BEET SEED PKODUCTION IN FRANCE. 241 



(i) The impurities (leaves, stems, stones, etc.) 

 must not be more than 3 per cent. 



(2) Moisture not over 18 per cent. 



(3) One hundred seeds should give in six days 

 125 sprouts. 



(4) After twelve days, with gradual heating, 100 

 seeds should give at least 150 strong and healthy 

 germs. 



(5) Of 100 seeds, at least eighty should germinate. 



(6) One kilo of seeds should give 70,000 sprouts. 

 Seeds may be refused if they contain more than 4 per 

 cent, impurities, and more than 17 per cent, moisture; 

 and if 100 seeds, after the two days, contain less than 

 140 sprouts, or if with normal moisture one kilo of 

 seeds gives less than 68,800 sprouts, and if 100 seeds 

 yield less than 76 seeds which sprouted. 



Example of Calculations of the Juice of Seed. 



If we suppose the seeds had been sold for eight- 

 cents per pound and that these seeds contain 4 per 

 cent, impurities, 15 per cent, moisture, and that 100 

 seeds gave 140 sprouts, and that one pound gave 

 31,000 sprouts, and 76 seeds of 100 have sprouted: 



For impurities 8x96 =7,9 cents.
