APPENDIX. No. XIII.

From Mr. Govurn, Jate Steward to the DUKE or PoRT~ LAND, on making fonds in dry pastures.

The most approved method of making ponds or arti- ficial pools in Derbyshire.—After removing the earth and forming a proper bason, take a quantity of lime,(ashes of lime will answer the same purpose) and spread the same over the whole surface, about five inches thick; upon this bed of lime lay a coat of well tempered clay, eight inches thick: this must be beat down extremely well with wooden hammers, to prevent the clay from cracking. Upon the top of the clay lay a second coat of lime, of the same thickness as the first: the whole is then paved or pitched with small stones to prevent the cattle from inju~ ring the materials of the pond; the clay will naturally hold up the water, and the lime prevents the worm from striking upwards or penetrating downwards to injure the clay.
