It will be of interest to entomologists to know that the cotton fumigating plants 

 in Boston, constructed by the Bureau of Entomology, are now in active operation. 

 Over 1,200 bales of cotton have already been fumigated in the two plants now avail- 

 able. These plants, furthermore, are being rapidly enlarged so that ultimately their 

 capacity will be approximately 1,000 bales a day each. It is very satisfactory to 

 know that these plants are in successful operation, inasmuch as this large-scale work 

 has been hitherto on a somewhat theoretical basis. As previously noted, this work 

 represents the largest insect fumigating plants which the world has ever seen, and un- 

 doubtedly very much the largest investment ever made for this purpose. It is re- 

 ported that the fumigation plant at Oakland, Gal., to meet the needs of the port of 

 San Francisco, is again in readiness. In common with one of the plants in Boston, 

 this Oakland plant had a breakdown, not having originally been made strong enough 

 to stand the vacuum pressure. A similar plant is in process of construction at New- 

 ark, N. J., and probably before long there will be a plant of the same kind available in 

 New York City. Plants at other ports are also being contemplated; These are all 

 private concerns, and make a regular charge for disinfection. 



S. A. Rohwer, of the Bureau of Entomology, has recently designed and had con- 

 structed a small cage to be used to confine, under natural conditions, growing plants. 

 This cage is a bronze wire cylinder, the top of which is closed by a lid which fits on 

 like the lid of an ash can; the lower end is open and fits against the soil. The frame 

 is made of galvanized iron. The top and bottom ai'e bands two inches wide, with the 

 edges turned, and are held apart by three strips of one inch by one-eighth inch gal- 

 vanized iron which project six inches below the bottom of the cage so they can be 

 driven into the ground to hold the cage in place. The uprights are soldered to the 

 bands on the inside. The bronze wire is held in place by solder. The lid is a gal- 

 vanized iron band over the top of which is bronze wire. The cage is eighteen high 

 by fourteen inches in diameter. On one side is soldered a one and one-half inch screw 

 top which affords an easy way of introducing insects after the cage is in place. This 

 cage is very useful in experiments on insects working on living plants, as it is possible 

 to grow, under nearly natural conditions, clean host plants and to infest them with 

 kno\™ insects. At the Eastern Field Station it is known as the G type cage and is 

 used in studies on insects of the genus Evetria and its parasites. More information 

 concerning its construction or cost may be had through correspondence. 



Annual Meeting of Pacific Slope Branch of American Association of 

 Economic Entomologists 



The annual meeting of the Pacific Slope Branch of the American Association of 

 Economic Entomologists will be held in connection with the meetings of the Pacific 

 Slope Division of The American Association for the Advancement of Science at San 

 Diego, Cal., August 9-11, 1916. 



It is hoped that there will be a large gatheringand that all entomologists on the 

 Pacific slope will attend. It is especially desired that entomologists in other parts 

 of the country who anticipate visiting California will arrange their trips so as to be 

 present at this meeting. Further details in regard to the meeting and information 

 ■concerning the program can be secm-ed by addressing the secretary, Professor E. O. 

 JSssig, Umversity of California, Berkeley, Gal.
