 filled it disgorges it for the purpose of eating a new ration. The size of the bluefish runs from 3 to 5 pounds, though occasionally very much larger examples are taken. As a food fish it is said to rank in the estimation of the connoisseur with pompano and Spanish mackerel. The bluefish is one of the popular fishes in all the large markets of the Atlantic coast. The flesh has a fine flavor, but, like the pompano, it does not keep well.

A comparison of the flesh of this fish with the pompano shows that it is particularly a protein food, the fat being even less abundant than the mineral matter. It, therefore, is not so well balanced a ration as the flesh of the pompano and other fish in which the fat forms a considerable portion of the edible matter.

Carp.—The carp is a fish used very largely for food purposes, but it has not the fine flavor and character of most fishes. The carp cultivated in America is known as the German carp (Cyprinus carpio).

The carp belongs to the large family of fishes known as the minnows or Cyprinidæ. This family is a large one, having about 200 genera and more than 1000 species, all of which are inhabitants of fresh water in North America and Eurasia. None of this family is highly regarded as food in the sense of flavor and aroma, except, perhaps, some of the smaller species. The nutritive value of the carp, however, is probably as great as that of any, but it is coarser and less attractive to the taste. Some of the most common species of this family are the dace, fallfish, river chub, creek chub, squaw-fish, and roach.

Catfish.—Catfish, of which there are many species, belong to the family of Siluridæ, and are among the most common fresh-water fishes found in the United States. They occur in small as well as large fresh-water streams and lakes, and it is one of the species which the American boy most delights in catching with hook and line. The catfish is most conveniently taken after night, and the smouldering fire and small boy on the bank of a stream is a frequent picture of American country life. There are more than 100 genera of the catfish family and about 1000 species. Only about one-third of the species inhabit salt water. The North American fresh-water species are confined particularly to the Atlantic coast, the Mississippi valley, and the Gulf states. There are no native species of the catfish in the fresh waters of the Pacific coast. The blue catfish, known as the Mississippi catfish, is the most prominent species (Ictalurus furcatus). It is found particularly in the Mississippi river and its large tributaries. Sometimes it grows to an immense size, individuals having been found reaching 150 pounds in weight. If the stream
