SOME FUETHEE COMMENTS UPON THE WOEK OF LOEENZO EUGENE 



DANIELS. 



BY JUNIUS HENDERSON. 



My good friend Ferriss, in the interesting account of the life, 

 character and scientific work of Mr. Daniels, has briefly men- 

 tioned the principal itenas of his work, but there is opportunity 

 for enlargement upon some of the items. Daniels' work is a 

 good text for a sermonette upon the great value of the non- 

 professional and semi-professional in science. His vocation was 

 agriculture, which furnished the means for carrying on his avo- 

 cation, the collection and study of natural history material. 

 Perhaps there is no branch of natural science that has profited 

 more from the labors of such men than has conchology. There 

 are few strictly professional conchologists or malacologists — that 

 is, men whose living is derived from such work. Therefore, 

 the progress of the science is dependent upon those to whom 

 the work is an avocation, done for the pure love of it, with no 

 thought of financial remuneration. After all, is not that the 

 best reward ? 



Many of us may not realize the extent and value of Daniels' 

 work so fully as we would had his modesty not kept him so 

 much in the background. His mind was a fountain of infor- 

 mation concerning the habits and habitats of snails and methods 

 of caring for material, which information was freely at the dis- 

 posal of his friends. He was usually content to allow others to 

 do the publishing, or to appear only as joint author. I only 

 recall seven papers bearirg his name as the sole author. Prob- 

 ably there are others. In the former account his Minnesota and 

 Montana work was not mentioned. His Minnesota paper 

 covered a field where work was much needed, for the literature 

 of that state was t^cant compared with that of many states. His 

 Montana work, published by Vanatta, was in a vast territory 

 that has only been scratched in a few places by students of 

 MoUusca. His two seasons in Indiana, prior to 1903, forming 

 the basis for nis Catalogue, added 91 to the 184 species and 

 varieties listed for that state by Call, and he has since added
