7/16 As the boiler was already worn out and unsafe for steam, we put no water into it and made no effort to prevent the tubes from shrinking. For fuel we used slabs from the sawmill. The fire box and boiler gave forth a great deal of heat, which rose through the layer of grass on the poles. We threw the grass in at the scuttles and spread it round in a layer about eighteen inches thick. As thus charged, the loft would hold about as much hay as grew on an acre. |
