Coming now to specific maladies, the commonest and not the least dangerous of the complaints to which trained hawks are subject is the "croaks" or "kecks," an affection of the throat akin to what is called bronchitis in the human patient. Its existence is betrayed by a wheezing or hoarseness, noticeable as the hawk breathes. In slight cases the sound is scarcely audible, and only very occasionally; but when the attack is a bad one, the breath is impeded, and the invalid appears to be suffering from a sort of asthma. These severe attacks sometimes come on suddenly in bad weather, and generally prove fatal; but the milder attacks, if attended to in time, may often be mastered and vanish permanently. The cause is usually the same as that which would in men induce a cold in the head or throat,--a chill caused by sudden changes of temperature, excessive cold, or, most frequently of all, excessive damp. The remedy is to put the sufferer in a warm and dry place, and to give the most palatable and nourishing food in moderate quantities at reasonably short intervals, with a peppercorn or mustard-seed now and then. Freshly-killed birds are the best diet; but if sheep's heart or butcher's meat is given, it should be first warmed a little. The hawk should not be left out of doors after midday, or in a place exposed to the wind. Strangely enough, gers, whose habitat is in more northern latitudes than any other hawks, are the most susceptible of all to this malady; and special care should be taken, therefore, that they are not allowed to be in damp or draughty places. Cramp is a terrible disorder, also caused by damp or cold. It is specially apt to attack the short-winged hawks, and is, I believe, always fatal. Eyess sparrow-hawks taken too early from the nest are pretty sure to develop it when there is no maternal wing to cover them at night. Possibly by keeping them in an artificial nest in a warm place the mischief might be averted; but the slightest chill seems to bring it on, and when once it takes hold of the feet and legs it appears to paralyse and permanently disable them. Beginning with a mere stiffness in the joints, it increases in malignity until the sufferer loses the use of one or more limbs, and then often paralyses the muscles of the back. When the very first symptoms of anything like stiffness appear in a goshawk or sparrow-hawk, no matter of what age, she should be taken at once into quite a warm place, and the affected limb fomented with hot water and embrocations. Unless these remedies speedily give relief the most humane thing to do is to put the hawk out of her misery at once. In this matter not only is prevention better than cure, it is the only means known of combating the dreaded disease.
