One of four. Plain Cylinder with round front and flat back end, 36ft. long, 6ft. diameter, 7/16 inch plates, 20 lbs. pressure.
The flat end was blown out, the rent extending all round the angle iron.
There had originally been a breeches tube in the boiler with a strong stay to the front end, but when this was taken out no stays were put to the flat end to compensate for the loss of their support. The angle iron attaching the flat end was made in four pieces instead of being welded, and it was reduced to 3/16 inch thick by external corrosion, so that it was not strong enough to bear the ordinary working pressure.
The extreme imprudence of altering boilers without due care to preserve their strength has been often pointed out. See [No. 21] and [No. 43].
