about ten shillings, therefore four tons of merely wetted straw 
is only worth half-a-crown a ton as dung. On the other hand, 
if a ton of straw be used as litter for twenty weeks for a fatten- 
ing bullock, receiving about 17 lbs. per day of cake — say of 
cotton and linseed cake — besides clover, hay, and roots, the 
original ton of straw has most costly additions made to it. Is 
the manure worth the extra cost and additions ? Most people 
would answer no. As few farmers have either boxes or covered 
yards to preserve any kind of manure, what part of the original 
value of the manure in the food would remain after repeated 
washings ? Just in proportion to the number and thoroughness 
of the washings, we may suppose ; and these are frequent 
enough iu all ordinary seasons. Again, when dung does con- 
tain a good percentage of nitrogen, it seldom shows such favour- 
able results in the crops as artificial manures, containing much 
less in quantity, but in a more readily available form. 
The cost of oil-cake dung is apparently very great. The 
notion that the land will get richer is true ; but will the ordinary 
farmer who makes it get richer or poorer ? Artificial manures
