 THE WORK OF THE CHEMICAL DIVISION. 



BY A. L. KNISELY AND G. W. CAVANAUGH UNDER THE 

 DIRECTION OF G. C. CALDWELL, CHEMIST. 



The work of the Chemical Division has been carried along 

 lines very similar to those of a year ago. Samples of beets have 

 been received from several hundred farmers. In most cases 

 the samples were accompanied by reports of the experi- 

 mental plats. 



75- Apparatus used ifi the analysis of Sugar Beets. 



The first step in the analysis of sugar beets is to obtain a sample of 

 juice. This process is similar to cider-making. The beets are grated on 

 an ordinary grater, lying under the press. The pulp obtained, about one 

 pint, is put in the cylinder of the press and the juice pressed out flows 

 into the glass cup or beaker under the spout. The juice is then poured into 

 the tall glass cylinder at the left of the lamp. The temperature of the juice 

 must be found with the thermometer, which lies on the table in front of the 

 cylinder. The density or solid matter of the juice is next found by means
