LETTER OF SUBMITTAL. 



U. S. Department of Agriculture, 



Office of Experiment Stations, 

 Washington, D. C. , January #, 1900. 

 Sir: In accordance with } r our request I send you herewith abstracts 

 of the accounts of investigations on tobacco, which have been pub- 

 lished by the agricultural experiment stations in the United States and 

 Canada. These abstracts have been prepared by Mr. J. I. Schulte, of 

 this Office, in accordance with nry instructions. Only in a few States 

 have the experiment stations undertaken tobacco investigations in any 

 thorough manner. In many cases their studies on this subject have 

 been incidental to other inquiries or have been distinctly minor pieces 

 of work. This will very largely account for the fragmentary character 

 of the work, as indicated in this summary. 



Respectfully, A. C. True, 



Director. 

 Prof. Milton Whitney, 



Chief of Division of Soils.
