The different kinds of manure usually employed in this neighbourhood are sea-weed, sand, stable-dung, ashes, and fish-dung. The quantities vary so much according to the condition of the land and other circumstances that it is impossible to state with any degree of accuracy what quantity is applied to the acre. In one of the conditions of leases previously quoted, it is stipulated that 10 butt-loads of good town or fish dung, and 10 butt-loads of sea-sand (to be mixed with the necessary quantity of earth) shall be carried for every acre broken up for tillage.
