wise to keep a close watch upon the artificial nest, in case of a hawk jumping off when it can run but cannot fly. It might stray for ever so far, and hide in bushes, or be devoured by a cat or fox. We suppose now that the eyesses are at hack. Even yet their outer wing feathers will not be fully down; and the sails, even of those which will ultimately be the longest winged, appear rounded at the ends, like those of a sparrow-hawk. But they will very soon learn to fly quite well, with a rather gliding movement, the tips of the feathers bending upwards as they strike the air. They will not go far from the spot where they are turned out. What sort of place should this be that is chosen for the hack ground? That depends upon the facilities which the trainer enjoys for selecting a country. None perhaps is better than a large park, with fir-trees in it, or an open moor with a few stone walls. If the falconer is nervous about turning out a whole nestful at once, he may tether one of the most backward at a block in the middle of the hack field, with a "tiring" to amuse her, and place some garnished lures on the ground near to her, to which the liberated hawks may come when they like. There should also be spare blocks put out in the field, upon which the hack hawks may jump if they like after feeding. Of course, if the weather is very wet, the commencement of hack should be deferred till it is more settled, and the hawks brailed and let loose in an empty room or loft. If they have been "manned" pretty well before they are turned out, and will allow themselves to be taken up when feeding on the lure, they may be taken in under shelter the first night or two. But if it is fairly warm and fine they will be better left out. They will generally at or soon after sunset go up into pretty tall trees to roost. If they stay too long on a block or a gate or post, it is as well to drive or take them off, and see that they are perched up somewhere aloft, out of harm's way. By the bye, hawks, as a rule, should be turned loose in the early part of the day, after a light feed, so that they may be sure to get hungry again by the middle of the day. Jubilee, the best hack hawk I ever had, when he was let loose at 7 a.m., having never before flown two yards, spread his wings, and at the first start flew softly but steadily away across a small river, and, rising easily, took perch 300 yards off on the top branches of an elm 70 feet high. He afterwards flitted about from one high tree to another within a range of 500 yards, and only at midday came down to his sister, who was eating her luncheon at a block in the hack field. He spent that night in a tall elm, not far off, and did not go more than half a mile from the hack field until he was taken up nearly a fortnight later.
