F ikk-Escmm:.—The fire-escape shown in the accom-panying illustration, is made up of a series of inter-meshing links, which are individually hooked intoeyes set into the side of the building. The advantageof this construction lies in its cheapness and simplic-ity, and the readiness with which the links may be ap-plied or removed. The links are formed of metal rodsbent to a U-shape, or similar to the links of a lad-der, or square link chain; but the free ends of eachlink are bent back to form hooks for engagement withthe eye. In setting up a ladder the bottom link isfirst applied; then the ends of the next link are passedthrough the first link and hooked on to their respectiveeyes, and so on, each link serving to hold in place theupper end of the one immediately below it.
