LETTER OF TRANSMITTAL 



U. S. DEPARTMENT OF AGRICULTURE, 



BUREAU OF CHEMISTRY, 

 Washington D. C., April 1%, 1905. 



SIR: I have the honor to transmit herewith the manuscript of a 

 report on some studies made in the division of foods and in the micro- 

 chemical laboratory of this Bureau on the development of apples, espe- 

 cially under different conditions of storage, and to recommend the 

 publication of the same as Bulletin No. 94 of the Bureau of Chemistry. 

 This investigation has been in progress for the past two years, and 

 some preliminary work was done prior to that time by Mr. J. S. Burd. 

 The work was originated, planned, and directed by Mr. W. D. Bige- 

 low, chief of the division of foods. The analytical and bibliographical 

 data should be, for the most part, accredited to Mr. H. C. Gore, 

 though Mr. E. M. Chace and Mr. W. L. Dubois participated in the 

 analytical work. The third section of the report, comprising the 

 microscopic'studies, photographs of the fruit, and the specific gravity 

 determinations, is entirely the work of Mr. J. B. Howard, chief of 

 the microchemical laboratory. 



The investigation has been made in collaboration with Messrs. 

 William A. Taylor and G. Harold Powell, of the office of pomological 

 investigations, Bureau of Plant Industry, who have selected and pro- 

 cured the samples and furnished facilities for their transportation and 

 cold storage. They have also taken an active interest in planning the 

 work and discussing its results, and have furnished all of the pomo- 

 logical data. 



Very respectfully, 



H. W. WILEY, Chief. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
