"Rooks," he subjoins, "are often accus'd of feeding on the corn just after it has been sown, and various contrivances have been made both to kill and frighten them away; but, in our estimation, the advantages deriv'd from the destruction which they make among grubs, earth-worms, and noxious insects of various kinds, will greatly overpay the injury done to the future harvest by the small quantity of corn they may destroy in searching after their favourite food." [Footnote: Mr. Bewick does not seem to have been quite aware that much of this mischief, as I have been informed by a sensible neighboring Farmer and Tenant, is done in the grub-state of the chaffer by biting through the _roots_ of grass, &c. A latent, and imperceptibly, but rapidly spreading mischief, against which the _rooks_ and birds of similar instinct are, in a manner, the sole protection. C. L.] "In general they are sagacious, active, and faithful to each other. They live in pairs; and their mutual attachment is constant. They are a clamorous race: mostly build in trees, and form a kind of society in which there appears something like a regular government. A Centinel watches for the general safety, and gives notice on the appearance of danger." Under the Title, "ROOKS," (p. 71) Mr. BEWICK repeats his observations on the useful property of this Bird. I confess myself solicitous for their safety and kind treatment. We have two which were lam'd by being blown down in a storm (a calamity which destroys great numbers almost every spring). One of them is perfectly domesticated. The other is yet more remarkable; since although enjoying his natural liberty completely, he recognizes, even in his flights at a distance from the house, his adoptive home, his human friends, and early protectors. The ROOK is certainly a very beautiful and very sensible Bird; very confiding, and very much attach'd. It will give me a pleasure, in which I doubt not that the Author of this delightful Poem will partake, if any thing here said shall avail them with the Farmer; and especially with the SUFFOLK FARMER.
