The Windsor Cherry. 



65§. SiE, — Is the Windsor cherry of good quality ? 



E. B. Edwards, Ptttrhoro\ 



It is counted an excellent variety. It originated at Windsor, and was 

 introduced to the public by Messrs. Ellwanger & Barry. It is thus described 

 by that firm : Fruit, large, liver-colored, resembling the Elkhorn, nevertheless 

 quite distinct, ripens three or four days after that variety ; flesh, remarkably firm 

 and of fine quality ; tree, hardy and very prolific ; a very valuable late variety. 



Plant Louse on the Spruce. 



^!^9» Sir, — I enclose some twigs of spruce, showing some insects which infest the 

 spruce trees on my lawn. They have, for the last two seasons, stripped the branches, 

 making the trees look badly, and destroying their symmetry. Can you tell me what it is, 

 and the remedy ? 



E. R. CARPENTER,f Co^^mgfttoorf. 



Reply by Prof. Fletcher, Ottawa. 

 The insect is a species of plant louse, which I am unable to recognize from 

 the specimen sent. It is, however, very similar, if not identical, to a species 

 which has done much damage at times to white pines. This we have treated 

 quite satisfactorily with the kerosene emulsion, diluting the ordinary Riley 

 formula, which has been published in the Horticulturist, with fifteen parts 

 of water to'one of the emulsion. 



Clearing a Lawn of Ants. 



660. Sir, — How can ants be got out of a lawn or terrace ? Flip. 



Several remedies for this evil have been suggested. Air slacked lime, 

 plentifully dusted over their hills and other places infested, is one ; another is, 

 four ounces of quassia chips, boiled in a gallon of water about ten minutes, and 

 four ounces of soap added to the liquid as it cools, and this well sprinkled about 

 their nests and ruus. A remedy much commended is to stick a match, phos- 

 phorus end down in the holes they make ; as a result the ants immediately 

 clear out. 



Spraying. 



661. Sir, — Does spraying injure trees ? Flip. 



That depends upon what mixture is used. Paris green, if too strong, injures 

 the trees ; while Bordeaux mixture is a great benefit, for it prevents fungi from 

 growing upon the foliage or plant.
