SUGAR BEET SEED. 



the prescribed limit of weight are taken to Table A, 

 consisting of a series of shelvings about six feet in 

 height. On each shelf there are compartments for 

 twenty beets; each has a number, to which is also 

 appended the number of the shelf. The rasping is 

 done by the two double rasps at Table C. The motor 

 for the rasps is shown at D. There are four small 

 scales, E, on which the cream-like pulp is weighed;' 

 the flasks are filled on the other side of the same table, 

 f, f, /'; the necessary distilled water and subacetate of 

 lead are obtained from reservoirs suspended from the 

 ceiling. The filtering tables are shown at F; the 

 funnels are all held in a fixed frame, while the glasses 

 receiving the filtrate are on tables with wheels, which 

 may run on tracks, 1 1 1 1; these each hold twenty 

 glasses, ten on each side. When the filtering is com- 

 plete, they in turn are run over to R, which con- 

 sists of two rooms with polariscopes, having a common 

 light, p. It is interesting to note, that as soon as the 

 sample is taken from the beet at Table C, it is returned 

 to its respective compartment at Table A. Consider- 

 able system is essential for satisfactory working. 

 The 50 c. c. flasks, when filled, are carried in wire 

 baskets, in series of ten, to the filtering tables. As the 

 variations of sugar percentage need be only between 

 the limits of 14 to 16 per cent, of sugar, no very great 

 accuracy is required for weighing pulp or filling flasks; 

 it can, consequently, be done with considerable 

 rapidity. After the analyses tables have left the chem- 

 ists' hands,-the beets which are not kept are taken from 

 the compartment of A. For 5000 analyses per diem, 

 28 persons are needed; this includes the overseer and 

 the boy to keep the laboratory clean. 



(c) 3. Analysis with a .Special .Sampler, Without 

 Weighing, as Adopted by M. Legras. 



This method depends upon the use of the 

 Haniiot machine, and also upon a sampler worked
