This blight has been a very great pest of the orchards, in some countries of Europe, especially in parts of France, England, and the Netherlands. In 1810, so many of the cider apples of Gloucestershire were infested with it, that it was feared cider-making would have to be abandoned in that region. Sir Joseph Banks appears to have given the insect the name of “American blight,” being led to believe it had not come from France, and supposing that it had been imported from America with some apple-trees, planted in a nursery at Chelsea. An English writer on orchards says, “I have from good authority heard that it was brought to this country from France, in the reign of Louis XIV., when a colony of refugees settled at Paddington, and there it was first observed to begin its depredations on apple-trees.” This last account is far more likely to be correct, since the insect has been very common in France, while in America, we hear so little of it, that it is scarcely known to any but entomologists, and nursery men. Dr. Fitch, in the Annual Report on the State Cabinet of Natural History of New York, dated 1851, says of this aphis: “Commonly, only solitary individuals are found, and in but one instance have I met with it clustered, and covering a limb, as described by foreign writers.” It is rather remarkable that as warm seasons are said to favor its increase, our warmer summers should not have rendered it more troublesome in this country; possibly our colder winters may have a counteracting effect, although, as a general rule, insects with their larvæ and eggs, will bear great extremes of cold. NOTE GG. THE HOLLY, (_Ilex_) p. 247. We have in America two kinds of holly. One, _Ilex montana_, or Mountain Holly, is found on the Alleghanies, and the Catskills, and is seldom more than a straggling shrub, from eight to twenty feet in height. The _Ilex opaca_, or American Holly, strictly speaking, is a tree from twenty to fifty feet in height, found in most woodlands from Maine to the Southern States, where it is more common than in the northern parts of the country. It is far, however, from being a familiar tree to most Americans, whose acquaintance with the holly is apt to be more connected with their English reading, than with the reality. The foliage of the holly of this continent is less glossy, and the berries are less highly colored than those of the European tree. NOTE HH. TO WILT, page 249.
