It is commonly known that when radishes are left too long in the ground they become hard and woody that the soft turnipy stem of the young cabbage undergoes a similar change as the plant grows old and that the artichoke becomes tough and uneatable if left too long uncut. The same natural change goes on in the grasses which are cut for hay. In the blades and stems of the young grasses there is much sugar and starch, which, as they grow up, are gradually changed into woody or cellular fibre, (p. ...42. ) The more com- pletely the latter change is effected that is, the riper the stem of the plant becomes the less sugar and starch, both readily soluble substances, its various parts contain. And, 304 CUTTING STRAW AND GRAIN, though it has been ascertained that cellular fibre is not wholly indigestible, but that the cow, for example, can appropriate a portion of it for food as it passes through her stomach yet the reader will readily imagine that those parts of the food which dissolve most easily, are also likely, other things being equal, to be most nourishing to the animal.
