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 workers 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 1881, 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.
