LETTER OF SUBMITTAL. 



U. S. Department of Agriculture, 



Division of Soils, 

 Washington, D. C, June 24-, 1901. 

 Sir: I respectfully submit herewith the manuscript of a report pre- 

 pared by Mr. Thomas H. Kearney and Dr. Frank K. Cameron to throw 

 light upon problems encountered by the field parties of the Division 

 of Soils in the soil survey of certain areas in the West affected with 

 alkali. As this is treated largel}^ from the physiological side, it seems 

 proper that it should be transmitted by you for publication. 

 Respectfully, 



Milton Whitney, 



Chief of Division. 

 Mr. Albert F. Woods, 



Chief, Diinsion of Vegetable Physiology and Pathology.
