Portable vertical, of peculiar construction, with return down flue tubes, 6ft. high, 4ft. 6in. diameter, 3/8 inch plates, 35 lbs. pressure. The shell was torn off, the bottom having given way through weakness, from want of proper stays, from the crown of the fire box to top of the boiler. _No. 29. Hull. (Fig. 17.) May 22nd. 3 killed, 1 injured._ [Illustration: _Fig. 17._] Lancashire, 22ft. 6in. long, 7ft. 6in. diameter. Tubes 2ft. 10in. diameter, 3/8 inch plates, 70 lbs. pressure. The tube was somewhat corroded on the top, and gave way over the fire from weakness. _No. 30. Bath. May 25th. 1 killed, 1 injured._ Revolving Rag boiler of plain cylindrical shape, but revolving on trunnions, in the opposite direction to No. 26, 12ft. high, 6ft. diameter, 9/16 inch plates, 50 lbs. pressure.

Tube collapsed from weakness, and partly tore away from the back end, and the reaction from the issuing contents forced the boiler back a long way. _No. 33. Tunstal (Fig. 20). June 28th. 8 killed, 20 injured._ [Illustration: _Fig. 20._] Cornish, 43ft. long, 6ft. 6in. diameter, 7/16 inch plates. Tube 3ft. diameter, 3/8 inch plates, 50 lbs. pressure. The tube collapsed sideways from end to end through weakness, being without strengthening hoops, and with continuous longitudinal seams. The back end and part of the tube were thrown to the rear, and the rest of the boiler was thrown to the front, and separated into several fragments. _No. 34. Glasgow. July 9th. 3 killed._ The lid of a steam valve was being removed while under pressure, and the steam escaped and scalded those near. _No. 35. Rotherham. (Fig. 21.)
