GENERAL REMARKS 
Fig 
beneath it, there is often an accumulation of sap in the swollen vessels in a quantity 
sufficient to flow out in a rapid stream for a moment after it is wounded. This blighted 
part bears large and healthy fruit, as represented in the cut.

layer of new bark formed beneath the old bark; c, living 
interior the wood of last year, through which the life of the 
stem beyond the constricted portion is preserved.

dead or blighted portion, in the centre of which stands 
a dead stem.

projecting point extending up to the centre of the dead 
stem ; cc, dead bark extending around the dead stem ; e e ,

This dead portion is a patch about an inch and a half in 
diameter, measured along the stem. It does not, however, 
embrace the whole of it or extend entirely around it; and 
it is not unusual for the blight to affect an area in which 
there is a small branch in its centre, or nearly so. 
Close observation upon the state of the weather, the 
character of the winds, etc., seems to be highly important. 
We ought to remark that the disease appeared to have 
ceased its ravages for three or four weeks preceding the first 
of August. Our heaviest rain for the season occurred on 
the 30tli of July. The heat of the three days after this 
heavy rain, had been rather oppressive ; and now, the fourth day, the leaves of the branches, 
which are remarkably vigorous, begin to curl and lose their bright green, as if another 
attack had commenced. A few days will determine the fact. We may remark, too, that 
Fig. 
the beautiful and vigorous pines of Mount Hope, the 
residence of Mr. Prentice, exhibit the same pheno¬ 
mena as the fruit trees. The terminal branches in 
these pines, is the seat of the disease. It does not 
seem to extend to the large branches. One fact in 
regard to Mr. Prentice’s garden and orchard, ought 
not to be forgotten, viz: that he uses much stimulat¬ 
ing, azotized manure, from his establishments. It is not stated, however, as proving that 
high living, in the case of vegetables, predisposes to the blight; and yet, it appears that 
some of the worst cases of the potato disease have happened when they have been highly 
manured. The effect of rich manures, especially those abounding in organic matter,
