I.—THE BROOKLYN SUSPENSION BRIDGE.  

HEN two large cities stand opposite to one another on the banks of a river, it is not likely they can do very well without a bridge to connect them. Yet the citizens of New York and Brooklyn were obliged to manage as best they could for a good many years before they had their bridge. There were many difficulties in the way. For one thing, the river is very broad; for another, the tall-masted ships ply up and down so frequently that it would never do to build anything which would obstruct their passage; and to overcome these difficulties would mean the expenditure of a vast sum of money. But the folk who earned their daily bread in New York and lived in Brooklyn grew thoroughly tired of spending chilly hours in foggy weather on the river-side piers, waiting for the ferry-boat to come and take them across, and at last they began an agitation which resulted in the Brooklyn Bridge.

The engineer who made the first design was Mr. John A. Raebling; but he did not live to see it carried into effect; for one summer day in 1869, when selecting the spot at which the great work should be begun, he met with an accident which caused his death a few days later. His son, Mr. Washington Raebling, then took the lead. Plans were carefully drawn and submitted to the Government, who, after much consideration, ordered that the bridge should be five feet higher and five feet wider. This apparently slight change added about 172,800l. to the cost of building, for little changes in big things mean more than big changes in little ones. The original cost was to be 10,800,000 dollars, or about 2,160,000l.; but in the end it amounted to nearly 3,100,000l.

Before we talk of the trouble and labour, let us look for a moment at the great things the engineers have accomplished.

The Brooklyn bridge is five thousand eight hundred and eighty-nine feet long and eighty-five feet wide. The huge cables that support it stretch like the strands of a monster spider-web from the tops of two towers, each two hundred and seventy-six feet high and standing one thousand five hundred and ninety-five feet apart. The above is the length of the central span; the two other spans, from the land to the towers, are each nine hundred and thirty feet long in addition. The roadway, one hundred and thirty-five feet above the river, is divided into five parts. The two outside ones are for vehicles, the middle one for foot passengers, and the remaining two for cable trams. The footway is eight feet higher than the others, so that an uninterrupted view is gained from it. The four cables supporting this heavy structure are anchored at both ends in blocks of masonry weighing sixty thousand tons each; so that there is little fear of their being dragged from their moorings. The bridge was opened amid a blaze of fireworks on May 24th, 1883.

On May 7th, 1870, the tower on the riverside at Brooklyn was begun, and completed just five years later; its companion on the opposite side was a year behind it. The foundations of these great towers lie in solid rock seventy-eight feet below the high-tide line on the New York side, and only a little less on the Brooklyn side....
