sixth place among our great cities. This 

 is due to the rapid development of the 

 iron industry, for Cleveland is the lead- 

 ing place where the iron ore from Lake 

 Superior meets the coke from the Pitts- 

 burg region. 



Baltimore showed a slow growth and 

 was forced out of sixth place by Cleve- 

 land. Pittsburg has not grown as rapidly 

 as was expected of our leading iron cen- 

 ter. The chief growth has' occurred in 

 the boroughs surrounding Pittsburg, in 

 Allegheny County, which nearly doubled 

 in population in the decade. If Pitts- 

 burg were to extend her corporate limits 

 to include these boroughs, she would 

 contain nearly three-quarters of a million 

 people, and would be the fourth city of 

 the country in population. 



Detroit has grown at a tremendous 

 rate, and has come up from thirteenth 

 place to ninth. This is owing mainly to 

 the development of the automobile in- 

 dustry, of which it is perhaps the largest 

 center. The growth of Buffalo is at first 

 sight disappointing, but the towns be- 



tween it and Niagara Falls, its suburbs, 

 have grown enormously, owing to the 

 development of power from Niagara 

 Falls. 



The case of San Francisco is a marvel- 

 ous one. Destroyed by earthquake and 

 fire only four years ago, it has rebuilt 

 itself, and has not only held its population 

 of ten years ago, but increased it between 

 a fourth and a fifth, while the cities 

 across the bay have grown at almost 

 fabulous rates. 



Indeed, the cities of the west coast 

 have grown tremendously. Los Angeles 

 has more than trebled its numbers ; Seat- 

 tle and Spokane have nearly trebled 

 theirs, and Portland has much more than 

 doubled hers. 



Of all the cities of the country, how- 

 ever, Birmingham, Alabama, has made 

 the most startling strides. In 1910 it 

 contained nearly three and one-half times 

 as many people as in 1900. Its progress 

 is due, as is well known, to its iron manu- 

 factures. Atlanta, Georgia, another city 

 of the South, has had a great growth.
