Domestic, the circulating pipes were frozen, and the accumulated pressure caused the boiler to rent open, but little damage was done. _No. 70. Burton. Date not ascertained. 1 killed._ Plain Cylinder, underground, internally corroded until too weak to bear ordinary pressure. * * * * * _R. Broomhall, Printer, Stourbridge._ BOILER EXPLOSIONS IN 1871. _No. 1. Tranmere. (Fig. 1.) January 1st. 1 injured._ [Illustration: _Fig. 1._] Domestic. Cast-iron, 1ft. 4in. wide, 1ft. high, and 11in. deep. The circulating pipes being frozen the pressure accumulated, and rent the boiler into pieces, doing great damage. _No. 2. Rochdale. (Fig. 2.) January 2nd. 1 injured._ [Illustration: _Fig. 2._] Plain cylinder, 11ft. long, 3ft. 1in. diameter, 3/8 inch plates, 25 lbs. pressure. Ruptured at a bad patch over grate, around which were many old cracks, and the rent passed along the bottom, and through the unguarded manhole, and round several of the transverse seams, dividing the boiler into 4 or 5 pieces, which were widely scattered, but are arranged in sketch near their original position. _No. 3. January 2nd. none injured._ Cornish, 32ft. long, 6ft. 6in. diameter, 3/8 inch plates, 30 lbs. pressure. Tube ruptured at first seam over the fire from weakness caused by internal corrosion. _No. 4. Middlesbro. (Fig. 3.) January 4th. 1 killed._ [Illustration: _Fig. 3._] Domestic, 1ft. 3in. wide, 1ft. high, 11in. deep, 5/16 inch thick. The circulating pipes being frozen, the pressure accumulated and rent the boiler open, doing considerable damage. _No. 5. Stirchley. (Fig. 4.) January 9th. 1 killed, 4 injured._ [Illustration: _Fig. 4._] One of five, about 30 years old. Lancashire, 18ft. 2in. long, 7ft. 6in. diameter. Tubes 2ft. diameter, 3/8 inch plates, 12 lbs. pressure. Ruptured at corroded steam pipe joint at top of front end, and the rent followed along the angle ring of shell which was also corroded, and then along the seams of some plates in the bottom, placed longitudinally, allowing the top of the boiler to open up like a lid, without moving it much out of its original position. _No. 6. Cornwall. January 12th. 1 killed._ Cornish, 30ft. long, 6ft. diameter, 7/16 inch plates, 35 lbs. pressure. The ball weight of the safety valve was unusually near the steam pipe, and it is supposed that the boy who was scalded having put his dinner on the pipe to warm, it slipped between the ball and pipe; and that in trying to extricate it he lifted the valve which was held open by the "pasty" wedged under the ball. _No. 7. Dalry. January 13th. 3 injured._
