On the Valuation of Unexhausted Manures. 
grass or hav be grown and consumed on the farm, \s. may be 
allowed ; but if a second corn-crop be taken, or hay be cut and 
sold, no claim for compensation should be admitted. 
If guano be applied to grass-land, 16s. for 20s. estimated 
original value may be allowed after one year, 10s. after two 
years, and 2s. after three years, if the produce be only grazed : 
if it be made into hay which is consumed, 14s. after one year, 
8s. after two years, and Is. after three years ; or if a crop of hay 
be taken and sold, only 2s. should be allowed. 
D. Other Manures of more or less unknown Composition. 
Under this head may be included — special grass-manures, 
corn - manures, root-manures, or other compound artificial 
manures ; also dried blood, shoddy, Kainit, ashes, night-soil, 
soot, other town-manures, sea-weed, fish, and some other refus'e- 
matters. 
As in the case of guano, so in that of each of the above 
manures, the mere price paid for it cannot be accepted as the 
measure of its value. If any claim for compensation for the 
unexhausted residue of such manures is to be made, it is abso- 
lutely essential that the composition of the manure used should 
be known. 
It is obviously requisite that any Act by which power is given 
to an outgoing tenant to claim compensation for unexhausted 
manures should give the person subject to such claim power to 
ascertain the composition and value of the manures in respect 
to which the claim is made. In all cases, therefore, in which 
it is intended to put in such a claim, the person making it should 
be required to give notice to the landlord that he is about to 
use certain manures, from which he may have samples taken 
for analysis if he desire it. 
Professor Voolcker in England, the late Professor Anderson in 
Scotland, and Professor Cameron in Ireland, have from time'to time 
drawn attention to the numerous frauds committed upon tenant- 
farmers by the sale of spurious manures ; and if a purchaser do 
not take the trouble to protect himself from fraud when his own 
interest alone is concerned, he is little likely to do so if, bv 
afterwards claiming compensation based upon the amount of 
his outlay, he can shift a portion of the loss upon some one- 
else. 
The value of a manure of this class will depend almost ex- 
« Iusively on the quantity, and the condition, of the nitrogen and 
of the phosphates, and in the case of Kainit of the potass, which 
it contains. 
Special grass, corn, root, or other compound manures, will
