ASSIGNMENT OF C.I. NUMBERS
 
 This is a reminder that C.I. numbers are assigned to selections, 
 genetic material, etc., only upon request of parties concerned, 
 except for varieties which are named and released for public use. 
 If you have materials that should be added to the world collection 
 maintained at Beltsville, please apply for a C.I. number and 
 submit seed to Dr. J. C. Craddock.
