Mr.. A. F. Conrad, entomologis
Of the South Carolina Experimen
Station, has given the following in
FORMATION and directions for far
mers concerning the Jose scale
which is SO Injurious to fruit tree
In cotton sections:
The season is rapidly approacchi1.
when we must be seriously COZ
sidering the question of San Jos'
scale control. It is with winte,
sprays only that this pest can b.
brought under subsection, and these
must be applied when the trees are
dormant and leafess. 9lthough tn,
insect is very resistant and any spray
sufficiently penetrating to kill the IN
sect under the scale; if applied II
summer it would kill the tree. IL
This article we consider the essen.
tials of good spray pump and the
grades or ingredients. Blunderina

material may make spraying ex2ea.

In selecting spray pump the
orchardist must be governed by the
circumstances. Cheap tin or copper
pumps cannot be used for this spray
nor do We recommend knapsack
pumps for this purpose. A substi-
.ute pump with brass working parts
should be secured. 1t should b.
fitted with rs feet of hose, ant
in case of large trees an extension

In orchards of one hundred o
more trees. a barrel-pump, costint
from SIS to $40, is recommended
It may be fitted with two leads 0
lose, the barrel having a capacity O.
fifty gallons, thus economizing tins
and labor.
The 1-2-inch four-ply hose Is gen.
orally used. It costs about 10 to /:
cents a foot. The best quality hose
costs about Is cents, and is the cheap
est in the end. A wire-wound hose
although heavier, will stand NOR
