or less the disease, but still having much life in them, as they 
were forming healthy-looking young shoots and leaves well deve¬ 
loped. It is difficult to describe the character of the disease in 
this advanced state, but the drawing will show that one long, irre¬ 
gular, gaping opening runs through the whole length of the 
wound, and near the upper and lower ends there are transverse 
openings of the same nature encircling more than one half of the 
circumference. These gaping openings into the wound are mar¬ 
gined by the much diseased bark rising into various nodulous 
shapes and spreading some distance on either side. On the left 
side of the longitudinal wound the bark of the branch for some 
five inches in length, and two to three in width, has lost its 
vitality, and assumed a rufescent tint, and has a considerably-sized 
open wound on the centre of the rufescent space.
