Edgefield advertiser. [volume] (Edgefield, S.C.) 1836-current, 1859-12-28

quently in his. opinion the chlorapatite or phos-
phatic rock of New Jersey, continuing ninety per
cent. or moro of phosphate of lime, must be 2.pc-
bone dust; instead of which these mineral phos-
pilates, even after being finely ground and treated
with sulphuric acid, have no value as manure.
AllSthe attacks of this gentleman we have passed
by unnoticed, not only those written over his sig
nature, but his anonymous communications pub
lshed in the Homestead We published the afi-
darit of the foreman and all the workmen at the
factory, that no change in quality had ever taken
place in the Phosphates there manufactured, and
supposed this to be m entire refutation to the as
ysis, the correctness of which had been entirely
disprored, not only by the communication Of DR..
Charles H. Enderlin, but by the analyses of DR..
Enderlin, Prof. Hosford, of Cambridge, DR.. A. A.
Hayses, of Massachusetts,, Dr. Antscll and others,
and by the opinion of Prof Shepard, formerly of
Yale College, Prof. Higgins, of Baltimore, and
others, and still further disproved, by the certf-
cntes of hundreds who had used the Phosphate for
u series Of years.
In the article referred to in your paper, Prof
johnson commences thus:
"Of oil the many fraudulent and poor manures
which have been from time to time imposed upon
our farmers during the last four years there is none
so deserving of complete exposure and shcrp re-
buke, ms that series of trashy mixtures, known as
Mapes Super -phosphates of Lime. 1t is indeed
true that worse manures have been offered for sale
in this State, but none have ever had to employ
such nm amount OF persistent humbuggcry to boil
ster them up, as has been enjoyed by these"
Now permit me to ask whether this language is
beftting the Office of Chemist who wishes to do
service to the public, or that of special pufcr
which Prof. johnson has most undeniably proved
himself to be, Of volcanic Guanos, which arc val
ueless as compared with Super -phosphates. In
his recent writings he has lost no opportunity for
putting these miscalled guanos, and his late book
is but card for the vendors of these inferior pro-
ducts in his neighborhood. He then says:
Seven or eight years ago, Mapes' Improved
Super-phosphato was almost the only manure of
the kind on sale in our northern markets then it
was of good quality" etc.
Ho afterwards says:
"And had value Calculated on present prces)
of S44 per ton; it was sold at $50 per ton"
Why should Prof. johnson calculate present
prices on an article which he states was sold at
$50 per ton seven or eight years ago In his ac-
companying analysis, after admitting the presence
of suphuric acid he denies the presence Of soluble
phosphates. This is as he is we'll aware, chcmi-
cally impossible.
My answer to the whole of this TRADE is, that
the sales Of Super phosphate in the very district
where ho resides, and where the paper is published
in which he has written most, namely, Hartford
and New Haven, have been five times as great in
the year 1859 as any former year, and the follow
ing certificates from men Of the highest standing
ugricuturists in his state and elsewhere received
within the current year, are better evidences of the
Phosphates than any analysis or opinion which
may be offered by this self-constituted servtor of
the public.
As you have given place to this unwarrantuble
attack upon me, ask in common fairness that
you will publish the above, together with the fol-
lowing abridged certificates.
I also enclose you the full certificates, that You
may see that the abridgments are fairly made.
Yours, respectfully,
