108. The fold is usually made with netting or light 
scantling, so arranged as to be easily taken apart. The 
form is square. The sheep are dnven in every night, and 
the fold is removed when the ground occupied by it is 
sufficiently manured. 
109. Among animal manures, we may mention flesh, 
blood, bones, horn, poudrette, etc., as all being exceed- 
ingly valuable. 
110. When a horse, or a cow, or a sheep, dies upon the 
farm, it should never be left to taint the air by its decay. 
It should be covered with mild lime, and then a heap 
of earth thrown over it, of some eight or ten times 
its own bulk. This earth becomes saturated with the 
fertilizing gases, and furnishes a load or two of manure, 
well worth the trouble of making. 
111. Bones have been known and used as a manure for 
a long time past; and on the lighter soils, to which they 
are adapted, they constitute the most valuable auxiliary 
fertilizing substance that has yet been discovered. The 
bones are reduced, in a proper machine, to the size of half 
an inch, and strewed upon the land, at the rate of twenty 
bushels to the acre. - The effect on favorable soils is great 
and lasting ; and they succeed best onfall light lands, on 
limestone soils, and on the lighter loams. On all wet 
lands, whether clays, damp loams, or moist gravels, they 
do not pay. The inference from this is, that bones are 
best suited for dry seasons and climates.*
