26536. Medicago sativa L. Alfalfa. 



Presented by Mr. D. S. Elder, El Centro, Imperial Co., Cal., through Mr. Charles 

 J. Brand. Received December, 1909. 



"This alfalfa is ordinary American alfalfa and was grown 3 miles west of Brawley 

 in the Imperial Valley of California from seed secured by Mr. Elder from his brother in 

 Wyoming. It was grown in a loose, sandy soil on a field which was without water from 

 April, 1906, until May, 1908. The ditch which supplied this field was dry dining this 

 period on account of the Colorado River breaking through its banks and flowing into 

 the Salton Sea. No records of rainfall are available for Brawley, but it is estimated 

 that the precipitation for the two years was about 2 inches each. Part of this alfalfa 

 was cut and part pastured during the time that it was without water. The present 

 sample should be of use in selections for drought resistance. ' ' {Brand. )
