His mother laughed.

"You must have a good sleigh ride, too," she put in.

"I draw the line on a sleigh ride if we have to go with that horse that brought us up from the station," announced Bob.

"Me, too!" Van echoed.

"It would take you the entire ten days to get anywhere and back if you went sleighing with the Admiral," said Mr. Carlton.

Every one smiled.

"I'd advise your seizing upon the first clear day for your Monadnock tramp," Mr. Carlton continued. "You'd better make sure of good weather when you get it. It won't make so much difference with your other plans; but for the mountain trip you must have a good day."

"I do want Van to get the view from the top if he makes the climb," Bob answered.

So the chat went merrily on.

Yet despite the gaiety of the evening and Mr. Carlton's evident interest in the boys' holiday schemes Bob more than once caught his father furtively studying Van's profile. Obviously something either puzzled or annoyed him. There was, however, no want of cordiality in his hearty goodnight or in the zest with which he advocated that if the next morning proved to be unclouded the two lads better make certain of their mountain excursion. He even helped lay out the walk and offered many helpful suggestions. Bob's uneasiness lest his father should not like his chum vanished, and when he dropped into bed the last vague misgiving took flight, and he fell into a slumber so profound that morning came only too soon.
