3. The member, called a regulator, is an oblong piece ofbeech-wood, 61 inches in length, 31 inches broad, about ■§■of an inch thick, in which there are four holes placed for therope to pass through; one of these is open at the side; thereis also a notch at the top of this piece of wood, and an ob-long hole about f of an inch from the bottom.

4. Another appendage is called an upper belt, which is astout leathern strap, about 4 feet 3 inches long, 1J inchbroad, with a buckle to it.

5. The lower belt is a strap also, of the same sort as theother; this is for the purpose of additional security, in casethe tongue of the buckle should break by accident.

6. Another member is called an union strap, which is, weunderstand, so named, from its connecting the regulator tothe other parts of the machine. This is leather, of about11 foot long, and 1J inch broad; like the others it has abuckle to it. It is stained black, which colour serves todistinguish it from the other leathern straps.

The method of putting all those parts of the machinetogether, is first to pass one end of the rope through theholes in the regulator, then through the two lower rings inthe suspension iron; the upper belt is then to be passedthrough a doubling of the union strap ; after which the ropeis then to be tied to that belt, and the knot secured by astring from slipping, (which string is to pass through twosmall holes in the leather,) and at about a foot below therope, is to be tied to the lower belt in like manner; next,the union strap is to be put through the oblong hole in theregulator, and buckled, by which the upper belt and theregulator will be connected; the other end of the rope maybe kept wound round a wooden roller, to prevent it fromgetting entangled.

Persons who purchase these machines should have astrong iron hook, with a spring catch, to fasten to somesecure part of the window-frame or elsewhere; on this hookthe suspension iron is to be hung by the upper ring, whenany one wishes to descend from a window. The next ope-ration is to step into the lower belt with both feet, and todraw it up sufficiently high, so as to form a kind of swing tosit in: the part of the strap which is through the hole, is tobe laid hold of by the left-hand, and the buckle, with theright-hand, is to be slipped to its proper place, according tothe size of the person; the tongue is then to be put into oneof the holes, as in buckling common straps. After this isdone, the upper belt is to be somewhat loosely buckled
