Dear i'lr. &to:

   In a telephone aonversation with Dr. ~lumenachein
yesterday afternoon, I received your request for detailed
information on the origin of the seed samples of
races of maize received by me from Mexico and grown in
Sorth Carolina.  The samples of seed of Chalquasw
iapaiote 'hico, Arrociblo Amarillo, and ChapalOt8
came from ths original col1ectionL   The other
sa!liples were derived from propagation, as ir:dicrted.

   I was very pleased to learn that you expect to
make several trips this spring to visit other
laboratories.   It will be intcrestFng for you rnnd
certainly leave impressions.   ;Jhen I see you in the
near future, we can discuss aspects of this.

5incerely your8,
