insects are often saturated, and much stronger than the mixture given, 
for if the material is broadcasted or sown in the rows, each drop of 
water carries with it all that it can dissolve, and as the moisture evap- 
orates the mixture becomes just as strong as it is possible to be, and 
of course the insecticide effect is intensified. 
I will close by simply referring to the fact that the phospates have 
no insecticide value so far as my experience has gone — not even the 
odorless phosphate, which has been put upon the market with the 
usual nostrum circular claiming that it would kill everything. 
This paper was discussed by Messrs. Hopkins and Webster. 
Mr. Hopkins thought it was a question as to whether the fertilizers 
really kill insects, or by giving plants increased vigor enable them to 
outgrow injuries. He had observed in his practice on the farm that 
the use of stable manure on sod infested with white grubs and wire- 
worms had the effect of producing a good crop of corn when plowed 
under, while on adjoining land not fertilized the attack of these insects 
was very destructive. 
Mr. Webster had no doubt that fertilizers increased the vigor of 
plants but thought that Mr. Smith had not demonstrated that they des- 
troyed or drove away the insects'. 
On motion the association adjourned to meet at 9 o'clock, a. m., 
August 15.

The association met in room 24, Science Hall, at 9 o'clock, a. m.,

Mr. Webster moved that Messrs. Edw. H. Thompson, of Tasmania, 
and R. Allen Wight, of Auckland, New Zealand, be elected foreign 
members of the association. It was carried. 
The secretary stated that he had received in reply to invitations 
sent to foreign entomologists letters of regret for inability to attend 
our meeting from the following: H. du Buysson, of France; F. A. Mar- 
shall, Cornwall, England; Dr. J. Ritzema Bos, Wageningen, Nether- 
lands; Dr. H. Hollrung, Halle, Germany; Edw. H. Thompson, of Tas- 
mania; R. Allen Wight, Auckland, New Zealand; Dr. 0. C. Vinton, of 
Korea, Asia ; Natalis Rondot, Lyons, France ; Robert Newstead, Ches- 
ter, England; Miss Eleanor A. Ormerod, St. Albans, England. 
An extract from Miss Ormerod's letter was read containing compli- 
mentary words concerning the work of the association and its mem- 
bers. 
The following paper was then read :
