proves a most desperate malady. Although this 
disease has been so general, (no doubt throughout

least not as far as my observation extends. By 
some it is thought to be produced by insects. 
Tins is, however, a misconception, for I have 
paid minute attention to ascertain the fact, but 
never discovered any likely to produce that effect.

sap had become disordered, some how or other, 
so as to be obstructed in its regular courses, and 
not to be properly evaporated in line vapours, but 
to burst the delicate rind of the branches, leaves,

pletely stopped in their growth, and the fruit and 
branches will often be found to exude a portion of 
coagulated sap or matter. The fruit thus affected
