In the years 1825 and 1826, the foliage of our hedges in the spring months was unusually mangled by the caterpillars of different moths; but in 1827 these creatures had increased so much, that the entire leaves of the sloe, and the white thorn, were consumed by them; the hedges, when consisting of these shrubs alone, presented for miles the appearance of winter sprays, covered with a cottony web. The other hedge plants were little injured. The larvæ of several species of small creatures were concerned in this annihilation of verdure; but the little ermine moths (phalæna evonymella, and ph. padella) were the chief performers in this denuding process. In July the perfected moths swarmed about the scene of their birth in vast numbers; yet such was the retrieving power of nature, that by the middle of August only a small portion of the injury occasioned by these creatures was to be observed, the summer shoot bursting out, and covering the sprays with the verdure of spring. The chief singularity in all this was the appearance of the sloe bush, all the foliage being consumed by insects, or crisped away by severe winds, leaving the sprays profusely covered with the small young fruit, perfectly uninjured, and proceeding in its growth; so that, by the time the foliage was renewed in August, it had obtained its usual size. This was the case too with the crab, and some of the orchard fruits, presenting the unusual sight of fruit growing alone on the boughs without leaves; so that in fact the offices of inspiration, transpiration, and all their consequences, usually accomplished by the leaves of plants, must have been suspended, or performed by other organs, as no deficiency of vegetative powers was apparent. But insects alone were not the cause of all the denudation and unsightly appearance which our orchards and other trees so remarkably presented this year; for the destruction of the foliage was accomplished in part by some malignant influences, not well understood. Like the Egyptian king, we are accustomed to attribute all our evils of this nature to the “blasting of the _east_ wind;” yet we find all aspects and places obnoxious to it; one situation may be exempted for a period of many years from such visitations, when others suffer; on a sudden, a partial or a local stream of hot, cold, salt, or what we denominate a pestilential wind, sweeps along, and it is destroyed.
