the manure used. When the seed is sown in the open ground, as practised
by many large growers, an extra quantity should be used to ensure
against almost certain loss of some of the plants by the flea beetle.
The soil should be rich and fine, so that the plants will pass the
critical stage as quickly as possible. Sowing radish seeds with the
cauliflower is practised by some, as this seed costs but little, and the
radishes, coming up first, are attacked by the fleas, which, to some
extent, saves the cauliflowers. When the fleas appear, almost any kind
of dust will keep them in check somewhat. Lime and ashes are used, but
plaster, which adheres to the leaves better, seems equally good. I have
had good success with rancid fish oil, mixed as thoroughly as possible
with water and sprayed upon the plants. An emulsion made of the oil, in
the same manner as hereafter described for kerosene, would enable it to
be used to better advantage. A decoction of tobacco, or fine tobacco
dust, are standard remedies for this insect.
CUT WORMS.--Cauliflower plants being fully twice as valuable as
cabbage plants, and it being of more importance to have them started at
the proper time, it is necessary to give greater care to protect them
from cut worms. Absolutely clean land contains no cut worms, but such
land is seldom used on which to plant cauliflower. Sod land, which is
generally used, is nearly always full of cut worms. A multitude of
remedies have been proposed for this pest, but few of them are of much
value. The worms are most abundant and destructive in the latitude of
New York during the month of May. Fortunately, cauliflowers are usually
set out either earlier than this, for the early crop, so that they
become well established and out of reach before their depredations
seriously begin, or else, for the late crop, they are set toward the
last of June, after the worms have begun to pupate, and are no longer
troublesome. Until recently, digging and killing the worms by hand
seemed to be almost the only practical remedy. Of late years, trapping
the worms under bunches of grass or cabbage leaves, scattered over the
ground preparatory to setting the plants, has been successfully resorted
to. An improvement upon this method, recommended by the Entomologist of
the United States Department of Agriculture, is now in use, and gives
excellent satisfaction. It consists in poisoning with Paris green the
leaves used to trap the worms, so that
