Dear Prof. Leopold: 
The enclosed copy of my letter to Hartz- 
Thorell is self-explanatory, the necessity for which 
I regret. 
Shipment of rice as per letter appears to 
be the best, and indeed the only solution at this 
time. I hope that the possible substitution of rice 
varieties will be satisfactory with you, and that it 
will in no way interfere with the feeding tests. 
I shall do my best to get to you ample seed 
of the Jap and Early Prolific varieties for planting 
next spring. 
Very sincer y yours, 
LeE. Ye ger
