Not even the Whiteboys would injure him or the mails he carried.

He could say with pride, that in the most disturbed times his cars had never been molested.

Even during the Whiteboy insurrection, though hundreds of people were on the roads at night, the traffic went on without interference.

At the meeting of the British Association in 1857, Bianconi said: "My conveyances, many of them carrying very important mails, have been travelling during all hours of the day and night, often in lonely and unfrequented places; and during the long period of forty-two years that my establishment has been in existence, the slightest injury has never been done by the people to my property, or that entrusted to my care; and this fact gives me greater pleasure than any pride I might feel in reflecting upon the other rewards of my life's labour." Of course Bianconi's cars were found of great use for carrying the mails.

The post was, at the beginning of his enterprise, very badly served in Ireland, chiefly by foot and horse posts.
