The first business of the meeting was the
reading by Secretary Wiley, referee on fer
tlliZers, of the results of the various an
alyses made during the year of the several
fcruli5ing agents in order to determine the
amount of available organic nitrogen con-
tanned in each. The experiments were con-
Quoted at the Agricultural Department here
and at experimental stations in Virginia.
Maryland, Maine, Vermont, North and
South Carolina, Kentucky, New Jersey,
New York, Rhode Island and Connecticut.
The methods used included the keldahl,
the permanganate of potash solution and
pepsin solution. and the fertilizers used in
the experiments embraced dried blood. cot
ton seed meal. tankage, dried fish, meat
scraps, castor pomace, steamed leather,
bone meal and hoof meal.
Chemists Tables.
The tables accompanying the reports of
the various chemists who conducted the
experiments were read, and Prof. Wiley
recommended that further experiments be
conducted during the coming year with the
permanganate method, and advised certain
formulas to be used in connection with
them. At the conclusion of the referee s
reading general discussion was INDUCED
in, and remarks were made by G. H. Jones,
H. J. Wheeler. J. A. Myers and others.
Mr.. c. H. Jones. referee on potash for
the present year, next submitted his report.
Experiments were made with wood ashes
and cotton hull ashes.
The methods used were the Lindo-Glad-
ding and the optional. and the results
reached were almost the same. The an
alysts were A. W. ogden, New Haven; c.
c. Mcdonnell, John Thompson and F. S.
Shriver. Clemson College. South Carolina /;
b. o. White and c. H. Jones, Burlington,
VT; G.. E. Patrick Washington, d. c.;
Walker Bowman. Louisville, Ky, and F. b.
Neitch College Park, Md.
The results showed the cotton hull ashes
contained a very large percentage more of
potash than wood ashes.
Makes RecOmme II da ton.
In conclusion, Referee Jones recommend
ed that the Undertaking method should
be used in all future analyses of wood
ashes and cotton hull ashes for the deter
mination of potash.
In the discussion which followed Mr. B. 3.
Ross presented some interesting facts
which had been developed in using ashes
tos for the purpose of fltering. He had
found the asbestos lost weight when certain
agents We're used in the solutions filtered
through it. especially ammonium chlorate
even after having been boiled with hydro
chloric acid
This statement caused an interesting in
terchange of views, participated in by Mr..
Jones, Mr.. H. J. Wheeler and others, Mr..
Wheeler suggested that further expert
ments be made.
The hour of noon having been reached,
Secretary Wiley made several announce
ments. He extended on behalf of the Co.'S
mos Club to all members cordial invita-
ton to make the club house their own and
enjoy all privileges it affords. Recess was
then taken until 10
The Afternoon Session.
The afternoon session, which did not be-
gin until nearly = o'clock was devoted to
the consideration of the reports from the
committees which had been created last
year to follow up the investigations into
phosphoric acid soils and ash. and foods
and feed stuffs. The reports were techri-
cal in character and evinced very great
care the part of those who had con-
Quoted the laboratory experiments in con-
neCtion with the subjects
a very inpor tant subject to be considered
tomorrow morning will be the report of the
committee on food adulteration. At the az
ternocn session tomorrow the election of
