Dear Prof. Leopold: 
As discussed in our conversation this morning, we 
believe that under the regulations of the Soil Conservation and 
Domestic Allotment Act the following combinations are to be construed 
as "soil conserving crops": 
(1) Legumes planted under a nurse crop of thinly 
sowed buckwheat, wheat, barley, or wheatland 
milo. Such nurse crop may be left on the ground 
uncut as food for game. 
(2) Perennial grasses planted under a nurse crop of 
thinly sowed buckwheat, wheat, barley, or wheat- 
land milo. Such nurse crop may be left on the 
ground uncut as food for game. 
(3) Sweet clover. (During the second winter sweet 
clover makes excellent game cover. It has little 
value as game food.) 
SincerelZ yours, 
W. W. LAM 
Assistant State County Agent Leader

P.S. We shall be glad to have you communicate this to Mr. Kingston 
And other varties who may be interest in this question.
