The tube collapsed over the fire. It was so much thinned by corrosion, and so many of the rivet heads were eaten off, that there was not strength left to bear the ordinary pressure. _No. 39. Boxmoor. (Fig. 29.) September 10th. 1 killed, 4 injured._ [Illustration: _Fig. 29._] One of three. One tube Cornish, 27ft. 3in. long, 5ft. diameter. Tube 2ft. 10in. over furnace, and 2ft. 8in. beyond, 3/8 inch plates, 40 lbs. pressure. One ring of plates was blown out of the back end of shell. There was such extensive external corrosion on the seating at the bottom that the boiler was unable to bear the working pressure. _No. 40. Hull. (Fig. 30.) September 16th. 1 killed, 1 injured._ [Illustration: _Fig. 30._] Breeches Tube, 13 years old, 30ft. long, 7ft. diameter. Furnace tube 2ft. 10in. diameter. Main tube 3ft. 5-1/2in. diameter, and originally made to work at 20 lbs. pressure, but working lately at 45 lbs. The main tube collapsed. The boiler was not adapted for the pressure at which it was worked, and the tube was much weakened by the overheating caused by a thick incrustation of scale, and was not strengthened by any rings or stays, and was of very weak construction as the plates were arranged lengthways. _No. 41. South Wales. (Fig. 31.) September 26th. 1 killed, 1 injured._ [Illustration: _Fig. 31._] One of two, 20 years old. Plain Cylinder, 36ft. long, 6ft. 6in. diameter, 9/16 inch plates, 35 lbs. pressure. The plates and rivet heads were very much reduced in thickness by internal corrosion, and in many places were only 1/8 inch or less. _No. 42. Warrington. October 6th. 2 killed, 6 injured._ One of seventeen. Two tube Cornish, 22ft. long, 7ft. 6in. diameter. Tube 2ft. 6in. diameter, 7/16 inch plates, 45 lbs. pressure. The left hand tube collapsed. The blow-off cock was left open until the water was so low as to allow the tube to be overheated. _No. 43. Rowley. (Fig. 32.) October 13th. none injured._ [Illustration: _Fig. 32._] Plain Cylinder, with flat ends, 15ft. long, 3ft. 10in. diameter, 3/8 inch plates, 25 lbs. pressure. The back end ripped all round the angle iron, and was blown out, and the rest of the boiler was thrown forward a considerable distance. There had once been an internal tube, and when this was taken out the flat end had no stay, and was unfit to bear the usual pressure. See No. 47. _No. 44. Newcastle. (Fig. 33.) October 14th. 2 killed, 5 injured._ [Illustration: _Fig. 33._] Plain Cylinder, with plates arranged lengthways, 29ft. long, 6ft. diameter, 3/8 inch plates, 25 lbs. pressure. Although only 3 years old the boiler had always given trouble, and had been very frequently repaired. Some new plates had just been put in the bottom, and as the primary rent was in the old plates adjoining them, it is most likely they had caused seam rips in the old metal.
