Garden measuring tools

1777. The ground-measure. Of this there are at least three sorts used in gardening: a Gunter's chain of 100 links, or sixty-six feet; a rod of one twelfth or any equal part of the chain, marked with links on one side, and feet on the other; and a common pocket-rule. To these may be added a pocket measuring line; though it is not, from its contraction and expansion, to be much depended on. The chain is used to ascertain the contents of, or to lay out and subdivide, considerable plots; the rod for the detail of such plots, or for marking out rows, &c.; and the pocket-rule for taking smaller dimensions.
