FACTS and figures concerning the extent to which seaweed in the form of a dried meal is incorporated in balanced rations for cattle, sheep, pigs and poultry are surprising and confirm the value placed upon seaweeds by the people of the Far East. Those who have lived in China know the value placed upon seaweeds. The Chinese import the dried product from the Pacific coast and use it daily as an important part of their diet ; it forms one of the chief sources of supply of mineral salts. In the Hawaiian Islands more than seventy species of seaweed are reputed to have food value, but so far as is known no one has yet attempted to classify the world's Algæ, or even those of any country, according to their edible qualities. These appear to vary widely as to plants and in the parts of individual plants.
