On Liming Land. 303 
mild lime is in its effects on land somewhat similar to 
that of dung, as it gives out its strength to the first crop} 
but in one or two crops more it is all gone; whereas 
though the hot lime sometimes, instead of helping, 
rather injures the first crop, its good effects continue for 
many years. He showed me a clover field, one part of 
which had been manured. with Mr. Barnitt’s hot lime, 
and the other with Mr. Baker’s mild lime. I observed 
that wherever a heap of the hot lime had. lain, not a 
blade of vegetation of any kind had appeared, though 
Mr. Mill’s told me that every particle of it was shoveled 
off as clean as possible ; but on that part of the field 
where the mild lime was put, no such effects were pro- 
duced. He told me further, that the grain was best on 
that part where the mild lime was put, but the clover 
is greatly superior on the other part, (it was all plaister- 
ed alike) and Ihave no doubt that the succeeding crops _ 
will evince a decided preference, in favour of the hot | 
lime. I’expect to procure specimens of both the above 
limes, for the purpose of having them analyzed.*

* Having procured specimens of the above varieties of © 
limestone, and. by the polite attention of Mr. James Cutbush, 
have been favoured with a chemical analysis of each of them, 
(for the results of which see the letter annexed) we are en- 
abled to judge of the striking similarity, between these and 
the specimens which were analyzed in England by Mr. Ten-
