water could be as intimately commingled with the oil during the 
process of application as is accomplished in the emulsion, the 
same end would be attained without the annoyances incident to 
forming and applying the emulsion, which are by no means incon- 
siderable, | 
Experiments in this direction were carried far enough to show 
that there are no mechanical difficulties in the way of atomizing 
kerosene and water at the same operation. To the Woodason 
atomizing bellows a small cup was attached directly in front of 
the fount for holding the liquid to be atomized. From this cup 
a very slender copper tube was passed through the side of the 
fount where it entered the larger tube that ccnducts the liquid 
from the fount to the mouth of the bellows. It then curved 
upward, passing through the center of this tube as far as the 
mouth of the bellows, where both came to an end at the same 
point. Kerosene was then placed in the added cup and water in 
the fount. On working the bellows the liquids are atomized 
together. The proportion of kerosene emitted will depend upon 
the relative diameters of the two tubes, but it may also be regu- 
latéd by the relative depths of the liquid in their respective founts. 
A better way would be to use but a single fount and to divide 
this into two parts, one for kerosene and the other for water. 
This would permit the mouth of the bellows to be brought nearer 
to the plant to be atomized. 
This apparatus was used on many plants in the green-house 
for the mealy bug and scale insect with excellent success. 
It was also used for the aphis on the apple and for the leaf- 
hopper on the rose. For these it was effective so far as the insects 
were within reach, though in one case when used on the apple 
tree the foliage was somewhat injured. Ina single test for the 
potato beetle it did not kill all of the insects. The susceptibility 
of the potato plant to injury from kerosene renders this method 
of treatment for the potato beetle of very doubtful value. 
Tae Bean PLANT AS A REPELLANT FOR THE STRIPED CUCUMBER 
BEETLE. 
Early in the present year an item was circulated in the agricul- 
tural press to the effect that common garden beans planted with 
the seeds of melons and other cucurbits had in certain cases
