It must not be supposed, however, that the passage peregrine, or any other of the big long-winged hawks, any more than the eyesses, take kindly to rook-flying. Some have so little fancy for this unattractive quarry, that they can never by any skill be induced to fly them with any zest. Generally it is necessary to use either a make-hawk or bagged quarry for entering the beginners. The way in which such quarry are used has been sufficiently explained in the last chapter. But, as everyone does not know how to catch a rook, a few hints borrowed from the sister art of bird-catching may not be out of place. The commonest way of entrapping a rook is to send a boy up to the top of a tree in a well-frequented rookery with the end of a string, with which he can make a noose or nooses, and set them on the old nests to which the birds resort before roosting for the night. At the moment when the noisy crowd come back to the rookery and settle on their accustomed perches, a simultaneous pull at several lines connected with properly-laid nooses will generally secure a victim or more. Another plan by which a rook is made to look even more foolish is to go round with a plough in a field where rooks come to pick up the worms which it turns up. The rook-catcher must be provided with a number of paper hoods made like large extinguishers, and these he will place upside down in the furrow with a tempting bait--grain, worm, or meat--in their inside. The rest of the inside of each cap is well smeared with bird-lime or some other very sticky matter; and the rook, in picking at the food, may be hoped sometimes to hood himself. Then while in his astonishment he struggles to get rid of this blinding fool's cap, he may be picked up and carried off into captivity.
