"Well, I reckon we'll wait till somebody misses us and comes down after us."

"Oh, well, they will do that this morning. Of course they will miss us," declared the Professor, as if the matter were entirely settled.

The expression on Dad's face plainly showed that he was not quite so confident as was the Professor. There was one factor that Professor Zepplin had not taken into consideration. Food! There was barely enough left for a meal for one person. Dad surmised this, so he asked Tad just how much food they had left.

"Our supply," said Tad, "consists of three biscuit, one orange and two lemons."

The boys groaned.

"I'll take the biscuit. You can have the rest," was Chunky's liberal offer. "How about it?"

"You will get a lemon handed to you at twelve o'clock noon to-day," jeered Ned Rector.

"Then I'll pass it along to the one who needs it the most," retorted
Stacy quickly.

"The question is," said the Professor, "is there nothing that we can do to attract the attention of others?"

"I have been thinking of that," answered Nance. "I wish now that we had brought our rifles."
