One of three. Plain Cylinder, 27ft. long, 5ft. diameter, 3/8 inch plates, 35 lbs. pressure. The boiler was much torn up, and all the fragments thrown to the front of their original position. The cause of the explosion was that the boiler was very old and much deteriorated, so that it was unable to bear the ordinary pressure. The longitudinal arrangement of the plates, and the entrance of the feed directly on the bottom, no doubt contributed to the weakness.
