The varieties "Elite " and " Knauer," in Field B, which were weighed first, and 

 which were also the first to be tested on a large scale in the laboratory, appeared to 

 have reached their maximum maturity. The Lemaire variety in the same field did 

 not appear so thoroughly ripe, and the other varieties were still further off. Conse- 

 quently, after September 24 the beets were left alone until October 6, no weighings 

 or analyses being made during, that interval. 



The varieties in Field A were quite mature at the time the weighings were made. 



The weighings given represent the maximum yield per acre of each of the varie- 

 ties in both fields. The utmost precision was observed in each operation, and the 

 results are given as being exact. Moreover the weighings were practically con- 

 firmed by the number of tons actually hauled from the fields when the whole of the 

 beets were gotten up. 



The analytical work, commencing September 21, began in Field B on the variety 

 "Elite." The plat of that variety was comparatively small, so that 100 beets were 

 analyzed individually and 800 in " tens," making 900 beets totally that were taken 

 to represent the sugar value of the variety. The analytical data ol the "indi- 

 viduals" are given in Table I. No selection of the beets was made, each one be- 

 ing taken seriatim in the row. The mean of analysis of 100 beets was 15.6 per cent 

 of sugar in the juice. The data obtained from the analysis of the 800 beets in " tens" 

 are given in Table II. 



The results of the analyses of the "Elite" variety, September 21, were: Mean 

 sucrose in juice, 15.7 per cent; mean purity, 84.6 percent. The variety analyzed 

 next in order was the "Knauer." From that variety 100 "individuals" and 620 in 

 "tens "were analyzed. The mean percentage of sucrose in the juice of the 100 

 beets analyzed separately was 15.7. (The full table is omitted to economize space.) 



The analyses of the 620 beets in "tens" are given in Table III. 



The results of the "Knauer" variety, September 22, were: Mean sucrose in juice, 

 15.4 per cent; mean purity, 84.9. 



September 25 the "Lemaire" variety was examined; 100 beets were taken for 

 individual analysis and 600 for analyzing in "tens." 



The 100 " individuals " gave the following results : The mean percentage of sucrose 

 in the juice of the 100 separate beets was 13.9. 



The 600 in "tens" gave the results recorded in Table IV. 



The average results of the two sets of analyses the "Lemaire" variety on Septem- 

 ber 25 and 26 were: Mean sucrose in juice, 13.8 per cent; mean purity, 81.2 per cent. 

 The "Lemaire" beets were not so mature as those of the "Elite" and "Knauer" va- 

 rieties, and as the condition of the remaining varieties appeared still further from 

 maturity no further analytical work was done until October 6. The weather of the 

 previous ten or fourteen days had been highly favorable, and the less matured varie- 

 ties were still improving. 



From the cessation of the analytical work on September 26 up to the recommence- 

 ment of the same, heavy rains fell. About 4 inches of rain were registered during 

 that interval, an abnormally heavy precipitation for that peason. The normal rain- 

 fall for October in that part of the State is very little more than 1 inch. Follow- 

 ing the period of hot weather (the twelve days from September 13 to 25, the mean of 

 the daily maximum temperature was precisely 90), and falling upon soil whose tem- 

 perature was over 70, the effects were likely to be unfavorable and perhaps disas- 

 trous. 



October 6 work was resumed in Field B, and upon the " Desprez " variety ; 200 beets 

 were analyzed individually, and the mean result of the analyses was : Sucrose in the 

 juice, 13.5 per cent. 



At the time (October 6) stated no beets of the Desprez variety were analyzed in 

 "tens." 



October 8 the Vilmorin variety was further examined, 200 beets being analyzed 

 individually, showing a mean percentage of sugar of 13.8.
