October 10 the Kleinwanzlebener variety was tested. One hundred beets were an- 

 alyzed as "individuals," and the mean results showed 14.7 per cent of sugar. 



A notable effect of the heavy rains and previous hot weather is observable in tht 

 sucrose readings of the last three varieties of beets analyzed. The falling off in the 

 sucrose was seen by comparing the readings on the given dates. 



Analyses of those varieties were not made immediately before the rains, i. e., about 

 September 26 ; otherwise, if a comparison were made with the " Elite" and " Knauer " 

 varieties, and it be supposed that the three former had madea similar increase in sucrose 

 that the two latter varieties had done between September 15 and 25, then the actual 

 falling off in sucrose in consequence of the rains would be much greater, which 

 doubtless was the case. 



Field B was left alone after the work already described, a sufficient number of 

 beets of each variety being left for further analytical examination at a later period in 

 the season, in order to observe whether any of, or all, the varieties recovered the 

 loss in sucrose before the season closed. 



October 13 an examination of the varieties upon a large scale commenced in Field 

 A. The work was conducted the same as in Field B, and does not require any further 

 comment.j 



Variety "Elite, "100 beets were analyzed as "individuals," and 200 were tested in 

 "tens." The mean results of the individual analyses showed 14.8 per cent of sugar. 



The 200 beets analyzed in " tens " gave the results recorded in Table V. 



The mean results of the analyses of the "Elite" variety, October 13, were: Mean 

 sucrose in juice, 14.5 per cent; mean purity, 84.6 per cent. . 



October 14 the " Knauer" variety was tested. The mean result of the analysis of 

 100 individuals gave 14.8 per cent of sucrose in juice. 



The results of the analyses of 200 beets in "tens " are recorded in Table VI. 



The mean results of the two sets of analyses of the " Knauer " variety, October 14, 

 were: Mean sucrose in juice, 14.8 per cent; mean purity, 88 per cent. 



October 15 the " Lemaire" variety was examined. 



One hundred " individuals " were analyzed separately, showing mean sucrose in 

 juice, 14.2 per cent. 



Two hundred beets were analyzed in sets of "tens," and the results are shown in 

 Table VII. 



The mean results of the two sets of analyses of the " Lemaire " variety, October 

 15, were: Mean sucrose in juice, 14.1 per cent; mean purity, 83.5 per cent. 



October 16 the "Desprez " variety was analyzed. 



One hundred beets analyzed "individually" gave the following mean result: 

 Sucrose in juice, 14.8 per cent. 



Two hundred beets analyzed in " tens " gave the results recorded in Table VIII. 



The average results of the two sets of analyses of the Desprez variety October 16 

 were: Mean sucrowe in juice, 14.4 per cent; mean purity, 84.6 per cent. 



October 17 the Vilmorin variety was examined. One hundred beets analyzed 

 separately gave the following mean result: Per cent sucrose in juice, 14.8. 



Two hundred of the same variety analyzed in " tens" gave the results recorded in 

 Table IX. 



The average results of the two seta of analyses of the Vilmorin variety, October 17, 

 were: Mean sucrose in juice, 14.6 per cent; mean purity, 84.9 per cent,
