On the Valuation of Unexhamted Manures. 
The examples given in respect to both feeding-stuffs and 
jnanures, of the great and variable difference in the amount of 
compensation that would be awarded for unexhausted residue 
according to the customs of large agricultural districts on the one 
liand, and on the basis of valuation according to composition on 
the other, are, to say the least, very striking. Little doubt can 
lu' entertained, that much better evidence of their fairness and 
i^t ncral applicability than at present exists would be required 
before attempting to apply the scale of allowances adopted in 
special agricultural districts to the country at large. 
I am quite willing to grant that wide differences exist between 
the soil, climate, and other conditions of the agriculture of other 
<listricts, compared with those of my own farm. Indeed, although 
I cannot admit that the experimental results obtained at Rotham- 
sted afford no data upon which, with care and judgment, im- 
portant general conclusions applicable to other and different 
conditions may be founded, yet I have already said that, even 
supposing the basis upon which my own estimates of compensa- 
tion are arranged were adopted, the exact scale of allowances 
might require considerable modification, according to the 
characters of the soil, of the climate, of the individual seasons, 
and other circumstances. 
It will, perhaps, be said that so long as both parties interested 
agree to accept terms of compensation, which, whether fair or 
not, those subject to them may at some future time in their turn 
exact, no great harm is done. But in the event of a system of 
compulsory compensation being adopted, proof of the value of 
the unexhausted residue of feeding-stuffs and manures will be 
required of the claimant ; and I would ask — where are the scien- 
tific witnesses, having characters to lose, who would assert that 
the unexhausted residue from all purchased feeding-stuffs and 
manures may be valued on the basis of the original value or 
purchasing price of the article ? 
Section III. — Estimation of Compensation for the Unexhausted 
Residue of purchased (or saleable) Feeding-stuffs and Manures, 
Ijy the Valuation of what is above ground, and has a recognised 
and easily-ascertainable Money-value. 
I freely admit that the tenant farmer has an equitable claim 
lor compensation for the unexhausted manures he leaves in the 
soil when he quits his holding. But I think anyone who has 
carefully considered the schemes of compensation discussed in 
cither of the foregoing Sections (I. and II.) of this Paper will 
agree with me that, even with the best intention, and calling to 
our aid all the knowledge, both practical and scientific, which
