The door was now becoming red-hot, lighting up the legs of both of them with a violet gleam. But neither felt the scorching heat in the current of icy air that enveloped them. The fireman, at a sign from his chief, had just raised the rod of the ash-pan which added to the draught. The hand of the manometer at present marked ten atmospheres, and La Lison was exerting all the power it possessed. At one moment, perceiving the water in the steam-gauge sink, the driver had to turn the injection-cock, although by doing so he diminished the pressure. Nevertheless, it rose again, the engine snorted and spat like an animal over-ridden, making jumps and efforts fit to convey the idea that it would suddenly crack some of its component pieces. And he treated La Lison roughly, like a woman who has grown old and lost her strength, ceasing to feel the same tenderness for it as formerly.
