Thereupon young Prescott fell to describing the trip that he, Dave Darrin, Greg Holmes, Dan Dalzell, Tom Reade and Harry Hazelton had mapped out for themselves.

"Just for pleasure?" asked Mr. Luce.

"No, sir; for training. We all hope to make the football team this fall. We're all of us in pretty good shape, too, I think, sir; but we're going out on this training hike to see if we can't work ourselves down as hard as nails."

"I'd like to go with you," nodded the sub-master.

"Can't you do it, sir?" asked Dick eagerly, for Mr. Luce was a favorite with all the boys.

"Unfortunately, I can't," replied the submaster. "I'm expected at home. My mother and sister claim me for this month. But I wish I could go, just the same."

"You would be most welcome I assure you, sir," replied Dick warmly.

"Thank you, Prescott," returned Mr. Luce with a smile. "I appreciate your invitation and regret that I cannot accept it."

The conversation again turned to the subject of the coming football season, and an animated discussion ensued, as Sub-master Luce was an enthusiastic advocate of football.

Suddenly, Dick, glancing ahead out of the window, turned pale. Without a word of explanation he sprang from his seat and made a bound for the nearer car door, the rear one.
