Some of the big harvesters that cut and thresh the wheat are drawn by a traction-engine instead of horses. In running a fifty-horse-power engine high-priced coal had to be burnt but now the coal grates are replaced by petroleum burners, and crude coal-oil is the cheap fuel. This does not make sparks to set the fields on fire like burning coal or straw and so is safer to use. On large ranches wheat can be grown for less than a cent a pound, while it has brought two cents or double the money when sold. But there are not always good crops, as the grain needs plenty of moisture in the spring when rains are uncertain. The wheat crop of the state has fallen off of late to less than half the yield of earlier years, but the deep, rich valley soil still grows grain enough to feed hungry people in Europe, Asia, and Africa, as well as in our own Union. Great quantities are taken in large four-masted ships to Liverpool, England, and there made into American flour. Our own flour-mills turn out thousands of barrels of flour, and this travels far, too. The first thing picked up in Manila after Admiral Dewey's victory was a flour sack with a California mill mark. It would need a long, long story to tell how far from home and into what strange places the yellow kernels of California wheat sometimes travel, or to picture the odd people who depend upon us for food. ORCHARD, FARM, AND VINEYARD Long ago the Mission Fathers taught the Indians to plant and to take care of vines and fruit-trees. They built water-works to bring life to the thirsty trees in the dry summers, and to grow oranges, limes, and figs, as well as peaches, apricots, and apples. They trained grape-vines over arbors and trellises round the Mission buildings, and from the small, black grapes made wine. Olive trees and date-palms did well at the southern settlements. But most of these orchards died when the Mission Fathers were no longer allowed to make the Indians work for the church property, though a few old palms and olive trees are still standing. During Mexican days each ranch owner raised enough grain or corn and beans for his own family but planted no fruit, or but little, while the Americans who came to seek gold thought farming a slow way of making a living. People soon found out, however, that our fine climate and rich soil made good crops almost certain, and there was such demand for fruit and farm products that more and more acres were cultivated each year. Our leading industry now is farming and fruit-growing, and California's delicious fresh or cured fruit is sent all over the world. Large amounts of barley and hops are shipped from here to Europe, and our state produces almost all the Lima beans used in the country.
