Excerpt from A System of Iron Railroad Bridges for JapanThere are probably 300 miles of iron bridges in the country now, and perhaps in the neighborhood of 700 miles of wooden bridges. I am speaking now of railway bridges. The construction of road bridges is quite a separate and distinct industry. It is the price of iron that regulates the cost of a bridge, the cost of labor has very little to do with it.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
