690 BIBLIOGRAPHY 



at small cost from The Superintendent of Documents, Wash- 

 ington, D. C. Some titles are out of print, but such papers 

 are usually obtainable in revised form in later publications. 

 A very excellent library of entomology might be formed 

 entirely of publications in the several series listed above. 



2. Publications of the various state agricultural experiment 



stations. 



Each one of the several states maintains one or more 

 experiment stations. These issue bulletins from time to time 

 and much of the best information available on injurious 

 insects is contained in these bulletins. Subjects of local 

 interest are likely to be more fully treated in the state bulletins. 



These bulletins may always be obtained free upon applica- 

 cation so long as the supply lasts. 



3. State publications issued by agencies other than the State 



Agricultural Experiment Stations. This will include the 

 State Departments of Agriculture which issue reports 

 from the state entomologists. Much valuable informa- 

 tion will be found in these reports which is not available 

 elsewhere. Especially extensive reports of this nature 

 are issued by the State Entomologists of New York, 

 Illinois, Minnesota, Missouri and Indiana. 



Other state agencies issuing publications which include 

 entomological subjects are State Horticultural Boards or Com- 

 missions, as in Florida and California, State Entomological 

 Commissions and State Educational Departments. 



State publications can usually be secured free upon appli- 

 cation. 



4. The Journal of Economic Entomology. 



Much of the newest work in economic entomology is 

 reported first in this journal and many articles are available 

 there only. It issues six numbers annually and the subscrip- 

 tion price is low. It may be obtained through Mr. A. F. 

 Burgess, Melrose Highlands, Mass. 



5 General texts. 



Fundamental information on entomology is obtained best 

 from some one of the standard texts, of which there are sev-
