Marine Upright, 13ft. 3in. high, 6ft. 6in. diameter, 1/2 inch plates. Internal fire-box 8ft. 6in. high, 6ft. diameter at bottom, 5ft. 3in. diameter at the top, 3/8 inch plates, 50 lbs. pressure. In the sketch the shell is shown in dotted lines to allow the internal fire-box to be seen. The boiler was rent into many pieces, many of which were lost in a river, so that a satisfactory conclusion as to the cause of the explosion was impossible. The boiler was not very firmly stayed, and it is supposed that it was weakened by corrosion round the fire doors. _No. 45. Hartlepool. December 29th. 1 injured._ Marine, with 3 internal fireplaces joined at the back. The back of the junction tube gave way at a place deeply corroded, and allowed the contents of the boiler to escape. * * * * * NOTE.--Two more illustrations may be given which are not sufficiently important to include in the above list. * * * * * _Willenhall. (Fig. 25.) December 24th. none injured._ [Illustration: _Fig. 25._] One of two. Plain Cylinder, 25ft. 6in. long, 5ft. 6in. diameter, 3/8 inch plates, 30 lbs. pressure. The water was allowed to get low, and the overheated plates opened and allowed the steam to escape harmlessly. _Stoke. (Fig. 26.) December 9th. none injured._ [Illustration: _Fig. 26._] One of eight. Four Furnace Upright, 22ft. high, 9ft. diameter, 7/16 inch plates, 45 lbs. pressure. The water was allowed to get so low that the shell was overheated and rent, and the side tube slightly collapsed, and the injury was not discovered until the feed water had risen up to the rupture, when it ran into the furnaces without causing any violent explosion, although cold water had been put into a red hot boiler. * * * * * STOURBRIDGE: PRINTED BY R. BROOMHALL, HIGH STREET. BOILER EXPLOSIONS IN 1869. _No. 1. Chesterfield. (Fig. 1.) January 14th. 4 killed, 2 injured._ [Illustration: _Fig. 1._] One of two. One tube Cornish, 26ft. 6in. long, 6ft. diameter, tube 3ft. 3in. diameter, 3/8 inch plates, 45 lbs. pressure. The gauge glass was broken and the float was either out of order or unobserved, as the water was allowed to get 9 inches below the usual level, so that the crown of the furnace became overheated and collapsed, and rent open where a patch had been put on some little time before. _No. 2. Manchester. (Fig. 2.) January 22nd. none injured._ [Illustration: _Fig. 2._] Locomotive. The barrel was 10ft. 6in. long, 4ft. diameter, 7/16 inch plates, 130 lbs. pressure. The engine was 14 years old, and had lately been tested to 180 lbs. hydraulic pressure. The seams near the bottom were so deeply "furrowed" or corroded just above the lap joint in a continuous line that they rent open. _No. 3. Greatbridge. (Fig. 3.) January 26th. 1 killed, 1 injured._ [Illustration: _Fig. 3._]
