One of four. One tube Cornish, 26ft. 4in. long, 6ft. 6in. diameter. Tube 3ft. 9in. diameter, 3/8 inch plates, 15 lbs. pressure. The dotted line shows outside shell of boiler. The tube collapsed from end to end while the steam was being raised, owing to the weakness of so large a tube without strengthening rings.

One tube Cornish, 18ft. 3in. long, 4ft. 10in. diameter, 3/8 inch plates. Tube 3ft. diameter, 5/16 inch plates. In sketch the external shell is shown in outline to allow the tube to be seen. The tube collapsed owing to shortness of water, and rent open at one seam, allowing the contents to issue violently, although the boiler itself was not disturbed.
