Along outlet of chain of small 
lakes in the noted lake district of 
Northern Wisconsin, affording un- 
usual opportunity for water supply 
and control, producing fruit in nat- 
ural state. 200 acres in tract, about 
half available for cranberries, bal- 
ance for general cultivation and at- 
tractive lakeside residence.

black with a conspicuous yellow ab- 
domen while the male is much 
smaller with a darker body. 
With the first real warm days of 
spring the adults emerge from their 
winter cocoons and as soon as the 
first leaves expand, whitish eggs 
are laid end for end in rows along 
the main veins on the underside 
of the leaves, principally those 
nearest the base of the plants. 
The eggs soon hatch and the de- 
structive work of the worms be- 
gins. The larvae are conspicu- 
ously marked with black spots and 
are well enough known by garden- 
ers to need no description. The 
life cycle is repeated in the sum- 
mer making two broods a year. 
How to Control the Currant 
Worm.— The larvae are very easily 
destroyed by applying a spray of 
arsenate of lead 1 to 144 pounds 
in 50 gallons of water (5 or G level 
teaspoonsful to a gallon). If the 
bushes need to be sprayed when the 
fruit is nearly mature, fresh helle- 
bore should be used at the rate of 
4 ounces to 2 or 3 gallons of water. 
The application should be made as 
soon as the young worms make 
their appearance.

Control Measures for the Cabbage 
Worm. 
The cabbage worm comes from 
yellowish to orange yellow colored 
eggs laid by the common white cab- 
bage butterfly. It annually causes 
serious injury to cabbage and cauli- 
flower. This pest may readily be 
controlled by the use of arscnicals. 
The best results are obtained by ob- 
serving the following points. 
1. Spray the plants when the 
worms first hatch. Don’t wait un- 
til the plants are badly injured. 
2. Repeat the spray, if neces- 
sary, to cover new leaf growth and 
to kill the worms hatching from 
eggs laid later in the season. The 
eggs for the second generation are 
usually laid about the early part 
of July and for the third genera- 
tion about the early part of August. 
3. Use a “sticker” such as laun- 
dry soap in liquid sprays to make 
them stick and spread better on the 
smooth, waxy cabbage leaves. 
4. Apply the spray in the form 
of a fine mist so that the foliage is 
thoroughly coated. 
5. Keep spray material well agi- 
tated so that it will not settle to the 
bottom of the tank. 
G. Pour spray material into tank 
through a strainer to prevent clog- 
ging the nozzle. A curd-like pre- 
cipitate often forms when soap is 
dissolved in hard water. 
ARSENICAL SPRAYS. 
Calcium arsenate, lead arsenate 
and paris green all give satisfactory 
control. They should be used at 
the rate of one pound of the powder 
to fifty gallons of water in which 
one oi’ more pounds of common yel- 
low laundry soap ‘has been dis- 
solved. When using hard water, 
more soap is required as the hard 
water causes the soap to curdle. 
Soft water should be used where 
available. 
The sprays may also be dusted 
on the plants early in the morning 
when these are wet with dew. 
When so used, they may be diluted 
with from 5 to 10 parts by weight 
of lime.
