as sooin eat my supper off a tombstone as off wer kitchen table." He faced danger with reckless unconcern every day of his life. He was employed as a "vessel-man" at the Leeds Steel Works, working on a twelve-hours' shift, and his duty was to attend to the huge "vessels" or crucibles in which the molten pig-iron is converted by the Bessemer process into steel. The operation is one of enthralling interest and beauty, and Job Hesketh's soul was in his work. The molten iron from the blast furnaces flows along its channel into huge "ladles" or cauldrons, and from there it is conveyed into a still larger reservoir or "mixer," where the greater part of the slag--which floats as a scum on the surface--is drawn off. Then the purified metal passes into other cauldrons, which are borne along by hydraulic machinery and their contents gently tipped into the crucibles, which lower their gaping mouths to receive the daffodil stream of molten iron. When their maws are full, the crucibles are once more brought into an erect position, and the process of converting iron into steel begins. A blast of air is driven through the liquid metal, and the "vessels" are at once changed into fountains of fire. A gigantic spray of flame and sparks rises from their gaping mouths and ascends to a height of twenty feet, changing its colour from green to gold and from gold to violet and blue as the impure gases of sulphur and phosphorus are purged by the blast. For twenty minutes this continues, and then the roar of the blast and the fiery spray die down. What entered the crucible as iron is now ready to be poured forth as steel. Once more the "vessels" are lowered and made to discharge their contents. First comes a molten cascade of basic slag which is borne away to cool, then to be ground to finest powder, before its quickening power is given to pasture and cornfield, imparting a deeper purple to the clover and a mellower gold to the rippling ears of wheat. When all the slag has been drawn off, there is a moment's pause, and then a new cascade begins. The steel is beginning to flow, not in a daffodil stream like the slag, but in a cascade of exquisite turquoise blue, melting away at the sides into iridescent opal. Sometimes a great cloud of steam from the pit below passes across the mouth of the crucible, and then the torrent of molten steel takes on all the colours of the rainbow, and the great shed, with its alert, swiftly moving figures, is suffu
