however there are not sufficient birds
to do this.
The pecan grower who has ten
acres or more of bearing trees will
find it advisable to have a power
outfit. In selecting power equipment,
the following points are of value:
IA tank that will hold a large
quantity of water. A 200-gallon tank
seems to be about the right size. 1t
SHOULD be equipped with an agitator.
2-The pump should be Of simple
construction so that all parts can
be easily gotten to.
3-The engine is the most trouble
some part of the power outfit to get
to do it's work properly and con-
stantly. Some of the points to be
desired In a gasoline engine for a
constant pressure of 200 pounds with
some reserve power left; ability to
stand hauling about the orchard
without getting out of adjustment;
and construction on simple lines.
flank, pump, engine, wagon and
quired. At least two leads of hose
will be needed for each power outfit.
The length of these will be deter
mined by the size of the tree to be
sprayed. If the trees are twenty-five
feet high each lead will need to be
about forty feet long. Cut-offs and
extension rods are necessary. The
cutoff is fitted into the extension just
where the hose connects with the ex-
tension rod.
5-If spray guns are used trees
thirty feet high can be sprayed from
the ground. Spray guns require over
200 pounds of pressure. The nozzles
must convert the flowing stream into
spreading mist. A good style of
nozzle is a simple disk.
6-Another part of the outfit that
is important is the pressure gage. To
regulate the pressure, a valve is used
in the return pipe. AS the pump
draws the material from the tank, all
that does not pass through the noz-
zles returns to the tank. This regu-
lator is doing good work when it can
be set so as to give the same pres
sure whether the nozzles are working
or cut off.
For a few trees or a young or
chard, a barrel spray pump will give
good results if sufficient hand power
is furnished and the operation Is
There are many power sprayers and
barrel pumps on the market.
Protecting Beans from Weevi1s

The best method Of protecting the
beans you have gathered against In

proceed as follows:
Shell them as quickly as possible
and put them into relatively alright
containers. Large fruit jars will am

Then treat them with carbon bisul-
phide. You can secure small guam
tity of this material from drug

at the rate of about two pounds per
ton of beans to be treated: You Will

treatment of each jar of beans. Put

part of the container. 1t will eff

will need to repeat this treatment in
about 80 days so as to destroy any
weevils which may hatch later. If
you expose the beans to the air for
a few hours, the offensive odor. will
disappear and they will be found per-
fectly good and wholesome to use as
food. I should not prolong the treat
ment suggested for a period of more
than tWenty-four to thirty-six hours.
Carbon bisulphide will not injure the
clothes or burn the hands. 1t is cas-
lily inflammable in the presence of
light. so handle it in the day time
and out of doors.
