Of animal industry still favors the use
OF the lime and sulphur dip. although
much evidence has been brought for
ward TO show that Il Injuries the wool.

Prominent among The proprietary dips

certain preparations with tobacco as
the principal element in their potency
The following is the fomula for
making the lime and sulphur dip.
Take eight TO eleven pounds OF un-
slaked lime and add enough water 20
Stake the lime. sift into this three
times as many pounds of flower Of sui
phur as there were pounds OF lime at
the outset Boil the mixture from two
20 three hours. adding water when
necessary. Pour the mixture into "a
tub. vat or barrel that it may be
drawn of through a spigot without
sediment. When using this dip. 70 IS
greatly important TO keep the sedi-
meut out OF the mixture.
The common form OF the infection
known as sheep scab causes greater

as dipped the sheen should be removed
from their old surroundings and pas
ture grounds for a period OF at least
20 days. The eggs hatch in two or
three DAYS after they have been laid.
When the Cocks are small. says the
Orange Judd Farmer. the dipping may

galvanized watts made for the purpose.
