Sugar Beets and Sugar Cane 71 close at hand, and the great sugar-cane regions are far away. The summer traveler in northern Europe long remembers the great ex- panses of beet fields, and the peasant women and children on their knees pulling the weeds that would smother the young plants. The climate for sugar cane. The coolest places where the sugar cane grows are our southern states, from eastern Texas to South Carolina, as appears in Figure 52. There the frost kills the cane each winter, but the difficulty is overcome by planting new canes every year early in the spring, after the last frost of the winter, and harvesting them late in the fall, before the first frost of the next win- ter. To follow this method successfully requires at least eight months without frost. Nearér to the equator, in such places as the great sugar-cane islands of the West Indies, Java, Hawaii, and Mau- ritius, the cane is allowed to grow from three to ten years before new plantings are made, and a heavy crop is cut from the plantation every year. In the islands just mentioned and in sugar-cane regions of less importance, such as India, Egypt, Brazil, northern Argentina, and the Philippines, a high, uniform temperature prevails and the rainfall is abundant. Under these conditions not only is the cane full of sap, but the sap carries a high percentage of sugar. Sometimes as many as eight tons of sugar are made from the cane cut annually on one acre of land. Sugar cane on the Cuban plantations.

Fic. 54. Sugar cane grows only in regions that some time in the year have an average tempera- ture of 80 degrees; that is, sugar cane is almost a purely tropical crop. (Compare with Figures 17 and 18, pages 30, 31.) India, Cuba, and Java produce the bulk of the world’s supply. There are vast undeveloped regions in Africa and in Brazil that may sometime be used for sugar cane. Northwestern Europe is the greatest producer of beet sugar. About half the world’s supply of sugar comes from beets and half from sugar cane
