PREFACE 



This volume, tvhich has been -made possible by the gen- 

 erosity of the Trustees of Kenyon College, was originally 

 intended to contain Dr. Walton's collected publications, 

 but ttvo important studies made for the Ohio Biological 

 Survey tuere found to be too long for inchision. Also 

 omitted, because of their subject-matter, are an article 

 ^'Fraternities and Scholarship'^ and a newspaper letter on 

 the Flood. On the other hand, a youthful letter of ad- 

 vice about army worms and a proposed etymology of 

 caribou have been rather arbitrarily included. 



Reproduction of the figures which accompanied the 

 original articles proved to be impossible. Parenthetical 

 references to them have been cut out, but not references 

 which form part of the text. My hope is that most of the 

 remaining inconsistencies are referable to the original pub- 

 lished source. 



At the time of his death. Dr. Walton was preparing a 

 collection of his papers; his bibliography has been used as 

 a basis for mine. It was not, however, complete, and the 

 additions I mve to Dr. Herbert Osborn, director of the 

 Ohio Biological Survey and a dear friend of Dr. Walton. 

 I wish to thank Dr. Osborn for his invaluable help and 

 advice in preparing this volurjte, and for his kindness in 

 writing the Introduction to it.
