the south, were more susceptible to leaf-blight than the imported 
French or the native-grown American stocks. The latter were 
at this date scarcely affected by the disease. ‘rom the two 
years’ experiments upon Japan stocks from Franklin Davis & 
Co.’s nurseries it seems probable that these when imported from 
the south will not show any greater immunity from leaf-blight 
than the French or American stocks. A more extended experi- 
ment, however, is needed to settle this point. The results of 
treatments with fungicides was as striking as that gained from the 
French stocks. The foliage on the budded stocks remained 
reasonably free from the disease until quite late in September 
when the stocks in the untreated portions began to drop their 
leaves badly; those treated six times with Bordeaux held their 
leaves almost intact. The Bordeaux proved in general more 
efficacious than the ammoniacal solution in the treatment of 
both budded and unbudded stocks, and six treatments were more 
effective than five. But one noteworthy exception existed in the 
first section treated five times with ammoniacal solution, which 
is possibly explainable by superiority of soil.
