"Oh, I'd like to know what the monster is made of."

"This investigating seems to be rather dangerous."

"And that makes it all the more fascinating. How

ever, I think it will be well enough to give it a rest for the present."

"We'll go back to the yacht?"

"Yes, and have some dinner. After dinner we can take another whirl at the monster. We must not stay away too long this time, or the people on the yacht will worry about us."

"What shall we tell them?"

"Nothing. It will not do to tell of this adventure."

"But this handkerchief about your head," said Bruce, who was tying it in place; "how will you explain that?"

"Fell and struck my head. I did fall, you know, and my head must have struck the ground down there in that basement. We mustn't let them press us too closely. If they get inquisitive, we must change the subject."
