Domestic, 1ft. high, 1ft. wide, 8in. across top, and 12in. across bottom, made of cast-iron, 7/16 inch thick. The fire had been let out sometime, and the circulating pipes to cistern 16ft. above were frozen, and on lighting fire steam was formed for which there was no escape, and the boiler was shattered. _No. 7. Sheffield. (Fig. 7.) February 14th. 2 killed, 1 injured._ [Illustration: _Fig. 7._] Domestic, used for warming rooms above, 2ft. 6in. wide, 2ft. high, 9in. across top, and 13in. across bottom, 3/8 inch plates. The circulating pipes to cistern, 12ft. above, were frozen, and steam was formed for which there was no vent, and boiler was rent open. The joints were so badly welded that they soon gave way, and little damage was done to property. _No. 8. Walsall. (Fig. 8.) February 19th. none injured._ [Illustration: _Fig. 8._] One of two. Plain cylinder, 12 years old, 30ft. long, 7ft. diameter, 1/2 inch plates, 50 lbs. pressure. The seams and plates were overheated by shortness of water, and gave way at ordinary pressure. It is supposed the water "kicked" into the other boiler, as there was no back valve to prevent this whenever one boiler happened to be fired a little harder, and consequently at slightly higher pressure than the other. There was no damage except to the boiler. _No. 9. Birmingham. (Fig. 9.) February 25th. none injured._ [Illustration: _Fig. 9._] Cornish, 5 years old, 32ft. long, 7ft. diameter. Tube 2ft. 4in. diameter, 7/16 inch plates, 30 lbs. pressure. Cracked along the bottom of front end where internally "furrowed." The boiler was not disturbed, but as the water escaped into an iron furnace the bricks were scattered, but little damage done. The boiler was intended for two tubes, and therefore there was a large part supported only by stays, allowing of a slight movement with varying pressure which facilitates the corrosion in certain lines of strain called "furrowing." In this case they were so close to the angle iron and filled with scale that they were difficult to detect. _No. 10. Cornwall. (Fig. 10.) March 17th. 5 injured._ [Illustration: _Fig. 10._] Upright Boiler, 2 ft. high, 1ft. 9in. diameter, 1/4 inch plates. It gave way where deeply corroded externally round the bottom angle iron. The top was blown through the roof and did considerable damage, the bottom being left in the grate. _No. 11. Sheffield. (Fig. 11.) March 27th. 1 injured._ [Illustration: _Fig. 11._] Agricultural or Contractor's Engine, 9ft. 2in. long, 2ft. 6in. diameter, 3/8 inch plates, 30 lbs. pressure. The heads of stays on each side were corroded outside and drew through the holes, allowing the angles of fire box to open. Boiler was not disturbed and no damage was done. _No. 12. Portsmouth. (Fig. 12.) March 29th. 3 killed, 1 injured._ [Illustration: _Fig. 12._]
