appears to be true of beaTv dressings of stable manure. 

 Tbe less improved varieties of tomatoes, like many of 

 tbe old angular sorts, and tbe cberrj and plum varieties, 

 are almost exempt from attack." 



The Winter Blight 



Professor Bailev bas described, under tbe name of 

 Winter Bligbt, a malady of greenbouse tomatoes tbat 

 sometimes proves disastrous to attempts to force tbis 

 fruit. It bas tbe general appearance of a bacterial 

 bligbt, altbougb no definite proof bas yet been made 

 tbat it is caused by bacteria. Wben first attacked tbe 

 leaves become dwarfed and somewhat faded, witb indis- 

 tinct yellowish spots on the surface. ''The spots grow 

 larger, until they often become an eighth of an inch 

 across, or even more, and they are finally more or less 

 translucent. This injury to tbe foliage causes tbe j^lants 

 to dwindle, and tbe stems become small and bard. 

 Fruit production is lessened, or if tbe disease apjoears 

 before tbe flowers are formed, no fruit whatever mav 

 set. In two or three instances in wbich young plants 

 were attacked, tbe disease killed tbe plant outrigbt ; but 

 a diseased plant ordinarily lives throughout tbe winter, 

 a constant disappointment to its owner, but always 

 inspiring the vain hope tbat greater age or better care 

 may overcome tbe difficulty." This bligbt has not been 

 observed to attack the fruit. As stated above, it appears 

 to be due to bacteria — a species of micrococcus — but is 

 different from tbe tomato bligbt of tbe Southern States. 

 Various remedies have been tried witbout success, and 

 the best 2:)reventive measures are those of the immediate 

 destruction of all blighted plants, and tbe use of new 

 soil in tbe greenhouse each fall. 



The Bacterial Tomato Blight 



Tomatoes in tbe Southern States are commonlv 

 affected by a bligbt similar to, if not identical witb, the
