We have now considered six groups of topics connected with the growth and development of our country. We have looked into the houses of the Indians and of the settlers in the colonial times, and into the larger and more elaborate homes of to-day. We have considered improved means of heating and better methods of lighting. We have noticed improvements in machinery for planting, cultivating, and harvesting the products of the soil. We have seen the great advance that has been made in the manufacture of our clothing, through improved cotton and woolen machinery and the sewing machine. We have traveled by land and by water, at home and abroad, on foot, on horseback, in stagecoaches, by canals, steamboats, and railroads. Finally we have read and thought and studied about language, the printing press, our postal system, the telegraph and the telephone. We have seen our country when it was wholly east of the Mississippi River, whereas now it is extended even to the great western ocean. A century ago our territory embraced about eight hundred thousand square miles; now it is nearly five times as great, with large areas of recently acquired Spanish islands to be added to that. The population of the United States in 1790 was less than four millions; a hundred years later it was sixty-three millions. It is now probably between seventy and seventy-five millions. Our exports then were about fifty million dollars in value; this year they are more than one thousand millions. A century since, we imported into this country goods to the value of about seventy million dollars. This was largely in excess of our exports. To-day our exports are of far greater value than our imports. At the beginning of our national government we were almost altogether engaged in the pursuits of agriculture. Now our people are largely massed in cities and large towns, while our mechanical and manufacturing interests are of immense proportions. A hundred years ago the people speaking the seven principal languages of Europe numbered about one hundred and fifty millions. To-day they number about four hundred millions. The present number is therefore almost three times that of a century ago. At that time the English-speaking people ranked fifth among the seven, and numbered but twenty millions. To-day they lead the list, and number one hundred and twenty millions; there are six times as many people to-day using the English language as there were a century ago. The inhabitants of our country outnumber all other English-speaking people in the whole world.
