dergoing.

"Yes, sir," Dick answered promptly. Then a sudden thought striking
him, he added:

"Perhaps I can make a suggestion, doctor, that is even more immediate
in its nature than yours."

"Then I shall be glad to have it," smiled Laura's father.

"Did you leave that chauffeur to watch your camp?"

"No; he has gone to Five Corners to post the young women's numerous
letters. But the camp doesn't need a guard, does it?"

"It does, as long as Tag Mosher is at large, sir. Harry, won't
you go over to the doctor's camp and stay there until the chauffeur
returns?"

"Yes," agreed Hazelton.

"If you sight Tag, or any other doubtful-looking characters, just
give a yell, and we'll all come over."

"Would that young scamp bother our camp, really?" inquired the
physician.

"Certainly he would," Dick went on promptly. "Mosher, Page, or

In fifteen minutes Dr. Bentley returned.

"Your warning came too late, Prescott," announced Laura's father
cheerily. "Our camp has been visited."

"Tag Mosher?" gasped Prescott.

"Impossible to say," was the smiling answer. "The caller forgot
to leave a card. But someone has cleaned us out of about a dozen
tins of food and some packages of biscuit. It must have been
quite a little load. Just by chance I also happened to think
to look at my medicine case. One vial is missing therefrom."

"What medicine did he take, did you say, sir?" asked Dave Darrin
much interested.

"I believe I didn't say," replied Dr. Bentley. "Perhaps later
on I shall tell you."

"If the thief took only a dozen tins," said Mrs. Bentley, "there
is food enough left so that we needn't worry about immediate famine.
And we have two cars, either one of which may be despatched to
bring further supplies."

"Tag is
