"Teach them all there is to know." "I'll teach them all I know myself," answered the aviator.
That evening the boys could talk of nothing but aviation, and many were their plans for flights in the _Dartaway_.

All wanted Captain Colby to tell them if the biplane could carry three persons.
"I hardly think so," answered the aviator.

"It will carry two, though, that I am sure of." "Well, if it will carry two men it ought to carry three boys," insisted Sam.
"The best way to find out is to try it," went on the captain.

"So long as you run with care, nothing can happen to you because of the extra load.

Of course if the weight is too heavy the biplane won't go up, or if it does, it won't stay up." The following day came a telegraph message from one of the old Putnam Hall pupils, Hans Mueller.
