The oysters are heaped up in great piles on the deck of the boat. Sacks and barrels are filled with them, and many car loads are shipped daily from the cities near the fishing grounds. Chesapeake Bay is the center of the oyster industry in our country. Find it. There are oyster beds, however, all along both the Atlantic and the Pacific coasts. Great quantities of oysters are canned near where they are caught. Getting them out of their shells is not an easy matter. For this purpose a knife is used. This work is called in the South "shucking oysters." Canning oysters is an important industry in the city of Baltimore. Have you ever seen cans of oysters that came from there? A RICE FIELD When you do not feel quite satisfied with your breakfast, dinner, or supper, and think that there should be a greater variety of food on the table, just come with me and we will visit some of the boys and girls of far-away China. What do you suppose _their_ chief article of food is? Rice. Rice in the morning, rice at noon, and rice at night. Rice from the beginning to the end of the year. In the poorer families a bit of dried fish and some vegetables are usually eaten with it. Those who can afford such things have bits of preserved ginger, mushrooms, and barley cakes with the rice. Of course the rich people have other things to eat, but most of the people of China are poor. In the fertile portions of China the people live very close together. Gardens take the place of farms. Workmen often receive no more than ten cents a day. On this account they cannot afford the variety of food that we have, but must be content with whatever is cheap and nourishing for their labor. If the rice crop were to fail, the Chinese would suffer. You will see how important this food is to them, when I tell you that they are forbidden by law to sell rice to other countries. Perhaps you are wondering where the rice that we use in this country comes from. Rice is grown in great quantities in Japan, Corea, Indo-China, Ceylon, India, the Philippines, the Hawaiian Islands, and in our Gulf states. Rice is the chief food of one half the people of the world. Although we raise large quantities, we produce only about one half of what we use. It is a kind of grain which will not thrive on the fertile Western prairies where corn, oats, and wheat grow. It needs a warm climate and a great deal of water. For this reason the rice fields are found on the marshy lands near the coast, and by the banks of rivers, where they can be easily flooded. Some rice is raised on the uplands, but not so successfully as on the lowlands. Canals are dug from the streams through the farms, and from these smaller ditches branch off so as to reach all parts. They are so arranged that the farmer can turn the water on or off whenever he wishes. On some of the farms, wells furnish the water to the canals.
