/olaw-anchors, twenty-two rope-porters, tools, 5-tined Woolston cultivator, 
4-furrow balance plough, &c. (Catalogue No., 8G5), price 2801. Owing to 
the windlass being too highly speeded for being driven by the belt from the

thrown upon the horse's back and the use of a slipper and chain is rendered 
available. When fixed for work, a couple of strong chains or shackles, A 
(Fig. 22), are fastened to two iron stakes, which are screwed into the ground 
■on the principle of the screw pile. The two winding drums, B and C (Fig.
