"Tell me something about the railways," exclaims Gunnar, who wants to go out west at the first favourable opportunity.
"Yes, I can give you information about them, for I have been working on several lines. As far back as 1840 the United States had 2800 miles of railway, and twenty years later 30,000 miles. Now it has nearly two hundred and forty thousand miles of rails, a strip which would reach to the moon or ten times round the equator. The United States have more railways than all Europe, though the population is only a fifth that of Europe; but the area is about the same."
"How do you explain this rapid development of railway enterprise?"
"Well, the fact is that at first the aim was to fill up the gaps between the waterways. Rivers were relied on as long as possible, and the first railways were built in districts where there were no large rivers. Then in course of time various lines converged together, new railways were constructed, and now the forty-nine States are covered with a connected network of lines. Moreover, the country roads are so bad that they must be supplemented by railways."
"A large number of bridges must be necessary across all the large rivers?"
"Yes, certainly. The Americans are adepts in bridge-building, and the railway bridges over the Mississippi and Missouri and other rivers are masterpieces of the boldest art. Where lines cross deeply eroded valleys, bridges of timber were formerly built, like sky-scraping parapets with rails laid along the top; but such bridges are now fast disappearing and iron bridges are built, and the trains run at full speed over elegant erections which from a distance look just like a spider's web. Just look to your left. There you have one of the world's strongest bridges, the suspension bridge between New York and Brooklyn. It is of colossal dimensions, and yet it looks so fine and delicate as it hangs between its two mighty piers. You see that vessels with the tallest masts can pass clear below, for it is poised 135 feet above high water. The length is nearly a mile and a quarter. It is wonderful that men have been able to stretch this huge span of iron above the water. Wait a little and you will see a kind of aerial railway."
Then the Stockholm man takes his new friend to a station to travel on the elevated railway through New York. Gunnar's astonishment is beyond bounds as he rushes along on a framework, supported by innumerable iron pillars, over streets and squares, and sees the seething crowd moving in carriages and on foot below his feet.
"Here is the Central Park. Is it not delightful with its leafy trees and cool pools? In summer it is burning hot in the town, and it is refreshing to rest an hour or two in the shade of the trees. The winters are equally cold, and raw, biting winds blow from the east coast. Here is Fifth Avenue, the finest street of New York. In the row of palaces you see here live millionaires, railway kings, steel kings, petroleum kings, corn kings, a whole crop of kings. But I would rather we went to look at the rows of houses facing the Hudson River."
"New York lies, then, on the Hudson River?"
