On the Valuation of Unexhausted Manin-cs.

icceivc compensation at the rate of l&s. for 20.v. cost of the 
manure if they were consumed on the land, and of 15s. if con- 
sumed in the yards. If a corn-crop have been grown after the 
iDots, the corn sold, and the straw left, he might receive 7s. for 
i'(\s-. cost of the manure ; if a second corn-crop, 1,9. ; or if, instead 
of a second corn-crop, grass or hay be grown and consumed, 3s. ; 
but if hay be sold, nothing should be allowed. 
If the cake be applied directly for a corn-crop, the corn sold, 
and the straw left, 7s. for 20s. cost of the manure may be allowed. 
If a second corn-crop have been taken, Is. ; but if a third, nothing 
should be allowed. If, instead of a second corn-crop, grass or 
hay be grown and consumed, after one year, 3s., or after two 
j-ears, Is. ; but if hay be sold, nothing should be awarded. 
4, Bones. 
Ordinary crushed or half-inch bones decompose less rapidly, 
and are, therefore, less rapidly active than finely-ground bones. 
In either state bones are less rapidly active than rape-cake, 
and, like rape-cake, are much less so than nitrate of soda, 
ammonia-salts, or guano. The action of bones depends, more- 
over, very much upon the characters of the soil to which they 
are applied. In heavy soils their action is very slow, and there- 
fore the more lasting ; but in light soils it is more rapid, and 
less lasting. 
In the case of soils to which experience has shown that bones 
can be applied with effect and profit for the root-crop, if so 
applied, and no crop have been grown from the manure pro- 
duced by the consumption of the roots, the allowance might be 
17s. for 20s. original value, if the roots have been consumed on 
the land, or 16s. if consumed in the yards. If a corn-crop have 
been taken after the roots, the corn sold, and the straw left, 8s. ; 
if a second corn-crop, 2s. ; if, instead of a second corn-crop, 
grass or hay be grown and consumed one year, 4s. ; or if hay 
be sold, or grass or hay consumed a second year, only Is. 
should be allowed. 
If bones be applied to suitable grass-land, which is entirely 
grazed, 18s. for 20s. original value may be allowed after the first 
year, 13s. after the second, 6s. after the third, and Is. after the 
fourth year. If the grass be made into hay and consumed on the 
farm, 16s. after one year, 10s. after two years, and os. after three 
years, may be allowed. If the hay be sold, 10s. may be allowed 
after the first year, 4s. after the second, but nothing after the third 
year.
