 thii'teen I)iicl)es> a|)|)l('-trecs. with the following insecticides, for the 

 codliiiii" niolh : A (\\-y luixtui'c of Paris o-rceii and })laster (1 poinid of 

 (he foniicr lo Kmi pounds of the latter) ; a solution of London puri)l(' 

 (1 pound to I'J.s oallons of water): carholi/ed plaster (1 pint of 

 cruile ("irl)olic acid to IMO pounds of connnon land plaster). Four 

 trees were used as checks. /'. , ., were not treated with any insecticide. 

 When the results were reckoned up in. the orcjinary Avay it a])peared 

 tha.t •■ tile Paris areen and plaster application saved Dl per cent, the 

 London ])urple (is per cent, and the carbolized plaster 31 per cent of 

 the frnit. which would lia\'e been wormy in the absence of an\^ treat- 

 ment."" 'i"he autlioi- would not recommend the carbolized plaster, even 

 if better results wei-e obtained from its use, because '* it does not kill 

 the insect in any of its stages, but simply drives the moths to seek 

 the fruit of neighboring trees on which to deposit their eggs."" 



The fact that " excei)t in northern latitudes, where the insect is 

 single brooded."" the ordinary method of estimating the results of 

 such experiments gives too snnill percentages of fruit saved, is dwelt 

 u|)on at couhiderable length. The author holds that "in order to 

 estimate the actual protection obtained, the counts for the two broods 

 nnist be kept separate."" In this wav alon(> will proper account be 

 taken of '* the great number of eggs that will be laid upon the 

 sprayed trees liy moths flying in from the checks, i.s well as the 

 >niallei- number of egus which will be laid on the ch'^cks, because of 

 the great nuiulx'r of larva- of the first brood destroyed on the treated 

 trees in their ^"icinity."" Tables are given in which approximate 

 data for tlie two !)roods in the expei-iment reported, are recorded 

 separately.
