LETTER OF TRANSMITTAL. 



U. S. Department ■ or Agriculture, 



Bureau of Plant Industry, 



Office of the Chief, 

 Washington, D. C, April 13, 1907. 

 Sir: I have the honor to transmit herewith a manuscript entitled 

 " The Relation of the Composition of the Leaf to the Burning Quali- 

 ties of Tobacco," by Dr. Wightman W. Garner, Scientific Assistant 

 in the Tobacco Breeding Investigations of this Bureau. 



This paper contains much information of importance to growers, 

 manufacturers, and tobacco breeders on points which have heretofore 

 been very imperfectly understood. I would therefore recommend 

 the publication of the manuscript as Bulletin No. 105 of the series of 

 this Bureau. 



Respectfully, B. T. Galloway, 



Chief of Bureau. 

 Hon. James Wilson, 



Secretary of Agriculture.
