A strip of plating,5 feet wide and | inch thick, is worked upon the beams andcarlings and runs throughout the compartment. This completeswhat may be termed the framing of the mast-step, and the onlyother part requiring notice is the manner in which the teak chocksare fitted and bolted that form the bed to which the step-plate issecured. These chocks are 12 inches thick in the neighbourh
