One of five, 23 years old. Balloon, 16ft. diameter, 3/8 inch plates, 5 lbs. pressure. It ruptured at the back where the plates in contact with brickwork were reduced by external corrosion, and the bottom was forced down upon the grate, and the top rolled over on to its side. The boiler was not being used, although connected with the other at work. The strain upon the bottom was increased by the boiler being over full and nearly to the brim. Those near were drenched with nearly cold water from it when it upset.

Portable upright, about 8 years old, 11ft. 4in. high, 4ft. diameter, 3/8 inch plates, 100 lbs. pressure. The internal portion gave way where attached to the fire holes and collapsed inwards, and the reaction of the issuing contents forced the boiler up some distance on to the top of a house. The safety valve did not act properly, and the pressure appears to have accumulated to more than the boiler could bear, during a temporary stoppage of the engine.
