=Insects Injurious to Filberts.=--My personal observations lead me to believe that the filberts and hazels are, in this country, remarkably free from the depredations of noxious insects. Two species of nut weevils have been reported as breeding in the wild hazelnuts, viz., _Balaninus obtusus_, and _B. nasicus_, but among the many bushels of the European varieties of the filbert produced in my grounds I have never found one infested by a weevil or other insect. In Europe a nut weevil (_B. nucum_) is said to be very destructive to the wild hazel, often invading the filbert orchards, and this we can readily believe, because they are not at all uncommon in the imported nuts, but fortunately have not, as yet, become naturalized in this country. The great hazel-leaf beetle, or as more generally known, elm-leaf beetle (_Monocesta coryli_), has been known in a few instances to attack and defoliate large patches of the wild hazel bushes, but this insect seems to prefer the elm, hence is rarely found on the hazels. But should it ever invade our filbert orchards, it can be readily destroyed by dusting or spraying the trees with Paris green, London purple, or other well-known insecticides. There may be an occasional invasion of caterpillars, like the tent worms, spanworms, leaf rollers of various species, and what are called leaf miners, but as these infest almost all kinds of deciduous trees and shrubs, we cannot consider them specially injurious to the filberts and hazels. CHAPTER VII. HICKORY NUTS. Hicoria, _Rafinesque_. Name probably derived from the aboriginal or Indian word hickery, or hickory, the common name for these nuts among the tribes formerly inhabiting the Middle and Southern Atlantic States.
