"What is the matter? Why, it goes beautifully!" said the fireman.

"No, no," answered Jacques; "I am uneasy."

And, notwithstanding each part of the locomotive being in good condition, he continued to toss his head. He turned the handles, assured himself that the safety-valve worked well, got on to the frame-plate, and attended to the grease-boxes of the cylinders himself; while the fireman wiped the dome, where a few slight traces of rust remained. Nothing was wrong with the sand-rod. All this should have set his mind at ease.

The fact was, that La Lison no longer stood alone in his heart. Another tenderness was growing there for that slim, and very fragile creature, whom he continued to see beside him on the bench in the garden of the square. A girl so gentle, so caressing, so weak in character, and who needed love and protection. Never, when some involuntary cause had put him behind time, and he had sent his engine along at a speed of sixty miles an hour, never had he thought of the danger the passengers might be incurring. And, now, the mere idea of taking this woman back to Havre, this woman whom he almost detested in the morning, whom he brought up with annoyance, caused him great anxiety, and made him dread an accident, in which he imagined her wounded by his fault, and dying in his arms. The distrusted La Lison would do well to behave properly, if it wished to maintain the reputation of making good speed.

It struck six. Jacques and Pecqueux climbed up to the foot-plate, and the latter, opening the exhaust-pipe at a sign from his chief, a coil of white steam filled the black engine-house. Then, responding to the handle of the regulator which the driver slowly turned, La Lison began to move, left the depôt, and whistled for the line to be opened. Almost immediately the engine was able to enter the Batignolles tunnel, but at the Pont de l'Europe it had to wait; and it was not until the regulation time that the pointsman sent it on to the 6.30 express, to which a couple of porters firmly secured it.

The train was about to leave; it wanted but five minutes to the time, and Jacques leant over the side, surprised at not perceiving Séverine among the swarm of passengers. He felt certain she would not seat herself without first of all coming to the engine. At last she appeared, behind time, almost running. And, as he had foreseen, she passed all along the train and only stopped when beside the locomotive, her face crimson, exulting with joy.

Her little feet went on tiptoe, her face rose up, laughing.

"Do not be alarmed!" she exclaimed. "Here I am."

He also laughed, happy to see her there, and answered:
