Professional Advancement Service 
The Professional Advancement Service seeks to aid men and women in 
botany and related subjects in securing such positions as they may desire, and 
to offer to heads of departments, or directors of laboratories, experiment sta- 
tions, or other institutions an opportunity of making known the vacancies they 
seek to fill. 
The method of the service consists in publishing in the American Journal 
of Botany a brief notice stating the training and experience of the applicant 
or the requirements of the vacancy. Each person using the Service is desig- 
nated by number and his identity may be learned on application to the Business 
Manager of the American Journal of Botany. A list of eligibles and open posi- 
tions is kept, and inquiries are referred to the advertisers who are mentioned or 
sieem best suited to the requirements stated. The Professional Advancement 
Service may thus have the opportunity to mention a man for a desirable posi- 
tion or a promotion a number of times during a period of several months. The 
charge for the service is $2.00 for each case for one year or less. The notice 
regarding qualifications offered or desired will be published at frequent inter- 
vals, but not more than ten times.
