On Friday some half dozen emigrants “from the county of Longford, Ireland,” challenged as many “from the county of Kildaire” to a trial of strength; and accordingly, a boxing match took place on that day at South Boston. One of the parties being worsted, obtained an accession of strength and renewed the skirmish on Saturday in good earnest. Sunday, following, suspended their riotous proceedings, only however, to be renewed with greater violence. And on Monday, rallying their forces to the number of about one hundred and fifty on a side, with shillelahs, and naked fists, they commenced a battle which would have ended with the loss of lives, had not the civil authorities interposed to quell it; which, however, they were only able to do by ringing the bells and giving the alarm of fire; thus calling the engine companies and a multitude from the city to the scene of the affray. Some of the ringleaders, have been apprehended and imprisoned, to wait a proper examination. Many were injured in a slight degree, and some seriously. Balt. Gaz.
