/ One pound of linseed oil will
replace five pounds of hay or two
to three pounds of grain. But,
cows must get at least a third
of their vitamin A in the supple
ment.
Weaned calves wintered on the
range will gain more on two
pounds of 20 percent protein pei
lets if either vitamin A or phos-
phorus is added.
Concrete Work
If it looks like cold weather
will arrive before you ear get
that concrete job done, you can
still do it providing you take
certain precautions and keep in
mind that low temperatures slow
down the setting of concrete.
First, be sure the ground is
not frozen when you prepare the
excavation and subgrade. Unless
the weather is very cold, a COW
ering of straw or other material
will keep the ground in the ex-
cavation from ferezing. Also be
sure to remove any ice or snow
in the forms before the con-
crete is placed.
When air temperatures are
generally about 40 and As de-
grees with only short periods
below this range, a covering of
tarpaulins may be sufficient to
maintain proper temperatures for
curing newly-laid cement.
However, when the tempera-
ture gets near or below freezing
you'll have to heat the mixing
water or the sand and gravel
in the mixture. And at extremely
low temperatures, both the mix
ing water and the sand and grav-
ell must be heated. And, of course,
you must cover the fresh con-
crete or provide a heated en-
closure.
An important point to remem-
with a temperature higher than
165 to ITS degrees. Water that
is hotter than this may cause a
FLASH set" when it comes in con-
tact with Portland cement. Also
the temperature of sand and
gravel should not exceed 100 de-
grees when they are placed in
the mixer, Never heat the ma
terials to such a high tempera-
ture that the fresh concrete will
be above 80 degrees when it is
poured or its strength will be
lowered.
Then there are two other points
to keep in mind on cold weather
concrete work. Never heat the
Portland cement and do not per-
NIT ice, snow or frozen Jumps of
sand and gravel to go into the
Strawberry Culture
Have the leaves on your straw
berry plants started to turn a
reddish color? If so it's time to
put on a straw mulch to pro-
,ect the plants over the winter.
Some folks depend on a snow
cover to protect their strawberry
However, this is not too
dependable since the snow may
lot arrive until after sharp
freezes have occurred. On a win
,er thaw may remove the snow
and expose the plants.
Experiments have demonstrated
hat a mulch applied too early
be detrimental too. In fact,
he plants need a few frosty
lights to encourage certain chem
cal changes that make them more
esistant to below freezing tenn
creatures. The critical tempera-
ure level is Is to 20 degrees
'a~hrenheit. Temperatures below ,
his level can damage the plants. ,
In mulching, place the straw j,
yer the entire strawberry bed :,
D that it settles to a layer three :
r four inches deep. If your area :
windy it may be necessary to :
old down the mulch with chick
n wire. Straw is recommended 7
ecause it does not pack around Q
lie plants as leaves and other {
laterials are likely to do. I
When spring comes it is not
ecessary to remove all of the q
!ulch. A little left around the T.
