SUCCULENT VEGETABLES.

The term vegetable as applied to food in the broadest sense of the word means that class which distinguishes it from animal food. In a narrower sense, however, the term vegetable is used to denote a certain class of food which is of a succulent or juicy nature. While cereals and fruits are vegetables in the broadest sense of the word they are not in the narrow and common meaning. The term "vegetable" in this section therefore refers to those substances commonly known as vegetables upon the market and which are characterized by their high water content. On account of this abundance of liquid or juice the term succulent is applied to them. The common vegetables which are included in this class consist of lettuce, spinach, potatoes, cauliflower, beets, radishes, turnips, cabbage, green Indian corn, peas, beans, tomatoes, yams, etc. These vegetables contain in a fresh state from 70 to 95 percent of water. Many of them can be kept for a length of time without deterioration, especially the potato and beet, and for a short time cabbage, radishes, etc., if kept cool and moist. Other kinds of vegetables are not easily preserved for any length of lime except in cold storage, such as lettuce, peas, beans, tomatoes, etc. If the potato and other starchy tubers are kept out of account these vegetables do not have a very high nutritive value, as will be seen by the analysis which follows. They have, however, an important part in the ration because of their palatability and the effect which they have upon the general activity of the alimentary canal. For instance, there is very little nourishment obtained in eating a turnip which perhaps is 95 percent water,—yet its palatability, its condimental character, and its general salutary effect upon digestion is such as to make it worth while to pay even a high price in proportion to its nutriment. For this reason, as well as for their nutritive value, the use of succulent vegetables is to be very highly commended.

In general, as has been said, these vegetables are eaten in a fresh state or after being kept for a considerable time in cold storage or otherwise. The potato, for instance, can be kept by properly covering it in the earth or in bins through the winter. Cabbages are also kept in the same way and many
