220 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 12 



nothing other than the oil was introduced and because the mixture was easily made, 

 simple and inexpensive. The anthracene-oil- treated soil was scattered around the 

 base of the plant to form a protecting collar, 1 gallon of the mixture being used to 

 about 200 plants. The rates used were 1 part of the oil to 20, 40 and 80 parts of soil 

 by measure. It was hoped to establish the upper and lower limits of concentration 

 that were effective and non-injmrious. The 1 to 20 mixture proved injurious to the 

 plants, as a number died as a result of the treatment. The results indicate that the 

 1 to 80 mixture may be stronger than necessary, as this treatment proved most 

 effective. Distillate was used in one test to thin the oil to facilitate mixing. The 

 treatments were applied as soon as the kale was transplanted. The results secured 

 with these treatments follow: 



As only a small amount of anthracene oil is necessary in the mixture and soil is a 

 satisfactory carrier, this treatment is cheap, readily prepared and easily applied. If 

 it proves as effective in succeeding seasons as it did in our experimental plots this year 

 it should come into general use

MEETING OF PACIFIC SLOPE BRANCH AMERICAN ASSOCIATION 

 OF ECONOMIC ENTOMOLOGISTS 



The annual meeting of the Pacific Slope Branch will be held in connection with the 

 State Fruit Growers' Convention, at the Citrus Experiment Station, Riverside, Cal., 

 May 28 and 29. 



This meeting has been set especially to accommodate the visiting Eastern and middle 

 West entomologists, many of whom are to attend this convention. Regular announce- 

 ments have been sent to all members living west of the Rocky Mountains. Earlier 

 decisions to hold this meeting at Berkeley or Pasadena have been changed in favor of 

 Riverside as stated above. 



A cordial welcome is extended to all visiting entomologists. They will find the 

 Citrus Experiment Station and the School of Subtropical Agriculture most interesting 

 and inspiring. The meetings and discussions can not fail to interest entomologists.
