constitutional. Pay these men ana ies

their beautiful citrus groves
THE RBMEDIEs.
rolonel HolGster. of Santa Barbara, has
baen irving for q number Of years to eradl-
cate the nest from his orange grove. In
many of his experiments he was only par
t;aIly successful At the present time ne
hos lines of water pipe laid through ms
GROVE and is washing the trees with wafer
Ts;nr a three-eighths of an inch nozzle,
with a pressure of 2S1 pounds to the square
;nch or eoual to a head of Go feet. That
bo can prevent its spread by this means
there is no doubt, but whether he can Ell
fect,ially clean the trees can only be learned
as the result of his experiment. VISITED
his grove last month, IN company Win ..
p. Stowe. 1 noticed a marked Improve,
ment in the grove. Mr.. Stowe expressed
himself satisfied that the ColoneIs plan
was practical, and, before l left Santa Bar
bara, had partially decided to lay pipes ana
use water on his citrus trees for destroying
the pest.
EXPERIMENTS.
During my stay in Santa Barbara l made
some experiments which SO far as destroy
pertinent No 1 A solution made OF one
pound of whale oil soap and sulphur mix
ture to each gallon of water used and one
pound of buhach added to every fifteen gal
Ions of the solution, destroyed all OF the
insects that it came in contact with on the
leaves and branches, but did not penetrate
the egg cases except where they were
! broken by the force Of the spray. Expert
ment No. Q: A solution of whale oil soap
mixture as above with one pound OF buhach
and one gallon of coal oil added TO sixteen
gallons of the solution proved very effective.
| Experiment No. 3: Half a pound OF COM
mon brown soap (whaie Oil or soft soap
will do as well) boiled i'll one cation OF
water. When boiling pour into two gal
! Ions of coal oil, then churn through q
small force pump from ten to fifteen min
| utes this will form q creamy, then add
! Twenty-Five gallons of water, in which is
| dissolved say twelve and a half pounds OF
whale-oil soap, or strong soft soap. This
will destroy the moving insects and Will
penetrate the case and destroy the eggs
! This solution Of coal oil was tried without
adding the twelve and half pounds OF
soap, but did not spread on the leaves to be
n sufficient success. Half pint Of coal oil
TO each gallon of wash mixed above will
not injure the fruit or foliage of citrus trees
| GENERAL REMARKS.
In July the cases Tor white portion) arc
filed with eggs and newlyhatched young
In washing it is necessary to use yer
strong spray, so as to break the case. In
soap, if properly applied, will destroy the
young, and the coal oil viii destroy the
eggs: but where there are many OF the
! young (larvG) and grown females on the
foliage and branches, which is in August
and September although it is more costly,
the addition Of buhach makes the work
more effective.
Pruning In many cases at San Gabriel
it was necessary to cut off all the branches,
then wash the trunk with lye, etc. In all
cases where trees are infested by this pest
the branches should be thinned out. and
those taken ont burned. A band of old
sacking should be placed on the trees, SO
as to prevent those falling on the ground
from returning up the trees. If strong
| spray is used, so that the cases can be
broken up in July, then the trees well
thinned out, and pruning burned, second
washing in August will be effectual.
Result; Thorough work will eradicate
| the pests, or in other words, dollars and
cents properly expended will return five
| fold. But if any work is done that is not
| thorough, successful results are doubtful.
N. B.: Tobacco has been used i'll the soiu-
! ton with reported success.
