A little way off there was another indistinct figure; this one black, with a sustained hiss that spoke of strength very much in reserve. The long chimney running up beside an ash-tree, and the warmth which radiated from the spot, explained without the necessity of much daylight that here was the engine which was to act as the _primum mobile_ of this little world. By the engine stood a dark, motionless being, a sooty and grimy embodiment of tallness, in a sort of trance, with a heap of coals by his side: it was the engine-man. The isolation of his manner and colour lent him the appearance of a creature from Tophet, who had strayed into the pellucid smokelessness of this region of yellow grain and pale soil, with which he had nothing in common, to amaze and to discompose its aborigines.
