very thoroughly. To this end a pres

plying the principal formulas are
detailed below. This is information
that will be of value to our reader
throughout the crop-growing sea-

One can hardly undertake to store
this sort of informatino in the mind
for an indeterminate period of time.
Frequent reference to the printed
formulas IS the safest and wisest
Homemade Concentrated Lime
Sulphur Solution. The spray is used
for San Jose scale and is made as
follows:
Sulphur, flowers or flour, so lbs.
Lime, fresh and unslaked, 40 lbs.
Water, so gallons.
Stake the lime. mix in the sui
phur with it, add required water, and
boil for so to so minutes. Some of
the water will evaporate in boiling.
This should be replaced so as to
keep the amount at so gallons.
This formula is for making so
gallons of concentrated lime-sulphur:
When properly diluted this will
make from 800 to 400 gallons of
material for dormant spraying, or
1900 to 1000 gallons for the sum-
mer spraying of apples. To put it
another way, so gallons of the con-
centrated lime-sulphur will make
year-old peach trees, for San Jose
scale, or 800 to 500 ten-year-old APP
pie trees in foliage.
Diluted Concentrated LimeSu1-
phur. In making concentrated lime
sulphur at home there will be some
variation in the solutions. The va
ration can be corrected when dilut-
ing with water; To get the proper
dilutions, a hydrometer and the d.
luton table following should be
used. If these two things are not
at hand, use I gallon of the home
made concentrated lime-sulphur with
or gallons Of water, for DOR
mant spraying on apples and
peaches for scale. For summer
spraying of apples, use 1 to 1 IL
gallons to make so gallons Of the
diluted spray.
A hydrometer will cost from $1.00
to $3.50. The hydrometer best suit
ed is one that is scaled from to
SO degrees Baume, or from 1000 to
1880 specific gravity. If such an in
strument can not be obtained from
local drug store it can be had
from most any wholesale drug store.
Lime-sulphur solution should not
be confused with the self-boiled
lime-sulphur. Although they are
made from the same materials, their
uses are somewhat different and in
the substitution Of the 1ime-sulphur
solution for the self-boiled lime
sulphur. there is danger of doing
serious injury. Lime-sulphur solu-
ton is made by boiling the lime
and sulphur together in water. The
lime and sulphur under these condi-
tons, combine to form compounds
soluble in water. This solution is
caustic and if used too strong will
burn apple and peach foliage.
Besides the liquid commercial
lime-sulphur which may be purchas-
ed on the markets there is now
dry commercial lime-sulphur obtain
