Tables are given sliowing the results of the various treatments. 

 Lime-sulphur at one gal. concentrated to 33 of water does but little 

 harm before blossoming : after blossoming, it possibly reduces the 

 quantity of apples somewhat, but does not cause the russeting charac- 

 teristic of Bordeaux mixture. The greatest damage is done two weeks 

 after blossoming, while at this time Bordeaux mixture is comparatively 

 harmless, in so far as russeting of the fruit or dropping is concerned. 



Taking the previous years' results into consideration and reckoning 

 the cost of materials, the best and most economical combination of 

 materials would seem to be : — before the blossoms, lime-sulphur 

 with arsenate of lime in a weaker solution than that used in any of the 

 experiments, viz. : — 1 to 75 ; immediately after the blossoms, about 

 1 gal. commercial concentrate of lime-sulphur to 50 gals, water, with a 

 reduced quantity of arsenate of lime ; two weeks after the blossoms, 

 a very weak Bordeaux mixture. 



An orchard sprayed almost exactly according to this plan gave very 

 successful results.

Serious damage due to Syntomaspis drwparum, Boh. (apple-seed 

 Chalcid) is fortunately only local at present in Nova Scotia. Crab- 

 apples, as well as several varieties of cultivated apples, are attacked and 

 the same or a related species attacks the fruit of the hawthorn {Cratae- 

 gus). It is not likely however to become a serious pest, since its damage 

 to the fruit is very slight and apple-seeds have no commercial value. 

 The only possible control seems to be the collection and destruction 

 of all wind-falls in infested districts in the autumn [see also this 

 Review, Ser. A, v, p. 122].
