plants, though it could not overcome the previous ill effects of 

 the drought on some crops. An early frost, coming about 

 September 13, cut the season rather short, and caused consider- 

 able injury to corn and late tobacco. 



Diseases Prevalent in 1911. On account of the comparatively 

 dry spring and very dry early summer, fungous diseases were 

 not prominent, especially those that get their start in the spring. 

 Among the more prominent may be mentioned the following: 

 Sun Scorch, Sooty Blotch and* Speck Rots (due chiefly to Black 

 Rot and Fruit Speck) of apple ; Scab of beets, prominent in the 

 vicinity of Norfolk ; Leaf Spot of celery ; Black Knot of cherry 

 and plum; Bark Disease of chestnuts, especially bad, apparently 

 because of drought injury to the trees; Anthracnose of cucumber 

 and muskmelon, and also Leaf Mold of the latter host; Leaf 

 Scorch of hemlock, etc. ; Bacterial Blight of pear ; Tip Burn 

 of potatoes ; Mildew of rose ; Calico and Pole Burn of tobacco. 



On the other hand, certain diseases were less conspicuous than 

 usual, and in some cases not seen at all. Among these were: 

 Rust and Scab of apple, less prominent than usual because of 

 the comparatively dry spring ; Rust of asparagus, not uncommon 

 at the end of the season, but late in starting, and so not especially 

 injurious; Anthracnose of string beans, apparently quite incon- 

 spicuous ; Mildew of Lima beans, not found at all ; Brown Rot, 

 causing little injury to cherry and plum, and not so much as 

 usual to peaches; Leaf Curl of peach, comparatively inconspic- 

 uous ; Scab of pear, very much less than usual, even on suscep- 

 tible varieties ; Late Blight of potatoes, entirely absent except in 

 the northwestern part of the State, where it caused a little rot 

 of the tubers ; Rust of quince, less prominent than usual. 



Weather Conditions in 1912. The year 1912 presented weather 

 conditions rather different from those of the preceding year. 

 In the first place, the winter was unusually severe, some of the 

 coldest weather for years being recorded during January. As 

 this followed much warm weather in December, it killed a good 

 many fruit buds, particularly peaches, so that this crop was quite 

 light, especially inland. This cold also produced some injury to 

 the wood of peach trees, but not nearly so much as in some of 

 the preceding severe winters. 



The spring was very wet in April and May, and as considerable 

 rain had soaked into the ground during the winter, this largely
