whether we will or no. Then I am pleased to report three vig- 

 orous diseases which are invading the raspberry plantations of 

 western New York, but all of which can be kept in check by 

 digging out the bushes or by cutting them off and burning the 

 brush. This may seem to be heroic treatment, but one who begins 

 it with the very first symptom will generally suffer very little loss ; 

 and the practice in keeping his eyes open will make him a better 

 berry-grower all around. 



Yellow^ red rust or orange rust, is the disease best known to 

 growers. This disease is generally known by the very thick orange-

red covering of spores on the under surfaces of the leaves in 

 early summer. These leaves curl when badly affected (Fig. 130), 

 and make the diseased plant conspicuous at a considerable distance. 

 This stage of the disease is often seen on wild bushes of raspberries, 

 blackberries and dewberries. The sharp berry-grower, however, 

 does not need to wait until this discoloration appears for the young 

 canes on affected plants are slender, cylindrical, and usually wholly 

 destitute of prickles. The botanist is able to detect the disease 

 upon the first unfolding leaves. This malady permeates the entire 

 plant, and is therefore, incurable when once established. The 

 orange-discolored leaves fall in early summer, and the plant may 

 appear to recover later in the season, but the following year the 

 plant will be found to be weaker and probably wholly worthless, 

 and the orange coating will return. It is now known that another 

 disorder which makes spots on the under surface of raspberry and 

 blackberry leaves (and known as Puccinia PecMmia^), is really a

 the statement is made in the third edition of my Horticulturist' a Bule-Book (page 

 70), that this fungus is a fonii of the anthracnose.
