Nor is the rookery entirely free from other troubles and disasters. In so aristocratical and lofty-minded a community, which boasts so much ancient blood and hereditary pride, it is natural to suppose that questions of etiquette will sometimes arise and affairs of honour ensue. In fact, this is very often the case; bitter quarrels break out between individuals, which produce sad scufflings on tree-tops, and I have more than once seen a regular duel take place between two doughty heroes of the rookery. Their field of battle is generally the air; and their contest is managed in the most scientific and elegant manner; wheeling round and round each other, and towering higher and higher, to get the vantage-ground, until they sometimes disappear in the clouds before the combat is determined. They have also fierce combats now and then with an invading hawk, and will drive him off from their territories by a _posse comitatus_. They are also extremely tenacious of their domains, and will suffer no other bird to inhabit the grove or its vicinity. There was a very ancient and respectable old bachelor owl, that had long had his lodgings in a corner of the grove, but has been fairly ejected by the rooks; and has retired, disgusted with the world, to a neighbouring wood, where he leads the life of a hermit, and makes nightly complaints of his ill-treatment. The hootings of this unhappy gentleman may generally be heard in the still evenings, when the rooks are all at rest; and I have often listened to them of a moonlight night with a kind of mysterious gratification. This gray-bearded misanthrope, of course, is highly respected by the Squire; but the servants have superstitious notions about him, and it would be difficult to get the dairy-maid to venture after dark near to the wood which he inhabits. Beside the private quarrels of the rooks, there are other misfortunes to which they are liable, and which often bring distress into the most respectable families of the rookery. Having the true baronial spirit of the good old feudal times, they are apt now and then to issue forth from their castles on a foray, and to lay the plebeian fields of the neighbouring country under contribution; in the course of which chivalrous expeditions, they now and then get a shot from the rusty artillery of some refractory farmer. Occasionally, too, while they are quietly taking the air beyond the park boundaries, they have the incaution to come within the reach of the truant bowman of Slingsby's school, and receive a flight shot from some unlucky urchin's arrow. In such case, the wounded adventurer will sometimes have just strength enough to bring himself home, and, giving up the ghost at the rookery, will hang dangling "all abroad" on a bough, like a thief on a gibbet--an awful warning to his friends, and an object of great commiseration to the Squire.
