 the farmer to supply the kind and amount of plant- 

 food required for the production of a special crop for a 

 special purpose/ 



In an appendix to the report are presented photo-

 upon the College farm and the sugar content of the 

 same. 



Second Paper. Report on sugar beets raised upon 

 the College farm. (Ninth Report of the Massachusetts 

 Agricultural College, 1872.) 



This paper gave the results of his own experiments 

 in the field and laboratory along three distinct lines: 

 (a) methods for producing good sugar beets in accord- 

 ance with the rules stated in his previous report; (6) a 

 study of the chemical properties of the sugar beets 

 grown on the College farm, with reference to their fit- 

 ness for beet-sugar manufacture; and (c) a study by 

 actual tests of the amount of sugar available for com- 

 mercial purposes. 



The paper described in detail the selection of soil, 

 method of planting, care of the crop during the growing 

 period, and method of fertilization. He also discussed 

 the effect of potash salts on the basis of German inves- 

 tigations. He further presented data relative to the 

 weights of the different varieties of beets grown upon 

 the College farm and their sugar content at different 

 stages of growth; also the amount of nitrogenous sub- 

 stance and ash contained in the juices. In the process 

 of extracting the sugar he followed, on a small scale,
