With reference to the last question, it may be here noted for 
the information of the members and friends of the Garden that 
Dr, Olive is a collaborator in plant disease work, and Dr. O. E. 
White in plant breeding, with the Bureau of Plant Industry, of 
the U. S. Department of Agriculture. In this connection, Dr. 
Olive has, among other activities, made a trip to the Mexican 
border (see pp. 154-158 of this issue) to make a survey of 
Fic. 12. Cycas circinalis. Near view of plant shown in Fig. 11. The 
terminal staminate, or “male,” cone measured 24 inches from tip to stalk.
