ture land, it must do mischief. My advice therefore is, that the 
proprietor of a farm, when he receives a parcel of rock-salt from 
Northwich, should make a point of having the whole of it ground, 
or reduced to a powder nearly as fine as common table salt, and 
passed through a sieve of the requisite fineness, before he allows 
any of it to be laid upon the ground. Rock-salt is not a hard 
substance: it may easily be crushed and divided as much as is 
necessary for any of these purposes. 
As to the quantity of salt which it will be advisable to use for 
the respective crops, and upon the different kinds of land, this 
will be best learnt by a perusal of the several testimonials and 
other documents which will be found in the Appendix. But the 
best way of all others for asvertaining this point would be for 
every agriculturist to depend upon the results of his own experi- 
ments. To this end, I would advise him to institute a set of ex- 
periments upon every distinct species of grain which he is in the 
practice of cultivating, as well as upon his pasture land *, and to 
keep a register of every minute circumstance attending each of 
these trials. 
A large kitchen-garden, wherever there is one attached to a 
farm-house, would in some cases be the most appropriate spot 
for such experiments; as this would be more under the imme- 
diate eye of the proprietor, and the experiments being upon a 
small scale, would be attended with little or no expense. The 
circumstance of an agriculturist being now empowered to divide 
the salt which he shall obtain by permit, among as many of the 
neighbouring farmers as he may think fit, is extremely favourable 
to such circumscribed experiments, and will be very gratifying 
to those who may wish to satisfy themselves of the value of com- 
mon salt, and yet would not like to incur the risk of buying a 
large parcel solely for their own use. And as the late act allows 
the use of salt in agriculture, as well as for feeding all kinds of 
cattle, this affords a large scope for its consumption. 
From the trials which have already been made in feeding tile 
live stock upon a farm, it appears that the following quantities 
may at all times be administered with perfect safety. 
To neat cattle four ounces of salt per day, mixed up with 
steamed chaff or other moistened food; one half to be given in 
the morning, and the other half in the latter part of the day. 
To horses four ounces per day, as aforesaid. 
* The right honourable Sir John Sinclair, baronet, lately published a 
series of sixteen distinct experiments, which he is desirous of having tried 
by farmers, as best’ calculated to ascertain the advantages of using salt m 
agriculture ; and he distributed the paper gratis. This valuable sheet, 
which may be obtained at the Board of Agriculture, is well deserving the 
attention of all practical men.
