be increased by this practice and the
assimilation of that applied to the soil
artificially more completely insured.
These are the principal matters to be
kept in mind in fighting the boil weevil.
That they are fairly effective remedies
is shown by the fact that many farmers
continue to grow cotton successfully
years after weevil infestation has. first
occurred. 1t is true that hundreds of
others in the same territory fail but
this is due to their failure to institute
and follow the methods of practice sug-
gested above.

ner indicated, you should apply them
to your corn at once. They should be
scattered down the middle of the drill
row and narrowed into the soil. Phos-
phoric acid and. potash are rather slow

most of these elements would be assiIn-

these materials on as early as posi-
BILE 1t would be best to apply them
before planting the corn and mix thor
oughly with the soil. The use of side
applications of heterogeneous materials on
corn is a good practice. Nitrogen is one
o. the elements chiefly necessary in pro-
ducing a good yield of corn. We would,
therefore, advise "a very liberal use of
it and would make application at rela-
lively early date, certainly by the time
the corn was knee high. OF course you
could use any carrier of nitrogen that
is obtainable. Nitrate .of soda is one
of the hest materials to use, but under
the circumstances you naturally cannot
apply it Blood is a very fine form of

plant. Apply at the rate of 100 pounds
per acre a good grade of blood. AS you
know, it carries about II per cent avail
able nitrogen. If you cannot secure
blood on the basis indicated, we would
suggest tie use of 200 pounds of the
secure The blood or cotton seed meal
should be scattered down the middle of
the drill row just before you expect to
cultivate the corn and covered lightly
into the soil. This will be the best
method of applying side applications of
nitrogen to corn at this season Of the
year.
Damage Effected by the Red spider
]. Y. r., Robinson. Ga, writes: My cot
ton is dying of some thing which looks like
rust, but by examining it with a magnify
ing glass ! found under the leaves very
red spotted and then dry up and fall off.
Please tell me if there is anything that
viii stop this trouble.
I judge from what you say that your
cotton has been attacked by what is
known as the red spider. The females
vary in color from red to yellow or
green to brown. This is a mite and
very small, therefore, it is rather diff
cult to see except when observed under
a magnifying glass. 1t causes severe
losses to cotton growers in some sec
tons of the south in a favorable year,
for its development may cause a damage
to the extent of several thousand dol
lars in state as large as Georgia.
The best methods of control in fight
all weeds and trash in the winter that
border the cotton fields. Beds of violets
where the mite occurs should be spray
ed Cotton, where the pest has proved
destructive in previous years should be
! widely spaced and pulverization of the
surface of the ground very thoroughly
I is also recommended, as it renders mi
4 grafton difficult. The following spray
! compounds may be used: l pound arsen-
/ ate of soda in % gallons of water. This
/ is a very effective spray to be used
on the cotton, but it is a deadly poison
/ and must, therefore, be handled with
| care and means provided to prevent
| animals having access to the poisoned
| plants. One ounce of cyanide of pota-
! SUM in ? gallons of water is also an
| excellent remedy This is also a deadly
poison and must. therefore, be handled
| with skill and care.
Whatever spray is employed there
| should be two applications with an in
terval of seven to eight days between
them. 1t is important that all parts
OF the plant be covered, but particular
| ly the affected part, which, as a rule, is
| the under side of the leaves. Soap
solutions may also be used in fighting
| the red spider. These are, of course
much safer and more simple to prepare
| but probably not so effective as the
| use of the materials suggested.
