mer up to the first of August or even
later From that time until frost,
it is recommended that the water
supply be cut off so that the trees
will produce smaller and smaller
cells and will be ready to stop grow
ing when frost comes. The sowing
of a crop in the orchard will take up
moisture heavily in the month of Oc-
tober and not so heavily in Septem-
Der and Will bring this condition
about.
Wet, warm falls, following dry hot
summer often brings about bad
condition. The trees grow, but little
| in summer, when they should pc
growing, and then start a oelated
growth late in the fall. The tWlgs
green and unmatured for the winter.
Cultural methods planned to over
come these conditions are desired for
orchards with trees younger than hve
years. In bearing orchards 1t IS not
so essential.
3. Mound trees with soil late IN
the fall. Investigations have SHOWN
that the roots of trees are less re.
sistant to cold than the top. Of
course the roots are seldom killed by
cold IN Georgia, as they are protected
by soil. 1t is also known. as men
toned above, that the cells at the
base are least resistant OF the parts
of the trees above the ground, but
they are more resistant than the
roots. The farther away from the
base any part of the root system Is
located the less is its resistance 10
cold. If soil protects the roots from
being killed, it is reasonable to sup
nose that if placed in a mound around
the trunk of the tree 1t would also
protect it. AS near as it is posslD!e
TO do so it is suggested that thls
monnding be done just before 1rost'
e oh
ing the mound wide spread, about
three feet through. ,,e,

Spraying Cotton With CALCIUM
Arsenate

writes: 1 wish some informa-
ton in regard to using. calcium

titles for use next year!
Our experience with calcium ar.
senate as spray against the DOH
weeyiI is somewhat limited. We have

| practical tests of the DEMENT'S TO pc

recommending the conservative use
! of calcium arsenate in 40 per cent
| strength next year. To rely on 1T a:
| the sole means of fighting the weevf
would be a mistake. We found, how
| ever, that where five applications OF
calcium arsenate were mage at a
| acre, the yield of cotton per acre was
| increased to the value of about
! S2331. This was after allowing for
! labor at rs cents an hour, rent on
the machine, and the cost Of pickin&

all increase in yield on the poisoned

I 329 pounds of seed cotton per acre.

pounds per acre. should be put on

sons a later application might De
better. AS rule the applications
| should be made about one WeeR
apart, and we do not think over five
| applications will be necessary.
| I am frank to say that there Is
much to learn about this method yes,

Destroying Weevils in Stored
|
J. E. NJ, McRae, Ga, writes: I,
would like to know how to keep
weevils out of threshed peas;
| also what can l do to corn in the
| ear to keep weevils out?
The best way to keep weevils out
| of threshed peas and corn in the ear
is by the use of carbon bisulphide.
| The plan described below is what IS
| called the fumigation method of de-
stroying these insects. A cheap grade
of this material will give excellent
results for use against the insects
| in question. Carbon bisulphide has a
most striking. penetrating odor. The
gas generated if mixed with air is
| infiammable. 1t should thus be used
and handled only in the absence Of
Ii"h+s. The gas is also heavier than
air; hence 1t sinks down to the bot
TOM OF the bin containing the grain.
| In using this material, apply two
popnds of the liquid for every 1000
feet of cubic space. The temperature
should be around 70 degrees Fahren-
