APPENDIX. 



Results of the Examination of Sugar-beets raised on the College 

 Farm during the past season. 



The percentage of sugar was ascertained by means of a polar- 

 ization apparatus, and the results obtained, in several instances, 

 verified by Trommer's test. My thanks are due to Mr. J. E. 

 Heyl, of Philadelphia, for kind assistance rendered in the labor- 

 atory work during his stay as special student in chemistry at 

 the Agricultural College.
