One of six. Plain Cylinder, 36ft. long, 6ft. diameter, 3/8 inch plates, 50 lbs. pressure. Although the boiler was not an old one, it had been much repaired at the seams with strap plates. It was said that the water was very bad, and deposited much mud, which allowed the seams to get overheated and injured. The seam which rent was an original one, and no doubt was ripped as the others had been before repair, and that this rip extended from hole to hole until a rupture at the ordinary pressure was the result. _No. 33. Preston. August 4th. 1 killed._ Locomotive. In shunting the engine was dragged under a bridge that was not intended for locomotives to pass, and the dome was knocked off. _No. 34. London. (Fig. 24.) August 11th. 3 killed._ [Illustration: _Fig. 24._] Marine, 8ft. long, 5ft. 6in. diameter, 3/8 inch plates, 80 lbs. pressure. The flat front end gave way at the angle iron all round, allowing the front with tubes attached, and the shell to be thrown in opposite directions. The front being flat was very weak, and depended for its strength on gusset stays and small bolts connecting the back of the combustion chamber and the round end of the shell. These stays were very defective and insufficient, and the angle iron was bad and not welded into one ring, and the boiler was therefore unfit to bear the ordinary pressure, and gave way at the weakest place. _No. 35. Cornwall. (Fig. 25.) August 16th. none injured._ [Illustration: _Fig. 25._] One tube Cornish, 32ft. long, 6ft. 6in. diameter. Tube 4ft. diameter, 7/16 inch plates, 40 to 50 lbs. pressure. There was no steam gauge. The tube collapsed from end to end, both ends being torn, but the boiler was not moved from its seat. The fusible plug was uninjured. The cause of the explosion was the weakness of the large tube. See No. 57. _No. 36. Leicester. (Fig. 26.) September 1st. 1 injured._ [Illustration: _Fig. 26._] Upright, 5ft. 6in. high, 4ft. diameter, 7/16 inch plates, 40 lbs. pressure. The top of the boiler was blown out. The rent commenced in the manhole, which was unguarded by a ring, and cracks two inches long had existed before explosion. See Nos. 12 and 18. _No. 37. Preston. (Fig. 27.) September 3rd. 1 killed, 1 injured._ [Illustration: _Fig. 27._] One of two. Two tube Cornish, 30ft. long, 7ft. 2in. diameter. Tube 2ft. 8in. in furnaces, and 2ft. 4in. beyond, 3/8 inch plates, 50 lbs. pressure. The left furnace crown collapsed and ruptured, and the right furnace crown was slightly altered in shape. The two boilers were connected by one feed pipe without back valves, so that the water from this boiler was forced into the other and allowed the tubes to be overheated. _No. 38. Liverpool. (Fig. 28.) September 8th. 1 killed, 1 injured._ [Illustration: _Fig. 28._] One tube Cornish, 22ft. 6in. long, 6ft. diameter, 3ft. tube, 7/16 inch plates, 55 lbs. pressure.
