The first question that arises is this: In what condition did the 

 samples for analysis arrive at the Experiment Station ? With but few 

 exceptions they arrived in very good condition, well wrapped and 

 securely tied. The majority of them were received in from one to 

 three days after being harvested and in good condition for analysis. 



The fairness of the samples. — Were the beets sent to the Station for 

 analysis of good average size and did they fairly represent the beets 

 harvested ? In the data sent in the circulars, we have the niunber of 

 beets harvested and also the total weight of beets harvested, less necks 

 and tops, in pounds. From these we obtain the average size, or 

 weight, of each crownless beet harvested. 



The whole sample received was weighed after removing crowns 

 and the average weight of each beet obtained. Now by comparing 

 the average weight harvested with the average iveight of beets in the 

 sample analyzed^ we can see with what degree of accuracy the samples 

 were taken. 



In 296 cases the average weight of the individual beets harvested 

 was 1. 1 8 pounds each. In the same 296 cases the average weight of 

 the beets sent for analysis averaged 1.18 pounds each. So it will be 

 seen that, on the whole, the sampling of beets was very well done. 



Preparation of the sample for atuilysis. — Each sample was weighed 

 before and after removing the crown in order to ascertain the loss or 

 waste that the beet sustains while being prepared for the sugar 

 factory. 



The sample thus prepared was reduced to a fine pulp by means of 

 a grater. If the sample was small all of it was pulped for analysis; 

 if of medium size half of each beet was analyzed ; in some cases only 

 a quarter of each beet was taken. In all cases where the whole beet 

 was not used, a longitudinal section the entire length of it was taken 

 for analysis as shown in figure 155 (next page). The pulp was at 

 once put into a piece of strong canvass and the juice pressed out by 

 means of a press capable of 'exerting a pressure of 2,000 pounds or 

 more. 



The necessity of taking a longitudinal section the entire length of 

 the beet would seem to be proved by the results of the. following five 

 experiments. 



Five samples consisting of three beets each {without croivns) were cut 

 in two, crosswise, so that the upper and lower halves of each sample
