CHAPTER XIII
UNDER THE RIVER
The tunnel under the Hudson River was begun several decades ago. It was started from the New York side, a little south of Christopher Street, and continued out under the bed of the river for some distance. Then the company failed and they built a brick wall, twenty-four feet thick, at the end of the tube they had dug. It remained in that condition for many years, until a new company was formed. This concern took up the work where the others left off.
There were two tubes, each circular, and about twenty-four feet in diameter, dug under the river. They were separated by a wall of earth, and each tube was lined with heavy cast iron. In cutting the tube a big thing like an exaggerated apple corer was pushed through the earth sixty feet below the surface of the river bed by hydraulic force. To prevent the water from rushing in, the shield was kept filled with compressed air at a heavy pressure.
Up to within a few days this compressed air had been used in the tunnel, but when the reporters started through the tunnel was near enough completion to render it unnecessary. The heavy cast iron lining was all in place, except where the brick wall was, and it only remained to cut through the masonry, establish communication from one end to the other, fit a few pieces of cast iron into place, and the tunnel would be established. The cutting through of the wall was the event of great importance, and really marked the completion of the first stage of the work. Hence every reporter felt the need of getting a good story about it.
“We’ll try to beat ’em,” whispered Mr. Newton to Larry as the party started forward.
The tunnel was cut in a slanting or downward direction at first. It began several hundred feet back from the edge of the river and, when it was actually below the bed of the stream it was level.
It was quite dark in the big tube, save here and there where electric lights gleamed. Most of the party walked, but there were small cars, hauled by a cable, for the use of the directors and officials of the construction company.
Through the tube they went. In spite of the heavy lining, sustaining thousands of pounds of pressure, some water leaked in. It splashed down in big drops, and felt like rain. Once a drop fell on Larry’s lips, and it tasted salty, just as the lower Hudson River does. Then he began to realize that he was in a queer place, under the bed of one of the largest rivers in the United States. It hardly seemed possible that he was walking under the historic stream that Henry Hudson, in the Half Moon, discovered so many years ago.
As the party progressed, the president explained the workings of the machinery, and stated that when the concrete lining had been placed over the iron, there would be no leakage.
