Poisoning Pocket Cophers.'

Strychnia sulphate is the most conven-
lent form of the poison, since it is
freely soluble in hot water and in the
natural juice Of vegetables used as bait.

q pint of thick sugar syrup, and stir
thoroughly. The syrup is usually
scented by adding a few drops Of oil
of anise, but this is not essential. If
preserved in a closed vessel, the syrup
will keep Indefinitely.
The above quantity Is sufficient to
poison a half bushel Of shelled corn or
other grain (corn recommended), the
cereal being stepped in hot water and
allowed to soak ove night. It is then
drained and soaked for several hours
in the poisoned syrup. Before using,
corn meal may be added to take up the
excess of moisture.
Dry crystals Of strychnine also may
be used. They are introduced by
means Of a knife, into small pieces Of
potato, carrot, or sweet potato, or into

The prepared bats are placed in the
underground runways Of the gophers
and are conveniently handled with q
spoon. A stout dibble is used to make
holes into the runways. Having To-
Gated the rnnways by use Of the dibble,
It Is moved from side to side to make
the soil firm about the hole, and then
withdrawn. A piece Of the poisoned
potato or raisin or a teaspoonful of
the poisoned corr is dropped into the
hole which is left open. Some farmers
prefer to cover the holes, but the exper-
fence of tho Agriculture Department
rs against such practice.

should be placed in the main runways
and not in the short laterals near the
