Aided by the figures just, given and the table 

 which I give on page 89, those who cultivate the 

 sugar beet may ascertain the industrial value of 

 their crop. 



If therefore you have cultivated the sugar 1 KM- t 

 and wish to ascertain its industrial value, you must 

 take one root of the average size, or two roots one 

 large and one small, and scrape them in the direc- 

 tion of their length, so that if you do not scrape the 

 whole beet, the pulp shall -have been taken equally 

 from the head, the middle and the point. This pre- 

 caution is necessary to obtain a juice of the average 

 richness, for all parts of the beet are not equally 

 rich in sugar ; in fact it is well known that the 

 ttpper portions are poorer in proportion as the collar 

 is neared. This done, you place the pulp in a press 

 and you press it as much as possible ; you catch the 

 juice in a deep and narrow vessel and plunge in your 

 juice weigher, say the Beaume areometer : the point 

 of contact being noticed, you establish the degree. 

 Suppose you find 8 degrees and a half ; you wish 

 to have the Brix degree, the most rational of all, 

 you find in my table that 8 Beaum6 corresponds to 

 14, 42 Brix and that 9 corresponds to 16, 23 ; 

 between 14, 42 and 16, 24, there is a difference of 

 1, 82; halve this difference and add the half 0.91, 

 to 14, 42 and you have 15. 33 Brix corresponding
