Note 4 — Chapter VIII

"On sixteen square rod of ground in my lower pasture, I put 140 Bushels of what we call Marle viz on 4 of these, No. Wt. corner were placed 50 bushels--on 4 others So. Wt. corner 30 bushels--on 4 others So. Et. corner 40 bushels--and on the remaining 4-20 bushels. This Marle was spread on the rods in these proportions--to try first whether what we have denominated to be Marie possesses any virtue as manure--and secondly--if it does, the quantity proper for an acre." His ultimate conclusion was that marl was of little benefit to land such as he owned at Mount Vernon.
