Before the intending falconer takes any preliminary steps even towards becoming the owner of a hawk, he must make himself thoroughly familiar with the necessary appliances which he will have to use, and first of all with the hawk's furniture, or articles of attire and daily use. The "jess" (or jesse) by which the hawk's feet are secured is a strip of leather fastened round the leg, just above the foot. It is, of course, of a different length, width, and stoutness, according to the size of the wearer. For a peregrine or ger the same stuff may be used as for strong riding or driving gloves; and the softer and more pliable it can be, consistently with strength, the better. For a gerfalcon 8 in. is not too long. For a peregrine tiercel 6-1/2 in. is long enough, and for hawks of intermediate size the length may vary according to their proportions. In the case of the smaller hawks, from the female sparrow-hawk to the tiny jack-merlin, the length for ordinary purposes should be from 4-1/2 in. to 6-1/2 in. But when a jack-merlin is flying ringing larks late in the season, or indeed at any time, and it is important that he should carry the very smallest possible amount of extra luggage, his jesses may be made out of a thin kid glove, well stretched and greased, and need not be more than 3-1/2 in. long, by 1/4 in. wide, bulging out to 1/3 in. at the place where they encircle the leg, and at the other end, where they are hooked to the swivel. In all cases the jess is attached in the same way. After it has been well stretched and greased, a short slit is made near the broader end of the leather (see Fig. 1), and another a little farther down. The distance between the two slits should be about the same as the circumference of the hawk's leg--not greater, nor much less. This part of the leather between the two slits is applied to the hawk's leg, and the shorter end, being brought round the leg, is pushed through the second slit as far as it will go. Then the longer end is in its turn passed through the first slit and pulled tight. Some falconers pass the long end of the jess through both slits before pulling it tight; but the reason for this extra precaution has never been made plain. After the long end has been pulled through--or before, if preferred--a hole is punched in the leather at a short distance from the tip, and another and larger slit is made for the purpose of attaching the jess to the swivel. But if the hawk is destined, immediately after the jesses have been put on, to be turned out to hack, this end slit is not required, and should never be made, as it is possible that it might loop itself round some thorn or other peg-like object, and hang up the hawk, causing her death or some irreparable injury. Whenever a jess is released from the swivel, it is a good plan, when there is time, to twirl up the end, rolling it between the finger and thumb, so that the slit does not form a loop.
