Small Portable Boiler, 4ft. 9in. high, 2ft. 3in. diameter, ¼ inch plates, 40 lbs. pressure. The shell was rent completely off. The explosion arose from the large size of the manhole, which had no guard ring on the edge, and the lid had strained it and caused several cracks, and at last forced itself through the boiler, and the rents spread in every direction, and caused the break up of the boiler.

Marine Upright, 13ft. 3in. high, 6ft. 6in. diameter, ½ inch plates. Internal fire-box 8ft. 6in. high, 6ft. diameter at bottom, 5ft. 3in. diameter at the top, 3/8 inch plates, 50 lbs. pressure. In the sketch the shell is shown in dotted lines to allow the internal fire-box to be seen. The boiler was rent into many pieces, many of which were lost in a river, so that a satisfactory conclusion as to the cause of the explosion was impossible. The boiler was not very firmly stayed, and it is supposed that it was weakened by corrosion round the fire doors.
