 (pp. 5-7). — An account of the life history of this fungus and of 

 remedies to prevent its spread. The article is based on the assump-

Experiment orchard. W. H. Bishop, B. S. (pp. 47-51). — This tells 

 of the land chosen for the orchard, condition of the orchard, and 

 objects kept in view in selecting and arranging the trees, and gives a 

 full list of the varieties of fruits planted. 



The lines of work for which the orchard has been planned are as 

 follows : 



(1) A general variety test for the information of the fruit-growers 

 of the State. 



(2) A comparison of stock from Xorthern and Southern nurseries. 



(3) A part of the orchard has been prepared for experiments with 

 different fertilizers '• to ascertain their effects upon trees and fruit." 



(4) A collection of dwarf apple-trees (dwarfed by grafting on the 

 stock of the Paradise apjole) has been planted to obtain ''results which 

 will aid in the selection of varieties for further trial " and to compare 

 the dwarfed and standard forms of the same varieties.
