But I sez, with dignity, "Perhaps I know more about some things than you do, Josiah. There may be, by this time, one or two more inhabitants."

Sez Mr. Bolster, "A growth of about 200 in one hundred years! Chicago is about half as old, and has one million eight hundred thousand population. In ten years the population has increased 108 per cent, and property has increased in the same time 656 per cent, the greatest growth in the world."

He regarded Jonesville as he would a fly in dog days. He went right by it.

"As I was saying, we say nothing about Chicago but what we can prove. Look on the map and you will see for yourself that Chicago is right in the centre of the habitable portion of North America. Put your thumb down on Chicago, and then sweep round it in an even circle with your middle finger, and you will see that it takes in with that sweep all the settled portion of North America."

"Yes," sez Josiah, with a air as if he had proved it with his thumb and finger, time and agin, but he hadn't no such thing.

Sez Mr. Bolster, "We say nothing about our City that we can't prove. As Chicago is in the very centre of productive North America, so it is the centre of population of the United States.

"It is the centre of the raw materials for manufactures, cotton, wool, metals, coal, gas, oil fields, all sorts of food. And as it is the centre of supply, so it is of distribution—60 railroads and branches bring freight and carry out manufactured products to every part of the country—to say nothing of the great number of lines of water transportations—connecting with all parts of the world. Why, last year Chicago had 50 per cent more arrivals and clearances than New York. It is the greatest shipping place in America. And," sez Mr. Bolster, "not only can we prove that Chicago is the centre of the world for manufactures, but it is the healthiest place to live in."

And then agin I spoke out, and, sez I, "I always hearn that it was built on low, swampy ground."

"Yes," sez Mr. Bolster cheerfully, "that is the reason why it is healthy. The ground was originally low and wet, and so it was elevated, filled in. Why, just before the great fire we lifted up all the houses, in the best part of the city, on jack-screws for eight feet, and filled the ground under them. The idea of lifting up a whole city eight feet and making new ground under it! There never was such an undertaking before since the world began.
