One of four. One tube, externally fired, 18ft. 6in. long, 6ft. 6in. diameter. Tube 3ft. diameter, 1/2 inch plates, 40 lbs. pressure. In sketch the shell is shown in dotted lines to allow the tube to be seen. The tube collapsed from end to end and ruptured at two seams, and the contents issued so violently as to knock down the brickwork and displace the boiler. The tube was in a very weak and corroded condition, and unable to bear the usual working pressure. _No. 35. Moxley. (Fig. 19.) September 28th. 13 killed, 2 injured._ [Illustration: _Fig. 19._] One of four. Four Furnace Upright, 22ft. high, 10ft. 6in. diameter, 7/16 inch plates, 40 lbs. pressure. The boiler was rent into nine pieces, one of which was not found. The dotted line in sketch shows the outline of the boiler before explosion, and the fragments are arranged as nearly as possible in their original position. The first rent was at a seam-rip opposite the largest furnace, from whence the rupture opened in every direction. This seam-rip must have existed some time before explosion, and must have extended from rivet to rivet, until the boiler was so much weakened as to be unable to bear the usual pressure. _No. 36. Winsford. September 30th. 1 killed._ Plain Cylinder. Few particulars obtained. The end over the fire burst open and allowed the contents to escape. A thick accumulation of scale on the bottom had caused the plate to become overheated by preventing proper contact of the water. _No. 37. Elsecar. (Fig. 20.) October 2nd. 2 killed._ [Illustration: _Fig. 20._] One of four. Two Furnace Upright, 21ft. high, 7ft. diameter, 7/16 inch plates, 58 lbs. pressure. A large piece of plate was blown out of the side of the boiler, and the reaction of the issuing contents threw the boiler over on to its side. The plate was said to be overheated from shortness of water, but as the centre tubes were uninjured, the ruptured plate may have become overheated from the intense heat impinging on one place, causing so rapid a generation of steam as to prevent proper contact of water. _No. 38. Glasgow. October 12th. 1 killed, 1 injured._ Plain Cylinder, 39ft. long, 5ft. diameter, 3/8 inch plates. A small piece of plate about one-and-half-feet area blew out of the bottom, and the contents issued so violently as to do much damage, although the boiler itself was not otherwise injured. The ruptured plate was corroded, to 1/16 inch thickness by the leaking of seams, caused by the feed water entering close to the bottom of the boiler. _No. 39. Swansea. October 13th. 2 killed, 1 injured._
