the economic relations of birds will long remain the model for later 
students, this book is gratefully inscribed.”” A further tribute is found 
in a review by Dr. Elliott Coues in the Bulletin of the Nuttall Ornitho- 
logical Club (1883). The article considered was by S. A. Forbes and 
entitled: ““The Regulative Action of Birds upon Insect Oscillations.” A 
two-page review begins: ‘Our best authority upon the insect food of 
birds has continued his observations upon the subject.” The final 
_ paragraph of the review is as follows: “We trust Professor Forbes will 
not desist from his good work. Such exact data as these are just what 
is required for the solution of the general problem which 1s offered by 
the relation of the bird-world to agriculture.” 
In a six-page article in Volume VI of the above named Bulletin (1880) 
J. A. Allen discusses literature dealing with the relation of insectivorous 
birds to man and gives chief attention to the papers of Doctor Forbes 
and one paragraph is as follows: “‘To Professor Forbes 1s due the credit 
of not only first directing attention to the subject, but of first institut- 
ing systematic research respecting the relation of birds to predacious 
and parasitic insects.’’ Foreign recognition of the value of these con- 
tributions is found in reviews of some of his papers and in the award of 
first-class medal of the Societe d’Acclimatation de France for scientific 
publications (1886). 
In 1882 Doctor Forbes was appointed State Entomologist and in 
1884 the range of his duties became still more complex and his oppor- 
tunities for public service still further increased by his appointment as 
Professor of Zodlogy and Entomology at the University of Illinois at 
Urbana. This appointment involved the removal of the headquarters 
and equipment of the office of State Entomologist and of the Illinois 
State Laboratory of Natural History from Normal to Urbana and also 
involved the planning, supervision and much of the instruction in the 
- courses offered in Zodlogy and Entomology. The multitudinous duties 
in these three lines of service, as State Entomologist, Director of the 
Natural History Survey work and Professor of Zoology and Entomology 
were successfully performed during a period of 25 years and then in 
Ig09 a separate Department of Entomology was organized and Profes- 
sor Forbes was made head of this department and relieved of respon- 
sibility for the work of the Department of Zoology. During the period 
1888-1905 he also served efficiently as Dean of the College of Science. 
In 1917 a reorganization of the work of the State Laboratory of 
Natural History and of the State Entomologist led to the merging of 
the activities of the two into one organization, the Division of the 
Natural History Survey of the State of Illinois, Department of Regis- 
tration and Education, with Doctor Forbes as Chief of the Division. 
In 1921 he was relieved from responsibility for the work of the Depart- 
ment of Entomology and thus permitted to give more attention to the 
work of the Natural History Survey in which he is still actively engaged
