INSECTS IN RELATION TO MAN 405 



State Experiment Stations. The organization of State 

 Agricultural Experiment Stations in 1888, under the Hatch 

 Act, gave economic entomology an additional impetus. At 

 present, all the states and territories, except Indian Territory, 

 have an experiment station, and in a few instances two or even 

 three; while there are stations in Alaska, Hawaii and Porto 

 Rico. These stations, often in connection with state agricul- 

 tural colleges, maintain altogether over forty men who con- 

 cern themselves more or less with entomology, and have issued 

 a great number of bulletins upon injurious insects. These 

 publications are extremely valuable as a means of disseminat- 

 ing entomological information, and not a few of them are 

 based upon the investigations of their authors. Especially 

 noteworthy as regards originality, volume and general useful- 

 ness are the publications of Slingerland in New York, Smith 

 in New Jersey, Webster in Ohio (formerly), Hopkins in West 

 Virginia, Gillette and Osborn in Iowa and Gillette in Colorado. 

 The reports that Lugger issued in Minnesota, though compiled 

 for the most part, contain much serviceable information, pre- 

 sented in a popularly attractive manner. 



While these \vorkers have been conspicuously active in the 

 publication of their investigations, there are many other sta- 

 tion entomologists who devote themselves altogether to the 

 practical application of entomological knowledge, and whose 

 work in this respect is highly important, even though its influ- 

 ence does not extend beyond the limits of the state. 



The U. S. Entomological Commission. This commission 

 founded under a special Act of Congress in 1877 to investigate 

 the Rocky Mountain locust, consisted of Dr. C. V. Riley, Dr. 

 A. S. Packard and Rev. Cyrus Thomas, remained in existence 

 until 1 88 1, and published five reports and seven bulletins, all 

 of lasting value. The first two reports form a most elaborate 

 monograph of the Rocky Mountain locust; the third report 

 includes important work upon the army worm and the canker 

 worm ; the fourth, written by Riley, is an admirable volume on 

 the cotton worm and boll worm; and the fifth, by Packard, is 

 a useful treatise on forest and shade tree insects.
