blows Of" through the safety valve,
since this will cause a difference in
pressure between the steam on the
outside of the jar in the Gamer and
that inside of the jar, resulting in
part of the contents being forced
out, or the rubber being pushed out
of place. The temperature must be
high enough to sterilize the contents,
which, for meats, is not less than Is
pounds of steam pressure. At the end
Of the period of sterilization do not
let the steam escape fro mthe can
ner, but turn out the fire or lift the
Gamer from the fire and let it cool
until the steam gauge shows that
there is no steam pressure in the
Gamer. Then open the petcock, I'M
cover, lift out the jars carefully,
avoiding any draft, seal immediate
ly by fastening the lid or pressing
down the wire springs and allow to
cool in a place free from drafts.
Can Bermuda Grass BE Destroyed
J. B. c., Lyerly, Ga, writes:
Can Bermuda grass be killed? If
so, what is the best method?
How do soy beans compare with
eowpeas as a land improver?
Bermuda grass can be killed out
proceed as follows: PloW the land
! Immediately very shallow. This will
give the freezes ensuing between
now and early spring an opportunity
to act on the exposed roots. Many
of the sets will thus be destroyed.
Of course, there will be a large num-
Der left in the soil and these will
start to grow off vigorously just as
soon as spring opens up. The best
| thing to do under the circumstances
1 low GO
soon as it is warm enough seed the
! land to velvet beans or cowpeas.
These crops may be seeded alone or
in combination with some companion
crop that will make their cultiva-
tion more desirable from the stand
They are two of the most effective
smother crops we can use, and Ber-
muda grass, as you doubtless know,
cannot stand continuous shading for
any length of time.
| 1t is, of course, late in the sea-
son now to sow oats but if you could
break some Of this land Immediately,
you might SOW oats and as soon as
they are harvested follow with one
of the legumes indicated above. 1t
may be necessary to continue the
use of smother crops on the land
for two years in succession. Clean
cultivation or a hoed crop the sec
ond year will generally enable you
to effectively control and destroy
Bermuda grass.
There is little to chose in our opin-
ion between the soy bean and the
cowpea as a soil builder. Possibly
cowpeas may gather and store lit
tie more nitrogen than soy beans. A
good deal depends on the relative
growth which these crops happen tc
make There is a wide variability
in the varieties of beans and peas
adapted for planting in Georgia. We
think where one grows the Iron
kthe Whippoorwill, the Clay or the
Brabham cowpea and the Mammoth
Yellow soy bean, there will not be
much difference in the size of the
crop harvested or the amount OF
nitrogen which will be gathered in
the crop or the soil in a given sea-
son. In our experience th~ soy bean
will outyield the cowpe& in so far
as grain production is concerned, and
where one wishes to eTChasiZe this
matter, we would favor the planting
of SOW beans. We have found the
soy bean a very valuable crop tc
feed to hogs, especially if combined
with corn or shorts. These animals
relish the beans and will harvest
them readily. There upright, bushy
tyne of growth offers them some adj
vantages over cowpeas for use IN
hay production. On the other hand
the stems are coarser and not so
readily eaten as in the case of cow
