more, there are a few days during which the beetles can be poisoned 
on the squashes; hence they are a valuable adjunct even where 
covers are used. 
None of the measures recommended thus far are as valuable 
when used alone as when several are combined together as was 
done in the field tests. Possibly the use of Bordeaux mixture and 
squashes would not be as economical in small gardens as would 
the use of covers and squashes. For growers of pickles and those 
who grow cucumbers for market, I would recommend the use of 
Bordeaux mixture on the cucumber vines and the use of squashes 
both as a poisoned bait and as a lure. Several rows of squashes 
should be planted around the margins of the field about four days 
previous to planting the field with cucumbers or melons, as the 
ease may be. If desired, the squashes can be put in drills a few 
feet apart, or even sown broadcast. At time of planting the 
cucumbers, make a second planting of squashes on the margins 
of the field. If the beetles are very thick, a third planting of 
squashes had better be made. As soon as the first beetles are 
seen around the squashes, about one-half of the latter, especially 
the outside rows, should be thoroughly dusted with green arsenite 
or any other form of arsenic that can be most easily obtained. 
Part of the squash plants should be left untreated, for the reason 
that a rain or heavy dew may follow the application of the poison 
and kill the treated plants before many beetles are killed. When 
the cucumbers are fairly up, they should be sprayed with Bordeaux 
mixture, using four pounds of copper sulphate and four pounds 
of quick lime to forty-four gallons of water, or what is usually 
designated as the 1-to-11 formula, for making the mixture. This 
mixture can be applied most cheaply, while the vines are small, 
with a knapsack spraying machine. At the time the cucumbers 
are sprayed, more of the squashes can be dusted with the copper 
arsenite. If possible, the arsenite should be blown onto all parts 
of the squash plant, the object being to allow the beetles not a 
particle of food that is not poisoned. After the beetles commence 
to pair, the squashes can be cultivated out, although it is well to
