It seems now very plain, that if 23 pints of leys, as above, produce of neat profit 2s. 1½d.; that 256 pints, the whole produce of the quarter hundred of ashes, will be 23s. 2¼d. or at the rate of L. 4, 12s, 9d. per cwt.; and as more of the weak leys were still to run, the profit, of course, must have been something more.
