CATFISH. Two entirely different fish--one found in salt-water and the other in lakes and rivers--are known as "catfish." The flesh of the salt-water fish, which occasionally attains a weight of sixty pounds and is called the "Hogfish" in some parts, is very good in flavor, but the catch is nearly all cured, very little being marketed fresh. The river variety is smaller and not particularly choice in flavor, but properly prepared, after the removal of its coarse brown skin, it is found quite as pleasing to the palate as many more highly rated fish. Catfish dinners are much esteemed along the Schuylkill River at Philadelphia.
