peach trees in their section, the methods employed for controlling it 

 and the success of such methods. A large number of replies were 

 received, owing to the fad that this was an especially favorable sea- 

 son for the development of the curl, and it is expected that the tabu- 

 lation of these replies will show interesting facts in regard to the 

 general practice of peach-growers in controlling this disease, and also 

 as to the results that may be expected in the years when the disease 

 is especially severe. It is planned to tabulate the results, and to 

 present them in the form of a short bulletin some time this winter 

 or early spring. 



Firc-hlight in nurseries. — During the past year, some observations 

 have been made and field work done in co-operation with a nursery 

 company in the control of fire blight in the nursery stock. The ap- 

 parent increase in the amount of blight on apples throughout the 

 State seems to have extended to the nursery, and the losses in many 

 nurseries this year were very heavy. However, in the nurseries in 

 which the co-operative experiments were being conducted there was 

 relatively little loss this year, although the disease appeared as usual 

 in manv of the blocks. The recommendations for the control of the 

 disease in nursery stock were to locate and cut out all old trees or 

 parts of trees harboring the disease in cankers and blight cankers, 

 and the careful and systematic cutting out of the blight in the young 

 trees throughout the season. The work was performed by the 

 nurserymen under the general direction of this department. The 

 work seems to have been done eflfectively, for while other nurseries 

 not far awa}^ suffered from the disease, there was relatively little 

 loss in the one under the control of this department. 



Tlic plant-disease survey zvork was continued in co-operation with 

 the United States Department of Agriculture. The increase in the 

 correspondence has been very marked. Many circular letters regard- 

 ing plant diseases were sent to growers all over the State, and the 

 replies, together with the reports of the regular plant-disease re- 

 porters in dififerent sections, give evidence of the general interest 

 among growers in plant-disease matters. It is expected to continue 

 this work and to enlarge it next year, as it is thought that in this 

 way the department can get at many important facts regarding the 

 general practices and the amount of loss from dififerent diseases. 



Extension Work. 

 The extension work dining the past year has been a continuatidii 

 of that begun last year. Much of the correspondence of the depart-
