SUGAB BEETS. 



Durin has shown that the sugar beet loses the sugar in the root by 

 its consumption in forming stalks and leaves as well as seeds. The 

 roots die when all the sugar is used up, from which I infer that the 

 best time for gathering the beets must be at that period of ripeness 

 in which the formation of leaves ceases, and possibly this formation 

 of leaf and loss of sugar can be checked artificially by cutting the 

 young leaves. (Agi*. Sci., Vol. IV, p. 326.) 



6BASSES. 



The changes in the chemical composition of grass and in the 

 nutritious quality of the dried hay have been determined by E. F. 

 Ladd (Agr. Sci., Vol. I, p. 221) by experiments on timothy {Phleum 

 'pratense)^ who concludes as follows: 



(1) The amount of water in timothy diminishes rapidly. 



(2) There was a large increase in crude fiber in late-cut timothy 

 over that cut at the period of full bloom. 



(3) As the grass approached maturity there was a considerable 

 diminution in the percentage of sugar and an increase of the starch. 



(4) After the period of full bloom the proportion of albuminoids 



to the other organic constituents diminished.

(8) Finally, from a chemical point of view, it seems preferable to 

 cut timothy for feeding at the period of full bloom, rather than after 

 the seeds have formed. (Agr. Sci., Vol. I, p. 223.)
