So he loved La Lison, which started quickly and stopped sharp, like a vigorous and docile steed; he loved it because, apart from his fixed wages, it earned him cash, thanks to the gratuities on the consumption of fuel. Its excellent vaporisation effected, indeed, considerable economy in coal. It merited but one reproach, that of requiring too much oil. The cylinders, particularly, devoured unreasonable quantities of this liquid. They had a constant appetite which nothing could appease. In vain had he sought to moderate it. The engine lost breath at once. Its constitution required all this nourishment. Ultimately, he had made up his mind to tolerate the gluttonous passion, just as the eyes are closed to a vice in people, who, in other respects, are full of qualities. Whilst the fire roared, and La Lison was gradually getting up steam, Jacques walked round and round the engine, inspecting it in all its parts, endeavouring to discover why, in the morning, it should have put away more oil than usual. And he found nothing amiss. The locomotive was bright and clean, presenting that delightful appearance which indicates the good, tender care of the driver. He could be seen wiping, and furbishing the metal incessantly, particularly at the end of a journey, in the same manner as smoking steeds are whisked down after a long run. He rubbed it vigorously, taking advantage of its being warm, to remove stains and foam more perfectly. He never played tricks with his locomotive, but kept it at an even pace, avoiding getting late, which would necessitate disagreeable leaps of speed. And the two had gone on so well together, that not once in four years had he lodged a complaint in the register at the depôt, where drivers book their requests for repairs--the bad drivers, drunkards or idlers, who are ever at variance with their engines. But truly, on this particular evening, he had the consumption of oil at heart; and there was also another feeling, something vague and profound, which he had not hitherto experienced--anxiety, distrust, as if he could not rely on his engine, and wanted to make sure that it was not going to behave badly on the journey. Pecqueux was not there, and when he at length appeared, with flushed countenance, after lunching with a friend, Jacques flew into a rage. Habitually the two men agreed very well, in that long companionship, extending from one end of the line to the other, jolted side by side, silent, united by the same labour and the same dangers.
