The tanks are also fitted, as may be seen, with some sort of outer iron framework, often termed a “ crinoline.” The two combined serve as a close and safe guide for the cable in its egress from the bottom of the tank at a more or less high * In the present article wherever an. historical example is given, it applies equally to present-day practice. leaves the a height only about a foot above that of the upper flake of cable, and the other rings in similarly suitable positions relative to the top corners of the individual cones. By this means the egress of the cable is kept in close check throughout. Having dealt with the installation of cable on board a telegraph ship, attention may now be turned to the apparatus for the various operations en- tailed , previous to dealing with the work of laying the wire. When paying out, the cable is (as may be seen in Fig. 16) drawn from the centre of the tank, through wooden or iron troughs, to a brake drum, by which a re- straining force is applied to prevent too rapid egress outboard.
