On the Valuation of Unexhausted Manures. 
in the ' Agricultural Gazette,' objected, first, that my plan of com- 
pensation would give the outgoing tenant nothing more than the 
consuming value of his straw, and afterwards, that it would give 
him no more than he could already obtain. Neither allegation 
was true. The real question at issue is, however, not whether 
on the plan proposed the outgoing tenant would receive less or 
more than under any other arrangement, but whether he would 
receive as much as he was entitled to for his outlay. In answer, 
I put as an example a case which, with some modifications, I 
repeat here. 
Suppose a farm of 400 acres cultivated on the four-course 
system ; that the tenant enters upon it in a low condition ; that 
after years of clean farming, and the liberal use of purchased 
food and manures, he leaves it in high condition ; and that, 
accordingly, it yielded at the time of entry, and the time of giving 
up, respectively, the following average amounts of produce. 
Average Produce per Acre. 
On Entry. 
On Leaving. 
G tons. 
12 tons. 
28 bushels. 
42 bushels. 
1 ton. 
2 tons. 
24 bushels. 
36 bushels. 
It will be unnecessary to complicate the subject by taking into 
account the oats consumed by the horses, as the amount of 
manure produced from them would not be materially different at 
the two periods. Also for the sake of simplicity, the same pro- 
portion of straw to corn may be assumed on entry and on leaving, 
though it would doubtless be higher under the improved con- 
dition. Let it be assumed, then, that in each case half the 
roots are consumed in the yards ; that previous to entry no 
purchased food had been employed ; that during the later years 
of the occupancy 25 tons of linseed-cake wore used annually ; 
that for every bushel of wheat (of GO lbs.) there was an average of j 
100 lbs. of straw, and for every bushel of barley (of 52 lbs.) an 
average of 62^ lbs. of straw. 
Adopting these data, the following are the amounts of. straw,) 
and the estimated amounts of dung, entered upon, and left.i 
respectively; and the difTerence between tlie value of these on 
entry and on leaving, together with the proportion of the manure-
