The figures embrace the amount re-
moved by both grain and straw. In
wheat. oats and rye a greater amount
of phosphoric acid than of potash is re-
moved by the grain, whereas the straw
takes much larger amount of potash.
This indicates phosphoric acid for full
heads and potash foHastrength and de-
velopment of straw. Of course, it
must be remembered that nitrogen will
be necessary also. In the case of corn
| phosphoric acid is the dominant of
both the plant and the grain.

Has crimson clover been found val

At heexperiment station in Louisiana
experiments are being conducted with
crimson clover, Gnfolium incarnation)
as winter renovation and spring hay
| crop and we will soon have the benefits
of the experiment. At our own station
| it has not succeeded well except on very
rich ground. The seed of this clover
should be sown in September or October.
| PEAR LEAF BLIGHT.
Will you please give me the remedy
Blakely, Ga.
Pear leaf blight is one of the most
difficult diseases that the horticulturalist
has had to contend with and at the ex-
| pertinent stations many remedies have
4 L. 49, H. L., 80 49, L
have been suggested, one of which may
be classed as remedial and the other as
preventive. AS remedy while it
disfgures the tree the knife has been
used with best success. This consists
| in removing the effected parts by cut
! ting. The cutting should be we'll back
in the sound portion of the tree, other
wise the blight will again attack the
| limb. AS a preventive either of the
two great solutions for fungus growth
or insects are used i. g, Bordeans mix
| ture and ammoniated solution of copper.
| For preparing these mixtures we refer
| you to past reports.
HOG RAISING, ETC.
| Is hog raising on the increase or de-
crease in counties that have the stock
i law? Is there any remedy to keep these

They seem to be eating the skin of the
cattle in holes. w. B. Med,

Hog raising, so far as the information
at the command of the department ex-
tends, is generally ON the increase
| throughout the state.
In regard to your questions as to the
horn fly we reproduce article on this
subject from the June report of 1892:
THE HORN FLY.
In some portions of southern Georgia
last year cattle were very much annoy
ed and their condition reduced by the
ravages of a small fly about one-half
the size of the house fly, which it re-
sembles in general appearance. In Vir-
ginia this fly is known as the horn fly,
or buffalo gnat. The latter name has
become current under the misapprehen-
sion that the fly is identical with the
southern buffalo gnat of the Mississippi
valley. However, the injury done by
the horn fly is not to be compared TO
that of the southern buffalo gnat, and
indeed there may be no fear of any
immediate danger to the life of stock.
For the benefit of those sections of the
state infestc with these pests, we give
several sele .tions from the report of the
etomologist of the department of agri-
culture of the United States.
LIFE HISTORY.
The eggs are deposited during day
light, chiefly between 8 a. IN. and p.
m, and more particularly during the
warm morning hours. They are laid
singly, and usually upon their sides
upon the surface of wet dung the mo-
ment the latter is dropped. So far as
known they are laid upon no other sub
stance, and never when old. The Larvae
upon Matching descend, remaining.
however, near the surface. When they
are grown they are about two-ffths O.
an inch in length, and Of normal color
and form. The time elapsing from the
egg to the adult is from 10 to II days,
averaging. say, two weeks, and there
