 anything especially promising-. We regard it with very much in- 

 terest as a curiosity and as a possible forerunner of something 

 good in new fruits. On this account we have raised about three 

 hundred seedlings from it. The iigure of it herewitli shows the

DISEASES AND INSECTS AFFECTING SMALL FRUITS. 



Duritig the last five j'ears the disease known as "leaf curl" has 

 seriously affected almost every variety of red raspberry on the 

 grounds of the university farm. Almost nothing is as yet known 

 of the life history of this disease, although its ravages are very 

 wide spread over this country. It is, however, well known that the 

 land once infected with it retains the infection for several years. 

 Of the older sorts of the red raspberry, the Turner seems to have 

 the power to resist the disease better than any other grown on the 

 universitj' farm. The new variety known as Royal Church also has 

 shown very desirable resistant ([ualities in this respect. This 

 disease has not affected the blackcap varieties so far as observed. 

 Anthracnose, or cane rust, of the raspberry, injures to some extent 

 almost every variety belonging to the blackcap class as well as 

 many red kinds. It has, however, been very successfully held in 

 check at the university farm by spraying the canes with Bordeaux 

 mixture. But the injury from this disease has not been nearly as 

 serious a matter as that from " leaf curl," and blackcap raspberries 

 have consequently come to be regarded as more reliable than the 

 red sorts. A detailed report of our successful treatment of this 

 disease was given last year in Bulletin No. :v.t of this station. 



There has been very little injury done to small fruits by insect 

 pests the past year. 



NURSERY. 



The station nursery is in good condition and contains a greater 

 variety of fruit, forest and ornamental trees and plants than ever be-
