 blight. 



No difference noted... . 



No difference noted

 more blight than 

 poorer land.

Remarks. 



Sometimes prevented by cutting off 

 affected portion. 



Good results obtained by washing with 

 1 peck stone lime, 10 lbs. sulphur, 2 

 oz. crude carbolic acid, mixed with 

 water and applied as a paint. 



Injury most common on south side of 

 tree. 



No difference noticed. 



Ground cultivated ; no difference 

 noticed. 



Finds regular cultivation and manur- 

 ing productive of good results. Occa- 

 sional cultivation with heavy manur- 

 ing injurious. 



Has had good results from splitting 

 the bark, which hardens after the 

 tree is attacked. 



Gives an instance of trees in rich 

 ^ound being attacked, while those 

 in sod escaped. 



Cutting off affected ]X)rtions appar- 

 ently checked spread of disease. 



Does not believe in growing pears in sod 

 Affected branches should be removed. 



Recommends cutting off diseased por- 

 tions. 



Recommends c*ittingoff diseased bran- 

 ches and mulching trees with coal 

 ashes ; uses no barnyard manure. 



Reports good results from the use of 

 Bordeaux mixture. 



Believes in seeding down the pear 

 orchard after three or four years 

 and manuring annually. 



Recommends cutting off affected 

 branches. 



Generally worst on low, damp, culti- 

 vated ground. 

 See letter. 

 Branches cut off and destroyed. 



Clean cultivation given and advo- 

 cated. 



Believes in growing on dry, airy situa- 

 tions and fertilizing with wood ashes. 



Thinks neglected trees are most liable.
