 Sir: I have the honor to submit for your approval three studies 

 on fruit respiration made by H. C. Gore of this bureau in cooperation 

 with the Bureau of Plant Industry. Mr. William A. Taylor, acting 

 chief of that bureau, has been in close touch with the work, making 

 suggestions from time to time which have increased its scope and use- 

 fulness. I recommend that this manuscript be published as Bulletin 

 No. 142 of the Bureau of Chemistry. 



Respectfully, H. W. Wiley, 



Chief of Bureau. 

 Hon. James Wilsox,
