utter,"
finished Andy. "Now that's a purely scientific problem, Dan, not an
ordinary question. You want to take three pounds of oleomargarine and
divide them by two pounds of unadulterated butter, then----"

"For gracious sake! has that boy gone crazy?" cried Dan Soppinger in
despair. "I come over here and ask an ordinary question in history----"

"How do we know it's an ordinary question in history?" broke in Randy.
"The five, ten and fifteen sounds like a problem in higher arithmetic."

"Say, Dan, just forgive me for what I said, and I'll send you the answer
day after yesterday on a postal card," announced Andy mournfully. "And
I'll prepay the postage, too. Now, be a good boy, Son, and run along,
and maybe some time papa will buy you a lemon stick," and at this
remark there was a general laugh, in the midst of which Dan Soppinger
threw up his hands, turned and left the room.

It was several days after the hunting expedition, and the Rover boys had
settled down once more to their studies. This was the off hour in the
evening, and, as was usual, a number of their friends had dropped in to
see them.

"Only three weeks more to the winter holidays," announced Gif presently.

Gif," was the reply.

During the days that had gone by since the hunt, the Rover boys had had
several little differences with Professor Lemm. The teacher had spoken
to Colonel Colby about their coming in late, but the master of the Hall
had passed this matter over as being of no importance, somewhat to Asa
Lemm's chagrin.

"Oh, how I love that man!" had been Andy's comment.

The weather had remained clear, but on Thursday of that week came
another fall of snow, and by Friday this was in good condition for
sleighing.

"I wonder if we can't get up a sleighing party for Saturday afternoon
and take out some of the girls from Clearwater Hall?" said Jack.

"We ought to be able to get some sort of box-sled down at the Haven
Point livery stable," answered Randy. "Suppose we call the liveryman up
on the 'phone and see what he has to say, and then call up the girls?"

This was done without delay, and, as a result, it was arranged t
