There had been leaks in the tubes and four had beenplugged. There was a crack in the upper head near thecenter which extended between three tubes. From thiscrack steam escaped, and the water had settled upon thesurrounding surface of the tube-head and the result was to reduce the five-sixteenths plate to lessthan a quarter of an inch in thickness, and the tube-endsto the thickness of writing paper. The lower tube-endshad suffered still more from leaks and were as thin as paperand afforded no adequate support to the head. Thepressure consequently forced the lower head down, open-ing fifty or more holes, two inches diameter, from whichthe fluid contents of the boiler issued at a high velocity,and the whole boiler became a great rocket weighingabout two thousand pounds. THE RESULTS OE EXPLOSIONS. I5I One life was destroyed by this explosion and a con-siderable amount of property. An explosion which occurred at Jersey City, N. J.,some years ag
