A. Foster D. J. Horn N. F. Johnson Co-Adviser C. A. Triplehom Department of Entomology To Horace R. Burke and Rupert L. Wenzel “The study o f entomology is one o f the mostfascinating ofpursuits. It takes its votaries into the treasure-houses of Nature, and explains some o f the wonderful series o f links whichform the great chain o f creation. It Ic^s open before us another world, o f which we have been hitherto unconscious, and shows us that the tiniest insect, so small perhaps that the unaided eye can scarcely see it, has its work to do in the world, and does it. ” Rev.
