The boiler was blown completely out of the vessel, and the greater part of it fell into the water, and a large piece alighted on a crowded quay, but without doing any damage. The cause of the explosion was supposed to be over-pressure during a temporary stoppage of the engine. _No. 32. Barnard Castle. (Fig. 18.) June 11th. 2 injured._ [Illustration: _Fig. 18._] Agricultural, of about 7 horse power. The barrel of the boiler was 6ft. 1in. long, 2ft. 5in. diameter; the fire-box end was 3ft. wide, and 2ft. 4in. deep; the fire-box was 2ft. 5-1/2in. wide, and 2ft. 7in. high, and 1ft. 9-1/2in. deep, with 23 tubes passing from it through the barrel to the smoke box and chimney. The boiler was fitted with a 2in. safety valve, which was intended to blow at 45 lbs., but as there was no ferrule, it is supposed to have been screwed down to a much greater pressure. The upper portion of the shell over the fire-box rent through the manhole, and allowed the shell to open out and fall on each side. A large portion of the front plate was also torn off. The cause of the explosion was the weakness of the manhole, which was not strengthened by any ring, and also excessive pressure from want of proper safety valve. _No. 33. Breage. June 11th. 1 killed._ Cornish Boiler, 36ft. 6in. long, and 6ft. diameter, 3/8 inch plates, 45 lbs. The tube collapsed and rent, and the issuing contents caused the death of the attendant. The weak tube of such large diameter, was unable to bear the ordinary working pressure, having no strengthening rings. _No. 34. Nottingham. June 19th. 2 killed, 4 injured._ Locomotive, 1/2 inch plates, 140 lbs. The explosion occurred at the left hand side of the ring of plates in the barrel next the fire-box, and below the foot-plate. The rent tore along the edge of the lap and into the next ring of plates. The reaction of the issuing contents threw the engine off the rails. The cause of the explosion was partial corrosion at the point of rupture and strain of the plates, as the boiler itself formed part of the frame of the engine. _No. 35. Richmond. June 26th. 2 injured._ Locomotive, being tried for the first time. The funnel came in contact with a bridge, and the dome was also torn off. _No. 36. Gainsbro' June 29th. none injured._ No details have been obtained. _No. 37. Durham. July 2nd. 4 killed._ Plain Cylindrical Boiler, 30ft. long, and 6ft. diameter, 3/8 inch plates, 28 lbs. It had been repaired a short time before the explosion, with 5 new plates. The boiler was torn up into several pieces, but the main portion remained flattened out on the seating, while some smaller pieces were sent 250 yards away. The cause of the explosion was the deterioration of the boiler, and its frequent repair over the fireplace. _No. 38. Liverpool. June 12th. 4 injured._
