DicKERSON : John B. Smith in Economic Entomology 2r 



witli farmers and fruit growers ; his mosquito work brought him 

 in touch with local health boards, while the various authorities 

 interested in shade trees called upon him for information con- 

 cerning shade tree pests. On all these occasions and at numerous 

 other times his advice was sought and welcomed because of his 

 good judgment and practical suggestions. 



He not only studied the various species already troublesome 

 in the state, but also kept in mind the dangers of others gaining 

 a foothold there. It was for this reason that a trip was made to 

 Europe in 1900 for the purpose of studying the conditions of 

 economic entomology there. During a later visit there, on account 

 of ill health, he again gave his attention to these matters, especially 

 that of mosquito conditions in Holland. In like manner a number 

 of visits were made to Massachusetts to keep in touch with con- 

 ditions regarding the gypsy and brown-tail moths. 



His work also called for frequent lectures, especially in con- 

 nection with the Farmers' Institutes, and I do not remember a 

 time when he did not speak at the annual meetings of the State 

 Board of Agriculture and State Horticultural Society. In addi- 

 tion to these, he gave many lectures before various associations 

 and organizations. 



Among the numerous societies to which he belonged was the 

 Association of Economic Entomologists, and from the time of its 

 founding in 1889 he was among its most active workers. He 

 became in turn secretary in 1889 and 1890, second yice-president 

 in 1893, first vice-president in 1894, and president in 1895. 



As professor of entomology in Rutgers College he emphasized 

 in his teaching the economic side of the subject and the text-book 

 used was his own " Economic Entomology." 



He was a fluent writer and published numerous papers an eco- 

 nomic insects as well as several papers on Coleoptera and many 

 on Lepidoptera. During the time he was entomologist to the New 

 Jersey Experiment Stations he published twenty-two annual re- 

 ports, covering in all 1,958 pages, some forty bulletins and a like 

 number of circulars. He also edited the department of economic
