110 SUGAR BEET SEED. 



The reception-room during a day's working in the 

 present case is filled and emptied five times. Each 

 beet of any division or series has a number, which it 

 retains during the entire manipulation of the sample 

 in the laboratory. Before being taken to the sample- 

 room, it is weighed on an ordinary spring scale, no 

 great accuracy being necessary; it is then placed in 

 the pigeonhole, waiting its turn, as not more than, 

 one-fifth of the roots are retained during the early 

 periods of selection; for one day there would remain 

 but 800 individual beets of the 4000 analyses made. It 

 is important, after the sample is taken from the root, to 

 fill up the hole made with clay or wood charcoal. The 

 mothers are thus in a measure protected against rot, 

 etc., even after several months in the silos. 



After the chemical selection has been completed, 

 the beets are placed in special silos until the planting 

 season. The help needed for 2500 to 3000 analyses 

 per diem with one polariscope having a continuous 

 tube attachment, using the Keil and Dolle rasp, accord- 

 ing to Pellet, is as follows:

If it is intended to analyze '4000 to 5000 beets per 

 diem, an extra rasp would be needed. There would 

 be required about seven or eight additional hands: 

 Rasping, i; weighing, 2; filtering, 3; to accom- 

 plish nearly double the work. These analyses may be 

 made for about one cent per beet examined. By the 

 Hanriot method, the weighing being done away with.
