be final or absolute as many factors
may enter in any night to change
conditions and which may result in
from one To four degrees difference.
Each grower must use his own
judgment when using these tables as
guide The grower should make
careful study of his trees to de-
termine the following points: Vital
ity of tree-amount of bloom
stage OF advancement of bloom, as
compared with these tables-stage of
advancement of bloom at the time of
heating operations. He should also
understand the soil conditions with
reference to moisture and tempera-
ture. This is true in orchards en-
ploying either clean cultivation or
cover crops-humidity of the at
mosphere-general location of or
chards as regards air drainage
whether his operations are reinforced
by neighborhood heating and amount
of foliage on trees.
We recommend that the grower
supply himself with sufficient equip
ment to cope with such conditions
as have been realized and sufficient
to facilitate all night work so far as
possible. He should supply plenty of
heaters. one to the tree, II the aver
age orchard setting is from . to 80
per acre. IL small heaters, double
or treble the number per acre. and
all moisture must positively be elm
mated from all kinds of fuel used.
With reference to the time to light
pots. Each grower must take into
consideration the kind of fuel as
well as the kind of heaters he IS us
ing and not permit the temperature
at any time to go lower than the
figures in these tables. either at the
lighting time or during the heating
operation Undoubtedly the greatest
heat effort will be required from day
break up to the time the tempera
ture is normally safe, and there is
no doubt but that the maximum
amount of smoke possible to secure
at sunup will save many frosted
buds. Fires should not be extin
guished until the normal tempera-
ture has reached at least 32 degrees.
The committee recommends that
for severe frosts or freezes special
in preparation and op-
Grafton is absolutely necessary to
secure desired results. We believe
that trees of good vitality will stand
more frost than those not so strong
and recommend that the grower do
not give up his heating operations
because after frost much OF the
bloom is brown and apparently KILL
ed We believe that much OF the
bloom that appears brown may pos
sibly develop fruit and. unless the
bloom is black and beyond possible

fled in continuing his heating opera |
tions after damage may have occur /
red in his orchard. The question of
how brown blossom must be to-
preclude any possibility of develop
ing fruit Is as uncertain problem |
at the present item as any other one
in connection with orchard heating.
One mans Judgment on this point
is fully as good as another's, and We,
therefore, recommend that the grow
err after having heated his orchard
for one or more night and Is still IN
doubt as to the condition of his
crop, should continue his heating op-
erations until he is convinced that
he has no crop.
We also recommend that the
growers exercise the greatest care in
selecting and testing their thermom-
eters and in properly placing them
in the orchards, and exercise great
care in their use during the heating
Thermometers should
be placed at least one to each 5-aere
tract and at a point level with the
lowest fruit on the trees, taking the
average of the tract. Also one good
instrument outside the orchard and
entirely away from any artificial
heat.
We believe that on the average
during the past seasons many or
chardists have not lighted their
heaters as early or as quickly as they
should. Likewise We believe many
growers eNtinguished their fires in
the early morning before the period
of danger had passed. as a result
of not carefully watching their
thermometers.
We believe maany growers have
suffered great damage to their
crops even though they have at
tempted to heat, this damage the
result of a large amount of indif-
ference and skepticism. We would
recommend that unless the grower
supplies himself with ample equip
ment, making careful preparation
with reference to every detail and
supplying a surplus quantity of fuel,
after which most painstaking and
careful attention be given to the
heating operation, that it is a useless
expense on his part excepting in the
event of mild degrees of frost
The committee suggests to each
individual grower that this commit
tee is appointed for the purpose of
assisting the growers in every man
ner possible in the way of supplying
