Arsenate of lead — dry, powdered 1 lb.

ls | spraying except for potato beetles. Use it for caterpillars, worms.

J plants. 
Calcium Arsenate 
y 
This is a new insecticide which is being used to some extent in place 
e| of arsenate of lead. About half as much of the pure calcium arsenate 
ii is required as is needed of arsenate of lead. Much of this product on 
the market is impure and needs to he used with freshly slaked lime to 
prevent foliage injury.

Paris green is not recommended for general spraying on account of 
■ 
foliage injury but if well applied is sometimes preferred against the 
Colorado Potato Beetle on account of its strength. 
trees on his place pay for their 
lodging. After a short investiga- 
tion resulting in the discovery 
that the difference between profit- 
able and unprofitable orchards de- 
pended on a few days spraying, he 
purchased a spray pump and used 
it, according to the best advice he 
could obtain. He was no horti- 
culturist but found spraying di- 
rections more simple than he had 
expected and the returns even 
greater. His two seasons’ experi- 
ence have converted him to spray-

only a barrel outfit. 
Hellebore 
Tf you wait so long before destroying currant and gooseberry worms 
and similar insects on fruits and vegetables that there is danger in 
applying poison use fresh hellebore, one ounce in three gallons of 
water, or apply it dry. It is non-poisonous to higher animals.

Tobacco Solutions 
Forty per cent nicotine sulphate is by far the most satisfactory 
contact insecticide for plant, lice. The most common form on the 
market may now be secured from most seed dealers and many drug

Every owner of a small orchard 
can do as well. Apples make a 
good food for hogs but are not 
profitable used in that way. If it 
were possible to learn the num- 
ber of thousands of bushels of 
fruit wasted in Wisconsin every 
year the figures would be an eye- 
opener to the food conservationist. 
One of the subjects on the 
Farmers Institute programs the 
past winter has been, “Why buy 
apples? Better sell ’em.” Thous- 
ands of orchard owners can easily 
make their trees an asset instead 
of a liability just as many hun-
