6/22 The foremost part of such a plough is cut to a point, and into a groove made for the purpose a section of tough oak is inserted, to serve as a share. It is held in place by the tapering of the groove, and some wedges or plugs. The share has naturally to be renewed quite frequently, but it serves its purpose where the ground is not stony. Later on, in Cusarare, Nararachic and other places, I found ploughshares of stone applied in the same manner as were the wooden ones. On crossing the ridge to Piedras Azules, sixty-odd miles south of Temosachic, a decided change of climate and vegetation was noticeable. |
