Translations for telegraphic in French

Here are paragraphs from public domain books translated:

If the news had been of some other character, I have no doubt that the secret would have been carefully guarded by the telegraphic operator as well as by the officers of the vessel. But it was one of those events calculated to escape from the most rigorous discretion. The same day, no one knew how, the incident became a matter of current gossip and every passenger was aware that the famous Arsene Lupin was hiding in our midst.

Il se fût agi de toute autre nouvelle, je ne doute point que le secret en eût été scrupuleusement gardé par les employés du poste télégraphique, ainsi que par le commissaire du bord et par le commandant. Mais il est de ces événements qui semblent forcer la discrétion la plus rigoureuse. Le jour même, sans qu’on pût dire comment la chose avait été ébruitée, nous savions tous que le fameux Arsène Lupin se cachait parmi nous.
