During the cruises he tries to pierce to the soul of that mysterious race, the sailors. For those who have preached to country and city folk the task is not easy. The sailors, artless and at the same time instructed by their travels, used to danger and to duty, do not take to specious rhetoric or childish advice. Hyperbole and platitude displease them equally. They have minds like the fishermen and workingmen whom of old John the Baptist or Jesus persuaded. One must search their heart rather than their reason, their imagination rather than their intelligence. In this way the preaching may bring them some simple truths, admonish their rather loose impulses, and give them resignation for their fatiguing tasks. Every Sunday religious service is held on board; it is a simple and dignified ceremony. Around the portable altar, the flags make stained windows; the arch of the church is replaced by the low whitewashed ceiling between decks; to right and left the partitions of the cabins, the white bodies of the stacks form the metallic walls of our temple; variegated funnels, valves, well-polished faucets, throw out sparkling reds and yellows; chairs for the officers, benches for the crew, cover eight or ten meters of the space. Anyone who wishes attends. A bugle call announces the Mass, and anyone not on duty may be present or may excuse himself. While the priest recites, one hears the respiration of the engines below, the snorting of the ventilators; overhead on deck tramp the sailors of the watch; the great waves of the Adriatic slap against the hull, and the quiver of the moving ship makes the altar tremble. Now and then there is music, old liturgic airs and modern themes. The priest addresses the sailors. He does not need to teach them heroism, to make fine phrases. The instinct of the sailors is surer. They are convinced by eternal truths, discussed with sincerity. Our Bretons, our Provençals, listen receptively to the gospel of the day. When they hear simple words, like those the Galilean used two thousand years ago, their lips are parted, their deep eyes become absorbed, their souls grow better. But if they hear argument, they make an effort to understand, they knit their brows, they discuss within their own minds. They reflect what is good and clear and simple; one is sure to touch them when one seeks their hearts. The _Domino, salvam fac rempublicam_ is played. The priest passes between the rows on his way to his cabin, and the congregation disperses. Five minutes later, benches and flags have disappeared, the place has recovered its solitude and its calm. The sailors before the engines or behind the guns remember with pleasure what they have just heard. Believers or not, they know that sincere words have been spoken and yield themselves to their influence.
