cal, 1 pound to 100 gallons of water. These baits
are distributed in small lots over the ground _before_ the plants are
set, the precaution being observed that the land is free for two or
three weeks from any form of vegetation. This will force the hungry
"worms" to feed on the baits, to their prompt destruction. A bran-mash
is also used instead of weeds or clover, and is prepared by combining
one part by weight of arsenic, one of sugar, and six of sweetened bran,
with enough water added to make a mash. The baits are renewed if they
become too dry, or they can be kept moist by placing them under shingles
or pieces of board.

=Flea-beetles= attack the plants soon after they are set, and their
injuries can be prevented by dipping the young plants before setting in
a solution of arsenate of lead, about 1 pound to 50 gallons of water, or
Paris green, 1 pound to 100 gallons. If this precaution has not been
observed a spray of either of these arsenicals used in the proportion
specified will suffice, repeating if the insects continue on the plants.
In the preparation of the spray a pound of fresh lime to each pound of
the arsenical should be added; or, better yet, Bordeaux mixture should
be employed as a diluent instead of water. This mixture has some
insecticidal value, is a most valuable fungicide, and is also a
powerful deterrent of flea-beetle attack, acting to a less degree
against other insects which are apt to be found on the tomato. In
applying any spray a sprayer costing not less than $7 is a positive
necessity.

=The Colorado potato beetle=, or "potato bug," sometimes injures
tomatoes, but not as a rule when potatoes are available. This suggests
the use of potatoes as a trap crop, planted in about three rows
completely around the field of tomatoes. The arsenicals used in the same
proportion as for flea-beetles will destroy the potato beetle. It is
necessary to keep the trap potatoes well sprayed to prevent them from
breeding on these plants and migrating to the tomatoes. Potato beetles
can also be controlled by jarring them from the affected plants into
large pans containing a little w
