ational institutions. The good seed sown in Pennsylvania was 
destined to bear additional fruit and in 1859 the American Ento- 
mological Society was founded. 
It lacked funds to carry on the work, but what it needed in this 
respect, it made up in energy and the devotion of its members. 
The Proceedings were put into type and printed by the members, 
and it produced or aided some of the greatest of the world's entom- 
ologists. 
Drs. Le CONTE and HORN did splendid work in the Coleoptera 
and E. T. CRESSON was the pionneer systematist in the Hymeno- 
ptera. He was virtually the founder of the Society and still takesan 
active interest in its work and welfare. This Society and its public- 
ations have made a great impression on the study of entomology 
in America. 
The limits of this paper will not permit any further detail as to 
what has been done in Pennsylvania, which may be called the 
cradle of entomology in America. There were developed other 
centres in various parts of the country and it is necessary to refer 
briefly to these. 
In 1841 Dr. THADDEUS WILLIAM HARRIS, of Cambridge, Mass., 
published his work entitled. « A Treatise on some of the Insects 
Injurious to Vegetation». It formed one of the scientific reports 
published by the State. His directions from the Governor of the 
Commonwealth were as follows... « It is presumed to have been a 
leading object of the Legislature, in authorizing this Survey, to 
promote the agricultural benefit of the Commonwealth, and you 
will keep carefully in view the economical relations of every sub- 
ject of inquiry. By this, however, it is not intended that scientific 
order, method, or comprehension should be departed from. At the 
same time, that which is practically useful will receive a propor- 
tionately greater share of attention than that which is merely 
curious; the promotion of comfort and happiness being the great 
human end of all science ». 
This valuable work was extensively used and played an import- 
ant part in the education of more than one of our present day 
workers in entomology and it passed through a number of edi- 
tions. 
An important center was developed in the far west, when 
Dr. HERMAN BEHR left Germany for San Francisco and began his 
papers in the « Proceedings of the California Academy of Sciences »
