Stock Mixtures. 



733. Sir, —In your March number I notice the first practical directions for making 

 Bordeaux mixture in large quantities. Will the dissolved copper sulphate and the milk of 

 lime keep any length of time without deterioration ? 



J. H. Bexn, Niagara. 



We see no reason why the solutions should not keep any length of time. 

 Of course it would be necessary to add fresh water occasionally, to make up for 

 evaporation. 



734. Sir, — Do you know of any apple trees that would be likeh" to stand this 

 climate ? 



John Parkinson, Portage la Prairie. 



Reply by J. Craig, of Ottawa. 



Our experiments at Brandon and Indian Head have shown us that 

 very few varieties of the named kinds of apples can be grown successfully at 

 any point west of the Red River. Among those which have succeeded best are 

 the following : — 



Crabs. — Whitney No. 20, Red and Yellow Siberian, and Martha. 



Apples. — Silken Leaf and Duchess have succeeded best of the named 

 varieties and have done fairly well in some localities, when planted on soil not 

 too rich. In situations like this the wood ripens better and is less likely to be 

 injured by the cold of winter than if planted on the usual heavy prairie soil. 



Nitrate of Soda. 



735. Sir, — In using nitrate of soda for a special dressing, would it be advisable to 

 mix it with land plaster, or would it be better to apply it by itself ? 



W. Millar, Oshaica. 



Fertilizers for Orchard. 



736. Sir, — What is the best fertilizer for a mixed orchard of apples, pears and 

 plums, that has been planted fifteen or twenty years ? The gi'ound has been in hoed crops 

 since planting. 



W*. H. C, Netccastle, Ont. 



Apricots not Blooming. 



737. Sir, — My Russian apricot has bloomed now for three years and borne no fruit. 

 Can you explain ? 



H. KiJPPEKT, Stayner. 



We have had similar experience with the Russian apricots and have come 

 to the conclusion they are of little value for us in Canada. The trees blossom 

 too early in the spring and are often caught by early frosts; besides, while young, 

 the tree seems inclined to drop its blossoms and set no fruit.
