“Have you fellows heard anything more of that mystery chap?” cried Henry, suddenly changing the subject.
“Not a word,” Tom assured him.
“Well, I have then,” declared Henry triumphantly. “I heard him last night and I got him again to-day just before I called you fellows. He was in the same old place, too.”
“Honest? Say, that is funny!” exclaimed Frank. “What was he saying?”
“Don’t know,” replied Henry, “He was talking some foreign lingo that I couldn’t make out, but I got one word. Bet you couldn’t guess what ’twas—another flower—Oleander this time.”
The boys were so interested in Henry’s news that they had temporarily forgotten their under-water companion until Henry uttered a half surprised exclamation and jumped away from the square opening in the floor over the river.
“Gosh, there he comes!” he cried, as overcoming his
first surprise at a gurgling splash he glanced through the trapdoor and saw the diver’s helmet appearing. “Don’t he look like a regular sea monster?”
A moment later, Rawlins was removing his suit and helmet.
“Did you hear us?” cried Tom the moment Rawlins’ face was visible.
