BEET-ROOT SUGAR AND 



cows B, fed chiefly on pulp, fell from 3i T 4 oo- to 21-^7 

 pounds. 



The following is a tabular statement of the result 

 for the first four weeks, and of the yield of cows A 

 for the last four weeks : 



The daily yield of milk from cows A, when fed 

 upon leaves, rose from 20 pounds to 23.75 m the fifth 

 week, 26.87 * n tne sixth, 28.44 ' m tne seventh, and 

 29.53 in the eighth. 



The milk produced by cows, 



A in ist and 2d week, on pulp, averaged 2.8% butter. 



B " " on leaves, " 3.7 " 



A in 3d and 4th week, on pulp, 3.

The experiment ended April 3d. 



The conclusions are, that salted leaves can be pre- 

 served ; that their use, in conjunction with pulp, in- 

 creases the flow of milk and yield of butter ; and that 

 they are preferable to pulp alone. 



The weight of leaves is about twenty per cent, of 

 the weight of the roots ; therefore a factory that con- 

 sumes 24,000 tons of beets annually furnishes 4,800
