Oysters are plentiful along the Pacific coast of the United States and also in European coast-waters, but they are inferior in size and quality. The use of refrigerator-cars and vessels has extended the trade to the extent that fresh oysters are shipped to points 2,000 miles inland; they are also exported to Europe. Baltimore is the chief oyster-market.
The consumption of the lobster has been so great that the catch of the New England coast has decreased about one-half in the past fifty years, and the United States is now an importer. Most of the import, amounting to about one million dollars yearly, comes from Canada. The so-called lobsters of the Pacific coast of the United States are not lobsters, but crayfish.
Fish Hatcheries.—The demand for fish has grown so great in past years that in many countries the waters, especially the lakes and rivers, are restocked. The eggs are hatched and the young fry are fed until they are large enough to take care of themselves. The chief hatchery and laboratory of the United States Fish Commission is at Woods Holl, Mass. As many as 860,000,000 eggs, small fry, and adult fish have been distributed in a single year. The State of New York has also a similar department for restocking its waters.
Sponge.—This substance is practically the skeleton of a low order of animal, growing at the bottom of the sea. The sponge is cut from the place of attachment, and the gelatinous matter is washed away after putrefaction. The chief sponge-fisheries are in the neighborhood of Florida and the Bahama Islands.
Seal.—The fur-seal is an amphibian, found only in cold waters. A few pelts are obtained along the Greenland coast, but the chief sealing-grounds of the world have been at the Pribilof Islands, in Bering Sea. The pelts of the young males only are taken. The rookeries of the Pribilof Islands have been so nearly exhausted, that the killing season has been suspended for a term of years. Much illicit seal-catching is still going on, however.
The skins are taken to London, via San Francisco, where the fur is dyed a rich brown color; London is the chief market for dyed pelts; San Francisco for raw pelts; and New York, Paris, and St. Petersburg for garments. The pelts of the sea-otter are obtained mainly in the North Pacific Ocean.
Other Furs.—The furs employed in the finest garments are in part the pelts of land animals living in polar regions. The sable, stone-marten, otter, beaver, and red fox are the most valuable. The Persian lamb, however, is not a polar animal. The Russian Empire and Canada are the chief sources of supply. The Hudson Bay Company, with head-quarters at Fort Garry, near Winnipeg, controls most of the fur-trade of North America; the Russian furs are marketed mainly at Lower Novgorod. Leipzig, Germany, is also an important fur-market.
Enormous quantities of rabbit-skins from Australia and nutria from Argentina are imported into the United States and Europe for the manufacture of the felt of which hats are made. The amount of this substance may be realized when one considers that not far from two hundred million people in the two countries wear felt hats.
