SUGAR 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. (Agr. Sci., Vol. IV, p. 326.) 
GRASSES. 
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.)
