Chap. XV. Miscellaneous Details. 273 iron is worked around it both above and below the plating, thusforming a short tube, which gives a bearing for the wedges. Thepartner plates a are always fitted in iron ships, and are requiredby both Lloyds and the Liverpool Rules, but in some cases woodenmast partners are fitted both above and below the plating, in orderto give a greater depth of bearing surface for the wedges. Insome ships the partner plates have been cut away in order t6allow the corner chocks of the wood partners to pass down throughin one length, but it is considered preferable not to cut the plates,and to fit the corner chocks in two parts.
