heater whose top is not adjustable
is going to give less heat the longer
it burns instead of more. The heat
ers with reservoir attachments have
an advantage over the others in that
they hold oil enough to last from two
to five operations a:~d do away with
the laborious task of reflling while
they are in action. The type of
heater that leaves the least residuum
or coke after the oil is burned is the
one that furnishes the most heat
from given amount of fuel. Those
that are made with holes at the side
near the burning surface of the oil
allow air to rush in and accomplish
this better by furnishing a more
perfect combustion. What one
should demand of a heater-other
things being equals that it be
large enough not to need refilling
during one operation; that it burn
the oil economically; that it be con-
structed in such way that the
burning surface may be readily adj
justed to suit the needs, and that
it be of such shape as to allow econ
omical storing while not in use.
The question of oil is an import
ant one. Not all grades of oil will
burn in these heaters. The ordin-
airy crude oil used for driveways is
too crude, that is, too much of the
inflammable part of it, such as kero-
sene and gasoline, has been removed.
On the other hand, one should not
buy an oil with more of the kero-
sene and gasoline in it than is nee
essary for it to burn we'll, as it costs
more. Several of the large oil firms
are putting out product they term
fuel oil' that is we'll adapted for
this purpose. 1t may be bought at
the refneries in tank car lots at
about three cents per gallon.
Facilities for handling the oil is a
matter that should not be put off
until the last minute. 1t would tie
poor business policy on the part of
the grower to depend upon storing
enough in his heaters to last thru
the season, even though they be of
the reservoir type. If it should be-
come necessary to heat three or four
consecutive nights without a supply
near at hand to draw from, the
chances are he would not be able to
get it in time. Orchard heating is
not like blowing corn, where you
get returns in proportion to the am
cunt of work done. It requires
finished job. The only safe plan to
follow is to have some sort of device
in the orchard for storing guam
tity of oil. This may be done either
in galvanized or wooden tanks or in
a cement cistern. If one is heating
ten acres or more the cistern plan is
the better. By taking advantage of
a hillside one can handle his oil
with gravity, thus avoiding the ex-
pense and labor of hand hauling,
as pumping is well nigh impossible.
The heaters may be filled with
buckets from barrels on low wagon
but tank wagon holding two to
four hundred gallons is much bet
ter. By means of a one and one-
half inch hose-the ordinary gar
den hose is too small-with a stop
cock at the free end one row can be
filled at almost a continuous drive.
The arrangement of the heaters
in the orchard will depend some
what on the type used. If the small
upright kind with the non-adjust-
able top be used, about seventy or
eighty per acre will be needed. The
ones with sliding top arrangement
so that the burning surface can be
increased to approximately one
hundred square inches if necessary,
can he placed at the rate of about
fifty per acre. Unless the trees are
headed high it is better to arrange
the heaters between the rows instead
of directly under the trees. Every
possible arrangement in the way of
placing and filling should be done
