a thin flat knife under the back end of the right valve, and push forward until it cuts the strong muscle which holds the shells together. As soon as this is done, the right valve may be raised and separated from the left. _To Clean Oysters._ Put oysters in a strainer placed over a bowl. Pour over oysters cold water, allowing one-half cup water to each quart oysters. Carefully pick over oysters, taking each one separately in the fingers, to remove any particles of shell which adhere to tough muscle. =Clams=, among bivalve mollusks, rank in value next to oysters. They are found just below the surface of sand and mud, above low-water mark, and are easily dug with shovel or rake. Clams have hard or soft shells. Soft-shell clams are dear to the New Englander. From New York to Florida are found hard-shelled clams (quahaugs). _Small quahaugs_ are called _Little Neck Clams_ and take the place of Blue Points at dinner, when Blue Points are out of season. =Scallops= are bivalve mollusks, the best being found in Long Island Sound and Narragansett Bay. The central muscle forms the edible portion, and is the only part sent to market. Scallops are in season from October first to April first. II. Crustaceans =Lobsters= belong to the highest order of Crustaceans, live exclusively in sea-water, generally near rocky coasts, and are caught in pots set on gravelly bottoms. The largest and best species are found in Atlantic waters from Maine to New Jersey, being most abundant on Maine and Massachusetts coasts. Lobsters have been found weighing from sixteen to twenty-five pounds, but such have been exterminated from our coast. The average weight is two pounds, and the length from ten to fifteen inches. Lobsters are largest and most abundant from June to September, but are obtainable all the year. When taken from the water, shells are of mottled dark green color, except when found on sandy bottoms, when they are quite red. Lobsters are generally boiled, causing the shell to turn red. A lobster consists of body, tail, two large claws, and
