there is not time for the heat
waves to meet under the blossoming
trees, before the air currents carry
the heat into the upper stata.
Years OF experience have proved
that forty square inches of fire area
IN one place is as large a fire as
should ever be used. The forty
square inch opening has come to be
known as the STANDARD" opening.
Experience has also shown that for
each degree of rise In temperature,
400 square inches of fire area per
acre, are necessary ON the average.
This will vary. OF course; high winds
will make necessary greater heat,
while ON very still nights, often half
this amount will accomplish the
same purpose.
At this average it will require
four thousand inches of fire area.
per acre to raise the temperature
ten degrees.
With the staadard opening for
each heater, lit will require one hum
dred heaters to accomplish this re-
suit. 1t will take an opening of
eighty square inches of fire area.
per heater, If only fifty heaters are
used. This is my reason for COM
demning large fires.
Large receptacles ARE more expen-
sive AND the grower very seldom is
willing to purchase al large heater, If
it is going to cost him double as
much, and therefore he compromises
hy using half enough of the large
heaters We orchard heater manufac-
turers are to blame for this, however,
for We assure our customers that half
as many large heaters are just as eff
fhcient, in spite of the enormous num-
Der of scientific facts that prove we
are wrong. The growers take our
word for it Rnd they are the ones
who suffer.
My objections to large fires are
principally the fact that large fires
create a strong draft which carries
the heat far up into the air, and
causes the cold drafts to rush i'm
from the sides to take its place. And
that large fires do not heLt evenly.
In one place the heat will be great
enough to scorch the trees, while
half way between the fires, Jack
Frost will probably be getting i'm
mis- work. This is always the case,
unless twice as much heat is being
produced as is necessary.
Large receptacles are nice and I
recommend them, for the grower who
Is willing to use them as reser-
yoir to save refiIling So often This
is the only excuse for the existence
OF large heater, and it should be
borne I'm mind that just as soon as
6 large receptacle is used for the
purpose OF creating more heat, a
greater quantity of fuel will have to
be consumed, and the heater will hav
to be ,eflled just as often as If it
were small heater.
80 strongly do l feel upon this
subject that would rather see the
growers use a common lard pail,
which is patented by no Ollie, using
$50 Of them to the acre, than have
them use only SO of our No. 3 or
some other reservoir heater, for rae
ly will a season. pass without the
need for greater heat than can be
obtained from fifty heatres with the
standard opening; ut would be bet
ter to use three times las many little
heaters, We'll distributed, lighting
them as they are required, than to
increase the heat by opening the SO
reservoir heaters to the imtremedi-
ate or reservoir opening and the cost
Of equipment will be less. Some peO-
pie say that the heaters will be in
che way, and THAT the fewer used to
the acre the better. This is not so.
Large fires have to be placed in the
open, away from the trees which
places them JIM the way of hauling,
spraying. blowing, etc., while small
fires can be placed i'm the tree rows
and out of the way CT both cmfw
and out f the way OF any orchard
work l have usde both in bcmfwy
work. l have used both hn my or
chards and know how they work.
Orchard heating DIS no longer an
experiment but has become one of
the most important branches Of Or
chari work There ae thousands to
testify as to its great protection; We
all know of the great need for the
same in ell sections; therefore, these
subjects are not SO important, but
the ways and means of obtaining the
best protection with the least cost,
is of vital Importance, aud merits a
thorough discussion and the closest
Investigation.
