the plants have about a dozen leaves, the second being made just 
before the plants commence to head, even though but few or no | 
worms are to be seen at the time. 
Usually for lettuce only one application of the resin lime mix- 
ture will be required, at least if combined with hand picking. 
For lettuce the following proportions must be used:

This is not recommended as one of the best measures to be used 
for the protection of lettuce. We still believe that the proper use 
of mosquito netting would prove the most satisfactory even if a 
trifle the most expensive. The use of resin lime mixture is sim- 
ply offered as a substitute that has been tried; a substitute to be 
used after a house has become infested. 
When the fact is taken into consideration that with one appli- 
cation of resin lime mixture on cabbage and cauliflower two pests 
are disposed of, the expense of using it even as a preventive 
measure is slight. Probably the cost of spraying cannot be 
reduced much below the estimated amount, viz., about $1 per 
acre for each application even with added improvements, for the 
following reasons: First, a knapsack, or a barrel sprayer must 
be used. No power sprayer will do the work thoroughly on 
either cabbage or cauliflower. Furthermore, cauliflower heads so | 
unevenly it would not only be impossible but unsafe to spray it 
with a power sprayer. Second, only intelligent and skillful labor 
should be employed to do the work. It is essential, for both the 
cabbage worm and for the looper, to get the mixture on the outer 
and under surface of the leaves, as well as on the upper surface. 
Furthermore, the workman must be familiar with the habits of 
cauliflower, able to tell at glance whether the whorl of leaves 
at the center is opening so as to expose the flower. Such plants 
must not be sprayed. } ,
