and quince are of a similar nature to that of the pear, appearing 

 under the same conditions and are remedied in the same way. 



Leaf B'ight of the Strawberry. Of the small fruits the strawberry 

 is the only one that is seriously injured by a leaf blight. This dis- 

 ease is of a similar nature to that of the other leaf blights, attacking 

 especially plants in beds more than one year old. Some varieties, 

 and young beds under poor treatment, are sometimes attacked the 

 first year's growth and seriously injured, but when properly sup- 

 plied with an abundance of plant food and given thorough cultiva- 

 tion, little loss would occur in the annual system of growing this 

 fruit. At Amherst we have discarded the two-crop system, and 

 only take one crop of stra^vberries from the same bed. 



Mildews and Rusts. Mildews and rusts, although of a similar 

 nature and habit of growth, are given these names from the appear- 

 ance of the mass of surface fruit which appears to the naked eye. 

 Plants affected by mildews generally present a mealy or powdery 

 appearance, whence the name (mealdew) mildew, while those 

 affected by rusts have a rusty yellow or brown appearance. 



The mildew of the grape causes the most loss and is familiar to 

 almost every one who has attempted to grow the Delaware and some 

 other thin-leaved varieties. It is very abundant in warm moist 

 seasons, not only attacking the leaves, but doing serious injury to 

 the fruit. 



When planted a good distance apart, on high sandy or gravelly 

 soil, and trained upon high trellises, it is less injurious than when 

 the vines are trained low and grow on less elevated land. Good culti- 

 vation and proper plant food will, in a measure, assist in preventing 

 the disease. I have often found when the mildew first appears, that 

 stirring the soil twice a week will check it very materially. 



Blackberry Rust. On old plantations of the blackberry and black- 

 cap raspberry, a yellow or golden colored growth on the underside 

 of the leaf sometimes appears, causing the leaf to curl and die. 

 This is a parasitic growth similiar to the mildew of the grape, but 

 the fruiting parts that come out upon the surface have this golden 

 color while the fruit of the grape mildew is white. It has been my 

 experience that it develops more upon old plantations, especially if 

 neglected and that good cultivation and proper manuring will largely 

 overcome the injury. 



As plantations become old it is nrore and more difficult to keep up 

 the proper supply of plant food to insure a healthy growth, and it
