Samuel Madison Hunsicker, "Sam," Mulberry, Ind.
B. S. in M. E.
Thesis—Tests of a Rider Hot Air Pumping Engine Under Varying Discharge Head.
"Sam" has shot hot air so much around the University that it has become a specialty of his, and so he has pursued his favorite line of work, as can be seen from his above Thesis. He is another one of "Jimmie's" prodigies, having succeeded in working a graft early in his Junior year.

Charles Ross Hunsicker, Akron, Ohio. "Hun."
B.S. in M.E. ΑΤΩ. Athletic Association (1) (3) (4).
"Hun" is of the quiet, gentlemanly variety, always unruffled and dignified, when under the possible eye of a prof. But once out with the boys, he is one of the best of "good fellows." During the past year he has added Ladies' Hall to his regular calling list. But in spite of such a handicap, he is finishing strong, right with bunch.

Walter W. Hunzicker, Marion, Ind., "Hunz."
B. S. in Electrical Engineering. ΦΚΣ. Athletic Association (3) (4). A. I. E. E. (4).
"Hunz" has a formidable way of making you believe his fund of information was the only correct and complete set extant, but on closer investigation he is found to be quite harmless. During his Freshman year he learned to make one cope answer for four patterns and this characteristic followed him through college. If he can't find an easy snap he will likely make one, for his originality has never been known to fail him.
