "Sure." "Well, if we don't succeed I'll buy one, no matter what it costs. I don't propose to give this thing up for two or three days anyhow. But you will try it again, Eddie?" he added persuasively. "Oh, yes," replied Ed. "I don't mind trying it again, but say, Pow, does the paper tell which end of the pier to count the piles from?" "Why, no, it don't." "Which end did you count from?" "The outside end." "Suppose I try it at the seventh pile, counting from the inside end?" "Well, that's an idea. Suppose you do." Pow Chow now counted the piles from the other end. No. 7 figured this way came in an entirely different spot. Rested now, Ed dove again.
