LETTER OF TRANSMITTAL 



U. S. DEPARTMENT OF AGRICULTURE, 



BUREAU OF CHEMISTRY, 

 Washington, D. C., August 82, 1904. 



SIR: I beg to transmit for your inspection and approval a manuscript 

 containing the results of certain investigations on the chemical compo- 

 sition of tropical fruits. Aside from the scientific interest of this 

 study the principal object kept in view has been to make such a pre- 

 sentation of the facts of the case as may be of value to the citizens of 

 the possessions of the United States lying within the Tropics. The 

 cooperation of the expert of the Bureau of Plant Industry in charge of 

 tropical agriculture was secured in the identification of the fruits, and 

 the manuscript has received his approval in regard to all points in 

 which the investigation touches upon the strictly pomological phase of 

 the study. I have the honor to recommend that this report be pub- 

 lished as Bulletin No. 87 of the Bureau of Chemistry. 

 Respectfully, 



H. W. WILEY, Chief. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
