that the falling off in the milk supply due to lactation is 

 measured by the difference between the quantity of milk 

 yielded by the cows, the fat contents, etc., in the fourth and

In summing up the conclusions to be drawn from this 

 experiment, Herren Ramm and Momsen say that it is clear 

 that the effects due to feeding with molasses are not due to 

 the sugar only, but that the other constituents are also 

 efficacious, and the advantages of molasses, which had 

 already been demonstrated at Poppelsdorf as well as else- 

 where, must be attributed to these other constituents. 

 Among these it would appear probable that it is the nitro- 

 genous matter that is the most useful, although the remainder 

 may also be of importance. 



It may perhaps be mentioned that the molasses and sugar 

 used in these experiments were obtained from beets. 



Manuring of Meadow Hay. 



In the grass districts of Yorkshire it is the usual prac- 

 tice to give meadows either an annual dressing of dung or 

 to give such a dressing once in every two years, and in 

 the latter case artificial manures are sometimes applied 

 in the intervening year. In 1899 an experimental scheme
