364. The States.--As it was with the cities so it was with the states--the North had grown beyond the South. In 1790 Virginia had as many inhabitants as the states of New York and Pennsylvania put together. In 1860 Virginia had only about one-quarter as many inhabitants as these two states. Indeed, in 1860 New York had nearly four million inhabitants, or nearly as many inhabitants as the whole United States in 1791 (p. 156). But the growth of the states of the Northwest had been even more remarkable. Ohio now had a million more people than Virginia and stood third in population among the states of the Union. Illinois was the fourth state and Indiana the sixth. Even more interesting are the facts brought out by a study of the map showing the density of population or the number of people to the square mile in the several states. It appears that in 1860 Ohio, Pennsylvania, Maryland, Delaware, New Jersey, New York, Connecticut, Rhode Island, and Massachusetts each had over forty-five inhabitants to the square mile, while not a single Southern state had as many as forty-five inhabitants to the square mile. This shows us at once that although the Southern states were larger in extent than the Northern states, they were much less powerful.

Life in them was just about the same as in the smaller places. Now, however, there was a great difference. In the first place the city could afford to have a great many things the smaller town could not pay for. In the second place it must have certain things or its people would die of disease or be killed as they walked the streets. For these reasons the streets of the Northern cities were paved and lighted and were guarded by policemen. Then, too, great sewers carried away the refuse of the city, and enormous iron pipes brought fresh water to every one within its limits. Horse-cars and omnibuses carried its inhabitants from one part of the city to another, and the railroads brought them food from the surrounding country.
