CAS needs abstractors for Russian literature Chemical Abstracts has an urgent need for abstractors who can read Russian in all chemical fields ex cept polymer chemistry. There is a particularly critical need for volunteers to abstract Russian lan guage publications on mineralogical and geological chemistry, fertil izers, pesticides, and plant-growth regulators. Abstracting assignments can be geared to individual interests and available time. Papers and patents for abstracting are provided along with directions for preparing ef fective abstracts. An honorarium of 10 cents per printed line is paid for abstracts as published in CA. If you would like to help, write to Dr. Russell J. Rowlett, Jr., Edi tor, Chemical Abstracts Service, Ohio State University, Columbus, Ohio 43210.
