68 The Canadian Horticulturist. 



which he reviewed the lessons which we, as horticulturists, have had so clearly 

 placed before us by the various exhibits of fruit at the World's Fair. He 

 showed that in almost every instance, fruits which were natives of any section of 

 country, were those best adapted to that district, and that, as a rule, exotics 

 which had been bred under different conditions of climate and soil, were not a 

 success. This he appHed to the experiments which are being conducted in the 

 introduction of Russian fruits. 



In our opinion, there is a great deal of truth in the views expressed by Mr. 

 Watrous. While we may find an occasional variety among the Russians which 

 will succeed in Canada, and be of value to us, there is no doubt at all that the 

 varieties, which are to be most successful in our northern section, will result 

 from experimental work in raising seedlings of native varieties and hybridizing 

 them with kinds already known. 



Bordeaux Mixture for the Mildew of the Grape. — On our fruit 

 farm at Maplehurst we have a vineyard of about twelve hundred vines, and 

 during the last five years the vineyard has been more or less affected with 

 powdery mildew ; the Salem has been affected more than any other variety ; 

 Brighton has been considerably injured; Wilder and Concord also to some 

 extent. Each year we have applied flower of sulphur, scattering it freely through 

 the vineyard upon the leaves and upon the ground. The result has been fairly 

 satisfactory, but has not given entire immunity. During the past season 

 Bordeaux mixture has been carefully applied to the whole vineyard, first before 

 the leaves opened and afterwards two application at intervals of about a fortnight 

 each. The result has been completely successful, scarcely a trace of the 

 powdery mildew, or of brown rot, being observable. The latter in other seasons 

 was very destructive to the Salem. At the same time, a young vineyard left 

 unsprayed, showed indications of the presence of these diseases.
