_No. 24. Durham. (Fig. 18.) June 16th. 3 killed, 1 injured._ [Illustration: _Fig. 18._] One of three. Plain Cylinder, with plates arranged lengthways, 30ft. long, 6ft. 6in. diameter, 3/8 inch plates, 28 lbs. pressure, 25 years old. A seam gave way over the fire where there had been frequent repair, and the boiler was rent into two pieces, which were thrown to some distance. See No. 59. _No. 25. Airdrie. June 23rd. 2 killed, 3 injured._ Two tube Cornish, 35ft. long, 6ft. diameter. Tube 3ft. 2in. diameter over fire, and 2ft. diameter beyond, 50 lbs. pressure. The tube collapsed over the fire, having been very much weakened by frequent repair. _No. 26. Nuneaton. (Fig. 19.) July 5th. 3 injured._ [Illustration: _Fig. 19._] Plain Cylinder, 25ft. long, 4ft. 6in. diameter, 7/16 inch plates, 25 lbs. pressure. The plates along the line of rupture were corroded to 1/16 inch, and in some places much less, so that the boiler was quite unfit for the ordinary working pressure. _No. 27. Birmingham. (Fig. 20.) July 6th. 1 injured._ [Illustration: _Fig. 20._] Small Plain Cylinder, 5ft. long, 2ft. 2in. diameter, 1/4 inch plates, 25 lbs. pressure. Both sides of the boiler were corroded nearly through so that the strength was entirely gone, and it rent in two at the ordinary pressure. _No. 28. Wishaw. July 9th. 2 killed, 2 injured._ One of six. Breeches Tube. The tube or combustion chamber collapsed, having become overheated through shortness of water. _No. 29. Kidderminster. (Fig. 21.) July 16th. 1 killed, 4 injured._ [Illustration: _Fig. 21._] Plain Cylinder, 21ft. long, 4ft. 6in. diameter, 3/8 inch plates, 50 lbs. pressure. The boiler was very old and very much corroded. It had slightly rent open at some former time, and a most wretchedly made patch, shown in enlarged sketch, had been put on to stop leaking, made of thin sheets of iron inside and out and pasteboard between, held together by 36 slight bolts. Of course this patch did not restore the strength of the boiler, and it soon leaked badly, and the leaking hastened the corrosion of the plate below, until it was nearly eaten away, and quite unfit to bear the working pressure. _No. 30. Leeds. July 19th. 4 injured._ One of three, 12 years old. Two tube Cornish, 32ft. long, 7ft. 6in. diameter. Tube 2ft. 10in. diameter, 3/8 inch plates, 45 lbs. pressure. The right hand tube collapsed from end to end sideways, and ruptured in the furnace, and part of the tube was blown out. The cause of the explosion was simply the weakness of the tube without strengthening rings. _No. 31. South Wales. (Fig. 22.) July 19th. 1 killed._ [Illustration: _Fig. 22._] One of two. Plain Cylinder, 32ft. long, 5ft. diameter, 3/8 inch plates, 40 lbs. pressure. It gave way where deeply corroded on the inside. _No. 32. Burslem. (Fig. 23.) July 22nd. 1 killed, 3 injured._ [Illustration: _Fig. 23._]
