Therock forming the banks of the Zambesi ishard, heavy and dense and made an ex-cellent anchor for the cables. On the sur-face of the rock between the inclined January, 1907. RAILWAY AND LOCOMOTIVE ENGINEERING shafts about 400 tons of rails wore laidto prevent any danger of the rock break-ing out, and to make assurance doublysure. On each bank the pair of halfarches was thus literally sewed to theshore as one might sew a two-hole but-ton to a stiff piece of leather by passing. METHOD OF ANCHORING THE HALF-ARCHES, the thread through, the return stitch beingmade a short distance from where theneedle first entered. The alignment or the raising or lower-ing of the top chords of the bridge wereeasily effected by tightening or looseningthe nuts on the saddle pieces in which thecable ends were made fast. The largenumber of cables which were used dis-tributed the pull, each strand doing itsown share of work like the threads bywhich the Liliputians bound the giantGulliver, and made him captive by theirunited strength. The pull on each set of cables holding ahalf span of the bridge, just before thearches were finally closed, has been esti-mated at more than one million, six hun-dred thousand pounds. To picture toourselves what such an enormous stresswould be like, if the bridge, resting onits hinged supports at the abutments, hadbeen held in position by weights inst
