286 ILLINOIS STATE HOKTICULTURAL SOCIETY. 



material resources of the State ; but while twenty thousand copies of the 

 Reports of the State Board of Agriculture are published only one 

 thousand of our own are issued. This disproportion seems neither wise 

 nor just ; and I think with proper effort by the Executive Board and 

 members of the Societies we may obtain an appropriation sufficient to 

 publish ten thousand copies annually. 



The Report of the Committee was adopted by an almost unanimous 

 vote. 



REPORT UPON TREASURER'S ACCOUNT. 

 Mr. MiNKLER presented the following report : 



Your committee on Treasurer's Report have examined his accounts 

 and vouchers and find the same substantially correct. 



Signed by the Committee. 



REPORT UPON ENTOMOLOGY. 



Prof. Thomas, being called for, responded, speaking without notes. 



He first spoke of the ten-lined or Colorado potato-beetles, and said 

 they may be held in check by a united effort in any neighborhood in 

 picking and destroying the parent beetles as fast as they appear in the 

 spring. This he claimed would obviate the necessity of resorting to Paris 

 green, against the use of which much objection is made ; but that the 

 parasites and predaceous beetles, especially our little friends, the lady- 

 birds, will probably give us immunity from this pest for a few years. 



He recommended driving the old sort of long, striped potato-beetles 

 from the potato fields, as they are as easily driven as a flock of geese, and 

 two or three times driven off they will stay away. 



He stated that although the Hessian fly had appeared during the past 

 season in considerable numbers, yet there was little cause for fearing their 

 depredations the coming year. He had noticed that unusually warm 

 weather in autumn developed the flies from the chrysalids, and then they 

 were destroyed by cold during the succeeding winter ; and he thinks this 

 is the fact in the present season — that the insects were generally developed 

 by the very warm weather in autumn, and such are probably destroyed by 

 this time. He then gave the history, descriptions and modes of feeding 

 of the European Cabbage-butterfly.

 on pages 242-257 in this volume. — Editor.)
