within the more favorable temperate zone, the greater part of the North American triangle is within the temperate zone. With regard to location for world trade the northern continent again has the advantage: the ports of South America face a relatively empty ocean on the west and the little-developed continent of Africa on the east; the ports of North America, in addition to being more numerous and more suitable for commerce than those of the s

ans, into the great Mississippi basin, and westward to the Pacific Ocean. Accompanying the increase and westward spread of the population has come a greater variety of racial types. Although our population was varied in colonial times, the great majority of the settlers were from the British Isles and northwestern Europe. In the latter part of the nineteenth century immigra

Industrial and financial disturbances during the period of the World War make later estimates hazardous, nevertheless it is interesting to note that in 1921 the wealth of the United States was estimated as being between $350,000,000,000 and $400,00

million are engaged in agriculture and allied industries, while more than eleven million are busy in manufacturing pursuits. Almost four million are found in some form of trade, and another four million are employed in domestic and personal service. Transportation, clerical work, and professional callings utilize the services of several a

hose of any other country. Iron is found in most of the states in the Union, the high-grade deposits of the Lake Superior area being of special importance. We produce more than half of the world's supply of copper, which, after coal and iron, is the most important industrial mineral. Our supply of petroleum and natural gas is large, and in

world in the value of farm crops grown. Our production of wheat, corn, oats, barley, rye, and dairy products totals an enormous figure. The steady enclosure of lands formerly used for grazing stock is restricting our production of food animals, but we are still important as a producer of meats. Most of the world's tob

s developed, transportation was fostered, and larger and larger markets were supplied with the products of American manufacturers. Particularly since the Civil War has the importance of our manufactures increased. This increase has been due chiefly to the large scale production of foodstuf
