blight, the disease would extend down young branches as much as from 
twelve to eighteen inches, and in one case as much as two feet. Seventy- 
seven inoculations were made into the trunks of two-year-old trees. All 
but seven of them failed to develop the disease. In the successful infec- 
tions, only small superficial cankers were produced. In these cankers 
a new cambium would readily form, and the entire wound would heal over 
perfectly in a short time. 
“The origin of this species, or type, is still a matter of dispute. It 
has been confused with Pyrus pashia of northern India, from which species 
it is very distinct. Pyrus variolosa produces medium sized, pear-shaped 
fruits, which have a persistent calyx. It is possible that this is not a dis- 
tinct species, but a hybrid. If this should prove to be the case, it probably 
will not come true to type from seeds. This matter will be determined 
by a study of the seedlings of this type. If this does not come true to type 
from seeds, the seedlings may be of little value for root stocks. If this 
should prove to be the case, it will, nevertheless, be of value as a stock for 
top-working, when propagated by budding or grafting on some other root 
system.”
