The crown of the right hand tube became overheated from shortness of water, and bulged down and rent half round at the second seam of rivets. _No. 50. Durham. (Fig. 38.) November 2nd. 1 injured._ [Illustration: _Fig. 39._] One of four. Plain Cylinder, with the plates arranged lengthways, 38ft. long, 6ft. 6in. diameter, 3/8 inch plates, 35 lbs. pressure. A seam over the fire slightly to the right side gave way where there had been frequent repair to stop leaking. At the part which gave way there had formerly been a side fire, which had perhaps damaged the seams. This boiler was known to have been in bad condition and needing repairs. See No. 59. _No. 51. Sheerness. (Fig. 39.) November 3rd. 11 killed, 7 injured._ [Illustration: _Fig. 40._] One of three. Marine, 15ft. 6in. long, 6ft. diameter. Furnace Tube 2ft. 4in. diameter, 5/8 inch plates, 80 lbs. pressure. The left hand tube collapsed and ruptured, and the contents issued at the front and scalded all near. The right hand tube was also slightly out of shape on the top. The cause of the collapse was, that the water had been allowed to get below the crowns of the furnaces. There was no means of ascertaining how the shortness of water occurred, as all were killed who had the opportunity of knowing. _No. 52. Cornwall. (Fig. 40.) November 25th. 1 injured._ [Illustration: _Fig. 41._] One of five, 30 years old. One tube Cornish, 36ft. long, 7ft. diameter. Tube 3ft. 10in. diameter, 7/16 inch plates, 40 lbs. pressure. The shell was rent into several large pieces and thrown to some distance. The tube was also thrown out and broken, chiefly by its fall and striking against walls. The boiler was corroded very badly on the seating, which must have been known, as there were numerous small screw patches to prevent leaking at the corroded places. The shell was in such bad condition, that it was quite unfit to bear the ordinary working pressure. See No. 58. _No. 53. Bilston. (Fig. 42.) December 3rd. 8 killed, 1 injured._ [Illustration: _Fig. 42._] One of three. Four Furnace Upright, 20ft. high, 10ft. diameter. Centre tube 10ft. high, 4ft. 6in. diameter, side tubes 2ft. diameter, 3/8 inch plates, 35 lbs. pressure. The central tube collapsed, and the bottom part was blown out, and allowed the contents of the boiler to issue from the bottom into the culvert leading to the stack, and into the necks of the furnaces from which it was heated. The reaction sent the boiler up to a great height, and it divided into eleven fragments, which were very widely scattered. Comparatively little damage was done to the furnaces and premises, only the brickwork surrounding the boiler being thrown down.
