ANALYSES OF SUGAR BEETS, 1905 TO 1910, 



TOGETHER WITH 



METHODS OF SUGAR DETERMINATION. 



INTRODUCTION. 



Many requests are received at this department for reports on 

 analyses of beets grown in different localities and also for information 

 as to the fitness of certain sections for growing beets. Many inquiries 

 are also received as to the best methods for the analysis of beets. 

 This report, including a resume" of the analyses made of beets grown 

 in various sections of this country throughout a period of six years, 

 and also a statement of the methods used for beet analysis, with a 

 discussion of their comparative accuracy, has been compiled to meet 

 this demand. 



As early as 1862 1 the Department of Agriculture became interested 

 in sugar-beet work, and for the past 30 years this bureau has been 

 engaged in the analysis of sugar beets and in making investigations 

 for the improvement of this industry. The following bulletins 

 have been published giving the results of this work: No. 3*, The 

 Northern Sugar Industry, 1883; No. 5*, The Sugar Industry of the 

 United States, 1885; No. 27*, The Sugar-Beet Industry, 1890; 

 Nos. 30*, 33*, 36*, 39*, and 52*, devoted to experiments with sugar 

 beets in the years 1890, 1891, 1892, 1893, and 1897; Nos. 64, 74, 78, 

 95, and 96, devoted to a five years' study of the influence of environ- 

 ment upon the composition of the sugar beet, undertaken in 1900 to 

 1904, inclusive. 



The bulletins marked with an asterisk (*) are out of print and are 

 not available for distribution; the others may be had on application. 

 Also, as a part of Progress of the Beet Sugar Industry of the United 

 States, published yearly as a special report of the Secretary of 

 Agriculture, there has been issued in the years 1897, 1898, 1899, and 

 1900 a report covering the analytical figures obtained in the analyses 

 of samples of beets for these years. Since 1900 there has been no 

 publication of results of analyses of beets made in the Bureau of 

 Chemistry other than those published in the study of the influence 

 of environment on the composition of the beet. Many samples 

 have been analyzed since that time.
