Prolong these lessons, therefore, till your hawk is well "made to the lure." Each day at feeding-time make her come a longer and longer distance to it for her dinner. After a while she will be flown to it in a creance, that is, a line attached to the end of the leash, or, better still, to the swivel, from which the leash has been detached. The best way to give the lesson is to get an under-falconer or assistant to hold the hawk on his fist in an open piece of ground, and then, going a little way off, to show her the lure, on which she knows by experience that her food is fastened. In the case of eyesses which have been hacked to the lure they are of course well habituated to the business in hand. But all hawks, if properly treated, will after a time learn to look with some eagerness, at the dinner hour, for the appearance of the lure. Peregrines and all the bigger hawks will be hooded up before going out; and when the hood is taken off they will glance around in search of the trainer. As soon as they discern him swinging his lure, they should jump off and fly towards it, and, when it is thrown on the ground, alight on it. Merlins and sparrow-hawks may generally be set down on a post, and lured from it by the same person who took them out, without the need of an assistant. Or, when they know the lure sufficiently, it may be attached to the far end of the creance, and, after being swung once or twice, thrown to a short distance, and the little hawk thrown off at the same time, when she is pretty sure to go straight to it. These exercises at the lure should be continued till there is no longer any reasonable doubt that the pupil will come as soon as she has the chance; and, in order to make sure, the length of the creance may be increased from a few feet to at least a hundred yards. It will be a proud moment when first you trust your passage hawk entirely free, and, detaching the swivel from her jesses, abandon for the moment all actual control over her. On this occasion you will probably take extra precautions, making sure that no intruder will interrupt the operations, and that your hawk is undeniably sharp-set. But in order to make certain of this, do not dream of starving her; merely put off the feeding-time for an hour or so. Hawks in captivity should commonly be fed, as will be seen later on, at about 11 a.m. When you first fly your passage hawk free, wait until past noon. The small extra delay will have put an edge on her appetite. If all goes well she will not notice or suspect that anything unusual is occurring. Very likely, if a light line has been used, she may have supposed for days past that she was flying free. Possibly she has never once suspected the existence of the creance.
