in Agriculture.
DR. 1E. rM.h PeHdletond Professor Of
Agriculture In flfe tssf6gia State Agri-
cultasal College, 4at-the.elose ofan.elabo-
rate report Oh the results of his experi-
ments, Pae1ts the following Summary.
We reprint it here as food for thought
and us furnishings serieso points OF. de
parture for futher experiments, rather
tAahSas ep pSitehe Of agrlcultard science
Let alldoubtful statements be put to the
-testSof afather experience: 'ii ,a
!. That there is great waste of ammo
s:s when Peruvian gurno'is usedsin its
concentrated, Eats form; it, should be mixed
with super-phosphate, alkaline salts, &c.
2. Tfiae NJ Combination of salts, -leav
ii,g 6dt Soluble phosphoric acid, will pay
ontour worn soils. !''
3. That taken separately none of the
salts sold as 1eftilizers toYmake home
GIo9rIp GIoo9mrIpypepgqsy will pay. Their virtues, if
any, must berlin tchemical action upon
each other, and the substances with which
they are fomlosted, tllIl
.. That aahss trSated with .sulphulic
acid will greatly improve their fcrti i
zing qualities.
5.That two hundred pounds ola good
ammoniated superphosphoratc is about
the quantity to be used on an acre Of
cotton. SIsT II OIL ri
=. That soil abounding in vegetable
matter will pay much better per cent.
with commerc!a! fertilizers than one hav
ing but little of this substance.
q. That large amount of fertelizers
(say half aIton per acre. will not pay with
low priced 'ctaottobs''0'h cotton. 7" 7
9, That with .gopd cultivation, good fertili
zers viii pay, even at the lowest rates of
catt6n; Ibdt with bad cultivation they
will hardly pay a: any price. -.
9. That while potash is, more indispen
sable plans1ife than soda, the latter
may replace the former under certain
circumstances. ,,
10. That di-phosphatc Of lime, being
less soluble in cold water, is not SO eff
cisft' ut the ]bi9spBogphatc rs fertilizer.
II. Thatsstablc manure, either fresh or
rotted, applied with a'lhgh graded super
phosphate, makes very efficient fertili,
ger for cotton.
II. That cotton seed applied with the
itskiilllee,ll le @s g@a gresa 1if sputs in tsenl in
conjunction with good superphosphate
.nakes powerful fertilizer.rsd
1e. That lime should never be used in
conjunction withyfagzsuperphosphate, and
the application Of -superphosphates to
dalcareotis soils, Is Of doubtful utility.
IA. Fertilizers applied during the
growth Of the crop, 70 keep uP "A supply
0fnutrition to the rootlcts, will not pay
under ordinary I'll fei4rcumstqnccs. a,ss y,or
10. That dmmYoniai Yon is. the, most active
and efficient form of nitrogen, when
applied us fertilizer. and that organic

IL. That the application of soluble
1iianures infa aiqhid foam is better and
more efficient than when applied in the
dry state. itfli 1ii
-.lS. That lime will pay OH soils aboun-
ding in organic matter; or other soils its
application is doubtful utility.
10. That subsoils do an6t, germinate
seeds, or grow plants, like surface soils
20. That early planted cotton will not
protlnce as much as that planted later,
when the ground becomes warm, and the
plant is not retarded Sbut3growsoF yigor-
ously and healthily.
2i.' That subsoiling cotton lands will
pay for the extra labor on our clay soils.
