three years’ growth, on which a wide open expanded wound appears, 
encircling about one half of the circumference and situated on the 
apex of the three-years-old portion of the branch. This severe 
wound, it will be observed, has not hindered apparently healthy 
although stunted growth on the two-years-old portion of the branch 
beyond it.

branch from the Warberry Hill tree. Although the branch, 
which had about four years’ growth, was entirely encircled with

the wound, and the bark remarkably swollen and distorted, yet 
the prolongation of the branch was showing strong signs of 
vitality, and was apparently in a healthy condition both as 
regards the wood and the bark. The diseased bark, which as I have 
observed is much swollen, has assumed a corky nature where 
solid, and has expanded very irregularly. Here, it will be 
observed, the disease is gradually entering the wood (fig. 3), 
and has gone through the wood of the last -year’s growth. 
Fig. 4 and the section, fig. 5, show states of the disease 
occurring on branches of sixteen to eighteen years’ growth. 
Fig. 4 is a patch of the disease of rather long standing, 
widely gaping, and exhibiting the rugose bark well filling up
