container in order to kill this pest Plant lice. or aphids. are small,
 softbodied insects of various color, but
 usually green, black or red. This pest causes injury to plants by sucking their juices and drying them up, us-
 ually preferring the under side of the
 leaves. The lice are very prevalent,
 especially on potatoes, celery, beets.
 carrots, beans, spinach and lettuce
 The winter is passed in the egg stage
 These hatch in early spring and from
 that time until fall there are many
 generations. As soon as injury is
 noticed in the early summer, sprav
 the under sides of the leaves with
 whale oil soap. one pound to five to
 elght gallons of water, or black leaf

 phate containing 40 per cent nicotine
 This may be obtained at any reliable

 The squash vine borer is likely to
 ly all cucurbs. Usually the first in
 dication of this pest is the witherihg
 or drying of the leaves and if an ex-
 animation is made the bore will prob ably be found near the base of the
 injured parts. The adult of this in sect which is a clear winged moth appears early in July and the eggs are laid upon squash plants. The eggs hatch in the course of two weeks and the younger bore into the stems and feed until full grown. They then make their way into the ground where they pass the winter, transforming to moths the following spring. Insecti- cides are useless against them. Rake up and burn all vines as soon as the crop is gathered This will destroy any borers which might be left in the vines Late fall blowing will destroy many of the insects.
 The eggs of the squash bug are laid upon the under side of squash and melon leaves. They are of a brownish color and about the size of a pinhead The eggs hatch in two weeks and the young suck the juices, becoming ma ture in about a month. There are several broods each year. The bugs like to get into protected places at night. Shingles or pieces of board placed along the plants will serve this Turn over the pieces of board early in the morning and kill the bugs under them. The adults are very tough and may be destroyed onlyI by contact insecticides used at such strength as would be injurious to the may be destroyed by the use of whale oil soap, one pound to five gallons of water or any other contact poison | as possible after the crop is gathered. l
