At the last session of our legislature a law

part of section ten is that "lhe State
chemist, who shall properly analyze the
same, shall duly report to the secretary of
the board OF agriculture, the result of said
analysis, stating the methods used by him to
determine the amounts of potash, nitrogen
Soluble reverted and iusouble phosphoric
acid, and such amounts; ard sid secretary
OF the board of agriculture shall Capse said
reports to be published giving the name Of
the chemist making the same" and aqrecably
to this | submit the following: Professor
A. H. SaOin of the University Of Vermont At
Burlington, is state chemist, a. ofici0 to
ataly2e the same, and has analyzeda5 follows
part OF said samples, but sickness IN his
IamiIy and increased work has prevented
she completion of all the samples. The
methods used ere determination of plJs-
pm )rlc acid in absence of iron and aluminium
by uranium method; in presence of iron
and aluminium by pembertOu's molyhdaic of
amonia method; potash by precipitation with
platinum chlordes, and nitrogen by combus-
ton with soda lmc. The latter does not
give nitrogen present as ntratcs, Int is the
common methods. That the farmer may
understand their relative valut. figure their
worth as | believe it to I've a comparative
standard, by placing a supposed value to
ammonia to twenty.sjX cents: nitrogen
twenty-tour cents; soluble and reverted
phosphorlc acid at twelve and one-haIf cents ;
lnsolu0le pnosphoric acid at six cents and
potash at five cents per pound Some figure
soluble phOsphoric acid at twelve and one
half cents and reverted at eight cents, but as
| believe that the reverted is as vaublc as
the soluble, see M reason to reduce the
price for it, yet it is usual so to do.
figure thus that the farmer may see their
comparative value, as | believe from rta-
sonable standpoint; and yet, 1t does not
show that the benefit is limited to that price,
or that it will benefit you at all. This must
be found out by experiment give in the
following tables the percentage o. each in
gredeut supposed to lie valuable, as called
for in the law. First 0s found by the
average of three separate analyses of our
State chemist, and cpud as guaranteed by
the manufacturer. 1t will he seen that |
figure the worth also from the prices before
mentioned, and place the same under the
percentages Thus the farmer at glance
can see the comparative value
