 tention of entomologists to the possibilities of this phase of economic 

 work. 



The rewards of honor that came to Professor Snow in his long, 

 active life of student, teacher, university president and represen- 

 tative citizen need hardly be mentioned. From Williams College, 

 his alma mater, he received an honorary Ph. D. in 1881, and from 

 Princeton University the degree of LL. D. in 1890. His conspicuous 

 part in encouraging local interest in natural history was recognized 

 by his election five times as president of the Kansas Academy of Sci- 

 ence. His personal acquaintanceship among the people of the state was 

 extraordinarily large, and his place in the respect and affection of 

 these people was evinced time and time again by public recognition 

 of one kind and another. In the days of the Populist control of the 

 state administration, it is probable that it was only Snow's personal 

 strength with the people that saved the university from such serious 

 interference as befell the State Agricultural College. The dedication 

 of the beautiful university building of natural history as Snow Hall, 

 and the building, by special legislative action and appropriation, of 

 a residence for his inhabitancy for life, were characteristic recogni- 

 tions of his value to the university and the state. 



But I must not give my pen more rein. ]My personal feelings I 



have given no rein at all. As student, assistant, colleague and 



intimate friend of Francis H. Snow for twenty-five years, I have in 



my mind and heart such a Avealth of dear memory that I do not trust 



myself even a word or phrase of personal appreciation. If I should, 



it would be too extravagant for publicity, to insufficient for my own 



satisfaction.

Manual of North American Diptera, by Samuel W. Williston, p. 

 1-405. 161 figures. 1908. James T. Hathaway, Xew Haven. 



The Diptera, x)r two-winged flies, are rapidly coming to the front on ac- 

 count of numerous forms previously almost ignored and now recognized as 

 of great economic importance. The author has laid a heavy obligation on 

 all entomologists in turning aside from other lines of work, to condense into 

 this useful manual the experience of a lifetime. The value of the publica- 

 tion has been greatly increased by the cooperation of such Dipterists as Al- 

 drich, Coquillett, Townsend and others. The large series of illustrations
