"The Author of improving wet and barren Lands says, that, by burning the Ground two Inches thick, there will be two Hundred and sixty Loads of Ashes to an Acre; and, by burning it three Inches deep, there will be four Hundred Loads to an Acre. It is true such Burning will clear the Land of Weeds and all Manner of Trumpery; but Woe be to the Farmer after the Ashes have been spent, which will be, as he says, at three Years End; for then will come on as great a Barrenness as the Ashes caused Fertility; and this for I know not how long, because the richest Part of the Ground, which is the Turf or Surface, is gone."
