logical concepts of Snodgrass, evidently owing to the understandably 

 different mental interpretations by the individuals. 



Dr. Snodgrass's contributions to science have not been confined to 

 his printed pages. He has given and still is giving freely of his time 

 and technical resources in guiding the efforts of others through per- 

 sonal direction or through correspondence. Students have traveled 

 thousands of miles for the privilege of working under the guidance 

 of Dr. Snodgrass. It is the customary thing to find references by 

 Snodgrass listed in the bibliography of almost every publication deal- 

 ing with arthropod morphology and anatomy, evolution and meta- 

 morphosis, and embryology. In these and publications treating other 

 fields of entomology, illustrations marked "after Snodgrass," "follow- 

 ing Snodgrass," "courtesy of Snodgrass," or "R. E. S." are numerous. 

 Students in unrelated fields often request and receive assistance from 

 Dr. Snodgrass. Currently a young journalist who was inspired by 

 the delightful treatment of aphids in "Insects, Their Ways and Means 

 of Living" (44) is writing an account of the life of an aphid, being 

 privileged to use the prized illustrations signed "R. E. S." 



As a lecturer, "Professor" Snodgrass is often in demand. He is a 

 clear and concise speaker with the ability to present a complex subject 

 in a simple and entertaining manner. Well known to his audiences is 

 his talent for adroitly sketching illustrations on the blackboard. 

 Dr. Snodgrass was a special lecturer in entomology at the University 

 of Maryland from 1924 to 1947. Since then he has given lectures at 

 the University of Minnesota, Cornell University, and the University 

 of Virginia in addition to continuing as guest lecturer at the Univer- 

 sity of Maryland. He has the ability to increase the number of listeners 

 with each lecture as a series progresses. 



During the 1957 series at the University of Maryland, the lectures 

 were attended by students and professors from other departments and 

 colleges on the campus in addition to the Department of Entomology, 

 from neighboring institutions, and from adjacent cities. The current 

 students often found it difficult to keep up with the Snodgrass pace 

 of lecturing and illustrating. Students of former years report that 

 in their day Professor Snodgrass spoke and sketched even more rap- 

 idly than today; the sketches, then as now, did not require any re- 

 touching ; and the only way they could equal the pace was to work in 

 pairs, one copying and labeling the sketches while the other wrote 

 the lecture notes. Professor Snodgrass admits that in those days per- 

 haps he did occasionally sketch with a piece of chalk in each hand. 



In keeping with his rapid, precise thinking and sketching, Dr. Snod- 

 grass writes quickly, "just as the thoughts come to me." Then he
