given, the leaf-blight was not present in any considerable amount dur- 

 ing the season and the efficacy of the two fungicides was not given a 

 test of any severity. The treated portions, however, remained freer 

 from disease than the untreated. 



1892. The same row which had been budded in the fall of 1891 as 

 described subsequently, was treated this season in a manner precisely 

 similar to that described for the pear stocks on page 263. Care was taken 

 that the undersides of the leaves were wet by the spray and to ac- 

 complish this the Vermorel nozzle was directed upwards. On June 24 

 the first signs of leaf blight were noticed upon the budded, untreated, 

 stocks, the unbudded stocks remaining almost entirely free throughout 

 the season. By July 10 the leaves of the untreated began to fall and 

 continued dropping until many of the stocks were left nearly leafless. 

 On October 4 a careful count was made of the number of leaves 

 which had fallen from each individual stock in the row. This was ac- 

 complished, in a comparative way, by counting the leaf scars on each 

 stock. Below is given for convenience a condensed statement of the 

 condition of the stocks with regard to height, diameter 3 inches above 

 the union, and freedom from leaf-blight. All numbers represent aver- 

 ages. Height above ground (measured September 28) is represented 

 in feet and inches, while the figures for diameter (measured October 15) 

 are in thirty seconds of an inch. Only budded stocks are here taken 

 into account.
