Yesterday was a most disgraceful day for Minneapolis - filling the city with insults and challenges, noise, knock-downs and mob-law from morning until night. The direct source of all the evil seems to have resulted in the indescretion of a band of "calithumpians," who, returning the night before from a tin-pan serenade around a newly-married couple in Minneapolis, took occasion to hang up an image near the post office, with a string of potatoes around its neck, representing and effigy of Ireland's patron saint. The effigy was discovered in the early morning, by a little knot of Emeralders, who went at work to seek out the author of the indignity. They inquired at the adjacent stable of Mr. Kingsbury, but a total ignorance seemed to prevail as to the whereabouts of "the mon that hung it up," and the inquirers left. At this stage of the investigation, a by-stander, in the stable, probably to have a little fun by seeing what an effect such an expose would have, told his comrades that "if they would back him" he would go out and tell the devotees of the suspended saint that he made the image, and hung it up. No sooner said than done; they promised, and he appeared before the Hibernians and "announced himself." With a characteristic spirit they "pitched into him," and meted out to him an unmerciful thrashing. They knocked him down and kicked him, and he finally escaped them very severly injured. Only one of the aggressor's companions come to his defence, who knocked down one of the party, and then get out of danger as quick as possible. The Irish then pulled down the effigy and quit the field. The fight had broken out, and now the parties could not be content without mutual insults and aggravations. Some boys constructed two more effigies in the afternoon, and erected them on the corner of 1st and Bridge streets. Eight or ten Irishmen in the vicinity, incensed at the exhibition, again attempted to pull them down, but they were met and repulsed with considerable injury. Several of them were knocked down and the others received more or less blows without giving any that were effective. Here the shameless exhibition was arrested for a little while; the effigies stood their ground, and the defeated band of Irishmen fled across the river for reinforcements. By this time, three or four hundred people had assembled from all parts of the town. The worshippers of St. Patrick soon re-appeared on the ground, armed with rocks, shillalahs and pistols; now numbering from thirty to fifty. In "taking the field," they met with no resistance. Before their arrival, their patron saint had been "burned in effigy," and they were not long in demolishing the rest of the insulting caricatures. During the remainder of the day this band refreshed itself with bragging and bullying; swearing, threatening and challenging; some of them stripping down to the waist and offering themselves as champions, and the lesser satelites marching defiantly around the square, brandishing their clubs, rocks and revolvers, howling hideously and making the most blasphemous and extravagant demonstrations of war. At this juncture, the crowd exactly resembled the popular impression of a regular Kilkenny row. The rioters challenged the world in general and "Yankee Doodle" in particular, to "jist a little round," but their beligerent propensities were not gratified. They marched through the streets and into houses, insulting and elbowing all they met, and the proprietors of stores were obliged to defend their property in [one] instance with a pitchfork, and in others with fire-arms. The banks of the river, the streets and house-tops were filled with people, whom morbid curiosity had attracted as witnesses. Finally, after having the whole battle to themselves till they were tired, the Hibernians retraced their steps across the river, and the anarchy turned again to quiet. - The only Irishman we saw during the day, who exhibited the least evidence of sanity, was a ragged and melancholy-looking fellow, who stripped a decent coat off from one of the effigies, put it upon his own back and thoughtfully departed. He was a philosopher. There was no renewed outbreak in the evening as had been feared. Sheriff Lippincott was on the ground during the day, but attempted no arrests. There were four or five who should have suffered for their violent breach of the peace, but, with no municipal organization and no jail that will hold a man, it was almost impossible to make any arrests that would be successful in bringing the prisoners to justice.

We have but a word to say about this disgraceful affair. It commenced with a trick perpetrated by some sportive boys from a lore of mischief, which unlettered superstition, and blind veneration for a patron saint easily tortured into malice. As provokers of the quarrel, though thoughtless, the boys were wrong. They had no right to either hang or burn "St. Patrick" in effigy - no right to insult the spirit of any religion, though they believe the worshipers are dupes, and the founders imposters instead of saints. On the other hand, the Irish should not be so easily and foolishly provoked. If they would be more forbearing under what they conceive to be provoking insults, they would receive more regard as peaceful citizens, more respect as Romanists, fewer broken heads as aggressors and retaliators, and less censure for wilful ignorance, crime, bigotry and brutality. Let all our citizens cherish mutual forbearance and toleration.
