Alaska is one of the most important fishing regions of the world. For this entire Territory, the United States paid Russia $7,200,000 and many thought that the money was practically thrown away, since it apparently bought for us nothing but barren, ice-bound shores. But since it became a part of the United States, Alaska has yielded fishery products alone amounting in value to $158,000,000--twenty-two and a half times the price paid. Of this, $49,000,000 came from the fur seal fishery, $86,000,000 from salmon and $23,000,000 from other fish. About $1,500,000 worth of sponges are now taken from Florida waters each year. Naturally the failure of the industry would be a serious loss to the state. But the natural sponge beds are being rapidly exhausted, and the Bureau of Fisheries is convinced that the continuation of the sponge fisheries must depend on artificial planting. Sponges can be produced from cuttings at a cost much less than that of taking them from the natural beds. Rhode Island has been successful in cultivating soft-shell clams and in increasing the area of its clam beds. The Mississippi and its branches are subject to great floods in the early spring and occasionally in summer. After these floods millions of fishes are left in small pools some distance back from the river. These pools gradually dry up; the larger fishes are caught and the smaller ones die. The state and National Fish Commissions are now collecting these fishes in large numbers, and using them to stock ponds and rivers in other parts of the country. They are used to supply many parts of the West and South and there is much greater demand for them than the Commissions can meet. Not that there is a lack of fish, for millions are left to waste because the Commissions can not distribute them rapidly enough to save them. If large storage ponds could be established to collect and keep the fish during the flood season, so that all the time might be spent in collecting fish during the overflow, and they could be sent out later, the amount of fish saved would be increased many fold. The fish thus saved are being made to serve another useful purpose. Pearl buttons are made from the shells of mussels or fresh-water clams. This business, which is now worth $5,000,000, can not last many years unless some means of increasing the supply of mussels can be devised. Now these men, who are always studying new plans, have thought of a wonderful way in which to let the fish help in carrying on this work. They obtain the mussel eggs, and when they are hatched place them in the pools with the fish from the overflowed lands. The tiny mussel larvae attach themselves to the fish and are carried to the rivers and ponds with the fish. Soon they are ready to drop to the bottom and find food for themselves.
