Water Supplies", both being much in demand from out- 

 side Ohio as well as here. 



He held membership in a number of National Scientific 

 Societies, among them Botanical Society of America, 

 American Society Zoologists, American Society of Nat- 

 uralists, Boston Society Natural History and Entomo- 

 logical Society of America. He was Fellow of American 

 Association for the Advancement of Science and a mem- 

 ber of the council, 1915-17. He was a member of the 

 Honorary Societies of Sigma Xi and Alpha Tau Omega. 



His interests were varied — not confined to his Biological 

 work — and he was particularly interested in out door 

 sports for young men, tennis, golf, hiking, fishing, and 

 said "more of that kind of interest would tend to keep 

 the young men in the proper condition morally as well as 

 physically". He was "a great believer in play as well as 

 work". 



He was interested in problems of evolution and many 

 of his published papers had a bearing upon various phases 

 of these fundamental biological questions. A good ex- 

 ample of his originality of thought and method of attack 

 on a problem is shown in his studies of the phenomena of 

 spiral movement in aquatic organisms as exhibited in 

 regions north and south of the equator where the spiral 

 movement has a reverse rotation in forms he observed. 

 The intricate structure of various arthropod groups and 

 their bearing on the questions of their phylogenetic affin- 

 ities formed the subject of a number of morphologic 

 studies. 



He was a successful teacher, beloved by his students, 

 many of them going on to successful careers. Here per- 

 haps was his greatest contribution to science and society — 

 a contribution which cannot be estimated in any statistical 

 or analytical terms. 



Walton had the happy faculty of making friends with 

 people in many different ranks of society and it was re- 

 marked of him by a close friend that he was "an aristocrat 

 and a democrat". He liked to associate with people high 

 up and could also be found in a garage playing checkers 

 with some of the garage men.
