 In the above analysis the sulphuric acid is combined with the lime
to form sulphate of lime (gypsum) The remainder of the lime is com-
bined with the phosphoric acid to form phosphate of lime.
 The soda is combined with the chlorine to form sodium chloride
(common salt).
 INDUCTIONS.
 The careful reader will note a very wide difference between these
soils.
 Those who have considered lime lands as unfit for tobacco will be
surprised to find so large a percentage of lime in Cuba land as well as
in the tobacco. After so widespread a condemnation of such fertilizers
as kainit, which contains a large percentage of salt, he will be impress-
ed by these analyses that our soil very generally will be benefitted by
the proper use of it. The station has used kainit and sulrphate of pot-
ash on tobacco during four years with marked benefit. We have used
as much as from 300 to 500 lbs. of kainit to the acre in compost.
 The station soil, unusually poor, was selected because of its sterility to
test the value of different manures, and while for causes above stated
the experiment was a failure in this respect, and also as to quantity, for
the same reasons, still, by reason of these manures, it produced the very
best tobacco, so far as texture and quality were concerned. It will be
further observed to what an extent iron enters into the composition of
the ulant, thus indicating, that as our soils are largely deficient in lime,
iron and salt, the latter, 'from which clorine is obtained, that fertil-
izers, such as common lime, copperas, which is sulphate of iron,
should be used, and that such salts as kainit and the sulphate of potash,
which supplies the needed potash, will furnish also, so far as kainit is
concerned a good source from which the common salt can be supplied.
These analyses are given in the hope that the observant and intelli-
gent farmer will use them to much benefit in the production of his crop.
 In this connection it may be as well to state that

 HOG PEN MANURE
has also been condemned because, it is said, it imparted the unpleasant
odor of the skunk to the segar. The past season a hog pen, used as
such for over two years, was planted, and a crop sufficiently large,
though small, was made to test the truth of this statement. No such
odor has been observed. But this fact has been demonstrated, viz.: that
