The result of the use of the diluted Bordeaux mixture was, by 

 Professor Green, a saving of three quarters, at least, of fruit which 

 would otherwise have been ruined, besides increasing the size of the 

 fruit itself, and giving it greater beauty for market purposes. In ad- 

 dition to this there resulted a brighter and healthier foliage upon the 

 tree itself, which means a great deal for the vigor of the orchard. 

 The excellent effect of spraying with this mixture is shown in the 

 results of Professor Green's experiment at the Ohio Experiment 

 Station with the Newton Pippin, a variety perhaps more subject to 

 scab than any other. Of the 100 apples from the sprayed trees, 15 

 were first class, 74 second and 11 third, while of the same number 

 of apples from unsprayed trees there were no first-class samples, only 

 40 second, and there were 60 third-class. Thus it appears that, while 

 spraying does not wholly prevent the scab, it pays well for the outlay 

 required of time and money. 



There are other ways in which the results are beneficial besides 

 those mentioned. The leaves of our trees, when affected by the 

 scab, fall prematurely, carrying with them much potash and phos- 

 phoric acid, a direct loss to the strength of the tree. Now, if the 

 leaves can be made, by spraying, to hold fast until the proper sea- 

 son for maturity of growth, these fertilizing constituents will be with- 

 drawn from the leaves into the body of the tree, and there be stored 

 up for the following year. This spraying is useful also in blight and 

 some think in plum knot. 



Tomato Rot. — This is a fungus for which no remedy has been 

 certainly found. It is very wide-spread in Ontario, and does great 

 injury to the business of truck gardeners. Some varieties, as Acme
