Note 1 — Pear Blight.—No. 2.

Note.—The shock as to vital force is demonstrated by the fact that when young trees are not trimmed at all their girth increases more rapidly, and they bear fruit sooner. Moreover, when old trees are severely pruned (though not half the proportion of wood is removed) they fail to bear during the next year. I find that a hemp cord about the size of the stem of a tobacco pipe (one-fourth inch diameter) will soon become imbedded in the bark if firmly tied around a limb, and perhaps this size is more efficient than a thicker cord.
