but as yet he will have to lend a helping hand or'fail to gather a 
bountiful harvest. 
REMEDIES. 
As the eggs are mostly deposited upon the outer surface of the 
leaves, and the Vorms feed for some time before reaching the head, 
these insects may be nearly all destroyed by the prompt application 
of anv one of several good remedies. 
Among the cheapest, most easily applied, and, to our mind, the 
best of the remedies to destroy cabbage worms, are the arsenites, 
London purple or Paris green. We have given abundant proof of 
the harmlessness of such applications to those who eat the cabbages, 
in Bulletin 12 of the Iowa Experiment Station. 
Thoroughly mix one ounce of the poison in six pounds of 
flour, and dust it very lightly over the plants from a cheese-cloth 
sack in the evening or early morning, when a little dew is still upon 
the leaves. The first application should be made soon after the 
plants are set out. Certainly, no one can think that there would be 
the slightest danger in making such treatment up to the time that 
the heads begin to form. After the heads have formed, the poison 
can be applied mostly to the outer leaves ; but if any is put upon 
the head itself it is almost impossible that it should do harm, as the 
surface leaves of the head are not eaten, and these leaves in a grow¬ 
ing cabbage are continually spreading and becoming outer leaves. 
Neither can the poison be washed by rain into the cabbage, for the 
outer leaves do not run into the head. I should not think it advis¬ 
able to apply the poisons nearer than a week or ten days to the 
time of harvesting the cabbages, and it would never be necessary to 
do so. 
Patent insecticides, such as Slug Shot and Oxide of Silicates, 
have been much used by gardeners for the destruction of cabbage 
worms. The poison in these insecticides is Paris green, but no one 
ever heard of a person being poisoned from eating cabbages thus 
treated. These patent insecticides are much more dangerous to use 
than one a person prepares himself, for he is usually ignorant as to 
the composition of patent compounds, and is more liable to be care¬ 
less with them. 
For those who prefer not to use the arsenites, there is probably 
no better remedy than insect powder, or Buhach. This substance 
kills by coming in external contact with the worms, and is best 
applied by means of a blower that sends the fine particles of dust 
down between the leaves of the plants. 
This powder is not poisonous to man, and hence is very safe to 
use or to have in the house. The chief objection to this substance 
is its expense. Buhach may be purchased directly from the 
Buhach Manufacturing Co., Stockton, Cal., at 60 cents a pound.
