striped cucumber beetle Diabrotica vittata (Fabr.). The experiment 
was tried on quite an extensive scale, but the results showed the 
expedient to be at best of doubtful value. The attacks of the 
cucumber beetle were not serious at this Station the past season, 
but many of the insects were found in immediate proximity to the 
bean plants. |

A Traut oF Host Nozzzes. 
The importance of some efficient spraying apparatus for dis- 
tributing insecticides is becoming more and more appreciated by 
gardeners and fruit growers. As the success of any apparatus 
depends largely upon the nozzle used for distributing the lhquid, 
and as several different forms of this necessary appurtenance have 
recently been placed upon the market, it was thought advisable 
to make a comparative test of the kinds that have been specially 
recommended for insecticide work. 
The Climax nozzle, furnished by the Nixon Nozzle and Machine 
Company, of Dayton, Ohio, forces the stream through a disk of 
brass wire cloth, which breaks the jet into a spray of which the 
fineness is made adjustable by varying the mesh of the wire cloth. 
Where a sufficient head of water is available, this nozzle is capa- 
ble of making a finer spray, considering its volume, than any other 
I have tested. For trees of medium size it must be regarded as 
one of the best. By removing the section containing the wire- 
cloth disk, it throws a constant stream and may be used as an 
ordinary hose nozzle. 
Three forms of nozzles were tested that are designed to furnish 
a spray. which may be adjusted to suit all kinds of work. One of 
these was the “ Graduating Spray ” nozzle, sold by the Field Force 
Pump Company, of Lockport, N. Y. The other two were the 
“Lowell Improved Spray Nozzles,” Nos. 1 and 2, received from 
Mr. A. Hallowell, Lowell, Mass. For producing a moderately fine 
spray, and especially one that is projected to a considerable dis-
