was counting on taking you on another trip."

"Well, maybe after we get back from under the ocean,"
agreed Mr. Damon. "I particularly like the cabin
arrangements of the Advance. I think I shall enjoy myself."

He would be hard to please who could not take pleasure
from a trip in the submarine. The cabin was particularly
fine, and the sleeping arrangements were good.

More supplies could be carried than was possible on the
airship, and there was more room in which to cook and serve
food. Mr. Damon was fond of good living, and the kitchen
pleased him as much as anything else.

Early the next morning Tom set out for Atlantis, to meet
Captain Weston at the hotel. The young inventor inquired of
the clerk whether the seafaring man had arrived, and was
told that he had come the previous evening.

"Is he in his room?" asked Tom.

"No," answered the clerk with a peculiar grin. "He's an
odd character. Wouldn't go to bed last night until we had
every window in his room open, though it was blowing quite
hard, and likely to storm. The captain said he was used to
plenty of fresh air. Well, I guess he got it, all right."

"Where is he now?" asked the youth, wondering what sort of
an individual he was to meet.
