The canker may be cut away with a sharp knife or chisel, 
and the wound dressed with Stockholm tar. 
That well-known Kentish rosarian, the Rev. H. B. Biron, 
has achieved successful results by making a slit in the bark 
4 to 4 inch deep, right through ite canker wound, beginning 
well above it and finishing well below. This is done in spring, 
at an early stage of the disease. The wound gapes, fresh bark 
forms, and the sap again flows strongly.
