Agricultural, 7ft. 6in. long, and 3ft. 8in. diameter, ¼ inch plates, 35 lbs., fire-box 2ft. long, and 2ft. 10in. broad. Two 11½-inch tubes led to an internal chamber at the other end of the boiler, and three 8¼-inch tubes led back again to an external smoke box and chimney fixed over the fire door.
The bottom of the right hand side lower tube was forced upwards, and rent along to within 12 inches of the fire-box.
The tubes were so corroded from leakage of patches, that they were unable to bear the slight increase of pressure during a short stoppage.
