Hawks are sometimes troubled with a weakness in the outer joint of the wing, causing the outer part of it, where the primaries are, to droop. The affection is more or less pronounced in different cases, sometimes being so severe that the wing seems to hang down powerless, as if merely hooked on loosely at the joint, and at other times merely to be a little out of place and to be carried slightly lower than the other. Occasionally the weakness is so great that the hawk cannot fly, while at other times, after perhaps wobbling a little when thrown off, the hawk, once fairly on the wing, seems to fly almost or quite as well as if there was nothing the matter. Generally a hawk which is so affected keeps hitching up the bad wing, as it were, into its proper place, only to find it droop again in a few minutes into its old position. The old writers, who were well acquainted with the symptoms, say that the injury is one which must have arisen from a blow received by the hawk; but I have known it come on suddenly at a time when the sufferer could hardly have come by such an accident without its being observed. The following is a prescription given by Turbervile for curing the malady:--"Master Cassian (a Greek falconer of Rhodes) sayeth that yee must take Sage, Myntes, and Pelamountaine, and boyle them all togyther in a new earthen pot full of good wyne, and when they bee well sodden, take the potte and set it uppon hotte imbers as close stopped as maye bee. Then make a rounde hole of the bygnesse of an Apple in the clothe that your potte is stopped withal for the steam to issue out at. Which done, take your Hawke upon your fiste and holde out hir hurte wing handsomely a great whyle over the hole, that it may take the fume whiche steameth up out of the potte. Afterwarde lette hir be well dryed by keeping hir warme by the fire, for if she should catche sodaine cold upon it, it would becomme woorse than it was before. Use her thus twyce a daye for three or foure dayes togyther, and shee shall bee recovered."
