ing, and thus removes from the agriculturist a portion of his labor which is not of the most agreeable kind.
Composition of Yams.—The composition of yams does not differ to any notable extent from that of the sweet potato.
Other Uses of the Yam and Sweet Potato.—In addition to the use of the yam and sweet potato for human food, reference has already been made to their value as food for domesticated animals. These bodies are particularly relished by hogs and cattle. The feeding of sweet potatoes or yams to milk cows insures a healthy condition of the body, and also imparts to the milk, cream, and butter the distinct amber tint which is regarded as a mark of excellence. Thus even in the winter months the butter which is made from milk produced in this way will have the light amber tint, which should distinguish it from the highly tinted artificially colored product which does so much to bring good butter into bad repute. Both sweet potatoes and yams are capable of yielding abundant supplies of distilled spirits. It is probable that under the new law which permits the use of denatured alcohol free of taxation in the arts an abundant supply of this product can be secured from the sweet potato and the yam. There are millions of acres of cheap land of a sandy character in the South Atlantic and Gulf states where potatoes and yams can be successfully grown under scientific principles of agriculture. If not needed for food purposes as above mentioned, the residue can be very profitably devoted to the manufacture of industrial alcohol.
CANNED VEGETABLES.
It probably will excite no opposition to state that if fresh, succulent vegetables can be placed upon the table of the consumer they are to be preferred to the same kind of vegetables preserved in any manner. There are many circumstances, however, which render it difficult, if not impossible, to secure a regular supply of fresh, succulent vegetables upon the consumer's table. Those who possess abundant wealth may have a proper supply of vegetables at all seasons of the year without resorting to any preserving process other than the refrigeration incident to transportation. But the great majority of consumers must of necessity adapt themselves to the conditions of the market and the proximity of supply. Succulent vegetables properly harvested and refrigerated may be sent long distances and over a considerable period of time, and reach the consumer in practically the same state of freshness and palatability as when first harvested. Owing to the exigencies of intermediary supply and the cost of transportation the great industry of keeping succulent vegetables by sterilization has been founded. Commonly vegetables prepared in this way are known as "canned" vegetables in this country and "tinned" in England. By availing himself of this process the consumer, even of moderate
