take up in September."

"Oh, I dare say you'll get a very fair smattering of engineering,"
assented Tom. "It's nothing like the real practice that we get,
though, out in the field with the survey and construction parties.
I guess you fellows, after your grind in the High School, found
West Point math. pretty easy, didn't you?"

Dick laughed merrily before he answered.

"Tom, the math. that a fellow gets in High School would take up
about three months at West Point. How are you on math., now?"

"Oh, not so fearfully rotten," replied Reade complacently. "Harry
and I have had to dig up a lot of new math. since we've taken
on with an engineering corps in the field. Harry, trot up some
of the kind of mathematics that we have to use."

"Wait a moment," put in Dick. "Greg, sketch out an easy one from
the math. problems we have to dig into at West Point. Give 'em
something light from conic sections first."

Cadet Holmes sketched out, on the back of an envelope, the
demonstration of a short problem.

Tom and Harry looked on laughingly, at first. Then their eyes began
to open.

"Do you really have to dig up that sort of stuff at West Point,"
demanded Reade.
