STOURBRIDGE: B. BROOMHALL, PRINTER, HIGH STREET. 1869. BOILER EXPLOSIONS IN 1866. _No. 1. Nottingham. January 1st. none injured._ Locomotive, 110 lbs., standing with steam up near a platform. All but the fire box was blown away, the main portion being thrown a distance of 400 yards. The first rent took place at a longitudinal seam of the barrel where grooving had gone on very rapidly, which was not discovered when examined and tested a short time before. _No. 2. Walsall. (Fig. 1.) January 2nd. 2 injured._ [Illustration: _Fig. 1._] Butterley, 26ft. 6in. long, and 9ft. diameter. The wagon-shaped top to the fire place was 8ft. 6in. long, and was attached to the bell-mouth of the internal tube, which then continued circular to the back of the boiler. The tube was 3ft. 6in. diameter. All the plates were about 7/16ths inch thick, and although the boiler was an old one, they were nowhere reduced in thickness by wear. The usual pressure of steam was 18 lbs., and a self-registering gauge showed that at the time of explosion it did not exceed 20 lbs.
