SUGAR BEET SEED, 



foregoing in many respects after the first selection is 

 made from the sacks. The seed is emptied into special 

 pasteboard boxes covered with black paper. These 

 boxes are 13I inches in length, about 10 inches in 

 width, and i^ inches in height. The seed in these 

 boxes must be very evenly spread over the bottom, so 

 that only one layer is obtained. Samples are taken 

 with spoons, so as to obtain a sufficient quantity for 

 subsequent examination. The Maercker method is 

 among the most accurate and interesting (Fig. 50).

The samples from sacks are emptied into a special dish 

 with a cross-like opening at the bottom; this dish 

 fitting exactly into a second one. The seed should be 

 evenly spread out with the hand, exerting no pressure.' 

 The dish is then withdrawn behind, and there remains 

 in the under receptacle a lot of seed, arranged geomet- 

 rically, corresponding to the opening in the bottom of 

 the dish removed; from it are taken the final samples 

 for germination, etc.
