KEPOKT OF THE BOTAOTSTS.

Besides the general correspondence work relating to the 

 diseases of plants, which is constantly increasing each year, 

 this division has continued its usual experimental work in 

 the greenhouse on various market garden and tioricultural 

 problems. 



During the past year this division has published two bulle- 

 tins, entitled, "Cucumbers under Glass," issued as Bulletin 

 Xo. 87; and "Injuries to Shade Trees from Electricity," 

 which was issued as Bulletin Xo. 91. 



From the pathologist's point of view, the past season has 

 shown some resemblance to the preceding one. Both sea- 

 sons have been })eculiar, as demonstrated by the second 

 blossoming of a large number of plants and the general up- 

 setting of their seasonal habits. There has been an absence 

 of some fungi, Avhich usually occur more or less commonly, 

 and a predominance of others which generally do not cause 

 much damage. Some indications of the })ink mold, a so- 

 called attendant of a})ple scab, which made its appearance 

 last 3'ear for the first time in this State, has shown itself 

 again, although trouble from this fungus has not been serious 

 in this State. The sooty mold of greenings, etc., has been 

 unusually abundant the past two 3^ears where spraying has 

 not been properly attended to, causing much disfiguration 

 of the fruit. Considerable damage was done to pear trees 

 by lice, which profusely secreted honey dew on the foliage 

 and stems, thereby furnishing conditions for the luxurious 

 development of a black mold on the stems and leaves, caus- 

 ing much injury to the latter.
