Other examples might be readily quoted in support of the 
fact that the practical or market-value of feeding-stuffs is de- 
pendent in a large measure upon the use which the farmer has 
found by experience to make of them ; but sufficient evidence, I 
trust, has been given in this paper showing that the real market- 
value of purchased food is affected by purely practical con- 
siderations, and that the proximate composition of articles of 
food, although giving useful hints to the intelligent stock- 
feeder, does not afford a full insight into their relative merits, 
nor supply data for estimating with precision their market or 
money-value.

VII. — Notes on Inoculation of Grass Land, as practised at 
Kimholton. By Morgan Evans. 
To those who read the Report on " Laying down Grass Land to 
Permanent Pasture," in the last half-yearly volume of the Journal, 
the following communication from his Grace the Duke of Man- 
chester will sufficiently explain the object of this short paper : — 
Kimbolton Csistle, Huntingdonshire, 
November, 1875. 
Sir, — In the Report on " Laying down Land to Permanent 
Pasture," in No. XXII. of the Royal Agricultural Society's 
Journal, at page 449, Mr. Morgan Evans quotes Mr. P. Purves 
as follows : — " I should decidedly say that, as a general rule, no 
occupving tenant can do so (lay down old arable fields for per- 
manent pasture) advantageously, as it will take a lifetime to 
make good old pasture out of old arable land, and at such an 
expense as no tenant, even upon an ordinary lea^e, would 
encounter." Mr. Evans thinks that this may possibly be an ex- 
treme opinion. 
The subject in question seems to me so important, that I trust 
you will allow me to state that I believe Mr. Purves's opinion 
to be entirely warranted in reference to sowing grass on the stiff 
clays of this neighbourhood. I think it likely that he had in 
his mind an experiment that was made in my park shortly 
before and after 1855, when four fields were laid down in grass 
with great care. They are not yet good pasture,
