It is then that the rooks forget their usual stateliness and their shy and lofty habits.  Instead of keeping up in the high regions of the air, swinging on the breezy tree-tops, and looking down with sovereign contempt upon the humble crawlers upon earth, they are fain to throw off for a time the dignity of the gentleman, to come down to the ground, and put on the pains-taking and industrious character of a labourer.  They now lose their natural shyness, become fearless and familiar, and may be seen plying about in all directions, with an air of great assiduity, in search of building materials.  Every now and then your path will be crossed by one of these busy old gentlemen, worrying about with awkward gait, as if troubled with the gout, or with corns on his toes, casting about many a prying look, turning down first one eye, then the other, in earnest consideration, upon every straw he meets with; until, espying some mighty twig, large enough to make a rafter for his air-castle, he will seize upon it with avidity, and hurry away with it to the tree-top; fearing, apparently, lest you should dispute with him the invaluable prize.

Like other castle-builders, these airy architects seem rather fanciful in the materials with which they build, and to like those most which come from a distance.  Thus, though there are abundance of dry twigs on the surrounding trees, yet they never think of making use of them, but go foraging in distant lands, and come sailing home, one by one, from the ends of the earth, each bearing in his bill some precious piece of timber.

Nor must I avoid mentioning what, I grieve to say, rather derogates from the grave and honourable character of these ancient gentlefolk; that, during the architectural season, they are subject to great dissensions among themselves; that they make no scruple to defraud and plunder each other; and that sometimes the rookery is a scene of hideous brawl and commotion, in consequence of some delinquency of the kind.  One of the partners generally remains on the nest, to guard it from depredation, and I have seen severe contests, when some sly neighbour has endeavoured to filch away a tempting rafter that has captivated his eye.  As I am not willing to admit any suspicion hastily, that should throw a stigma on the general character of so worshipful a people, I am inclined to think that these larcenies are very much discountenanced by the higher classes, and even rigorously punished by those in authority; for I have now and then seen a whole gang of rooks fall upon the nest of some individual, pull it all to pieces, carry off the spoils, and even buffet the luckless proprietor.  I have concluded this to be some signal punishment inflicted upon him, by the officers of the police, for some pilfering misdemeanour; or, perhaps, that it was a crew of bailiffs carrying an execution into his house.
