The numerous hands employed in the one species of cultivation necessarily encourage the other, by affording a ready market for its produce. To diminish the number of those who are capable of paying for it, is surely a most unpromising expedient for encouraging the cultivation of corn. It is like the policy which would promote agriculture by discouraging manufactures.
