LETTER OF TRANSMITTAL 



U. S. DEPARTMENT OF AGRICULTURE, 



BUREAU OF CHEMISTRY, 

 Washington, D. C., July 23, 1909. 



SIR: I offer herewith for your inspection and approval a manuscript 

 prepared by William B. Alwood, enological chemist in this Bureau 

 at my request, embracing studies in the use of pure yeasts in cidei 

 making, applicable to farm conditions, and in wine making. The 

 results of these studies are of the highest practical importance to the 

 fruit growers of this country in indicating methods whereby the char- 

 acter of the fruit juices and products made therefrom maybe improved 

 thus rendering fruit growing more profitable and the consumptior 

 of these products more beneficial. In order that the results of these 

 studies may prove of immediate practical benefit, I urge that this 

 manuscript be published promptly as Bulletin 129 of this Bureau. 

 Respectfully, 



H. W. WILEY, 



Chief of Bureau. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
