ARRIVED AT LAST. - The schooner Pamlico has at last arrived at Chicago. This vessel which has had a most remarkable voyage, left this port for Queenstown, Ireland, on the 10th of May, 1874, having a comparatively uneventful voyage. On the 3d of September of the same year she left Newcastle with a cargo of potash and sal-soda, and after getting as far as Newfoundland, was caught in a storm, and was compelled to return to England, where she arrived November 3rd. She immediately went into winter quarters, and after having been repaired, left on April 30th, 1875, for this port. After being out three days, she was again caught in a violent storm, and was compelled to put back to Crook Haven. She returned to Liverpool, and was converted from a schooner into a brigantine, and left that port on the 9th day of June. After encountering heavy weather and head winds, she arrived in the St. Lawrence River, having been out fifty-four days. She immediately left for this port and having arrived on Lake Huron during the storm of last week, and did not reach the Straights (sic), as was thought. She was caught in the storm of yesterday, opposite Milwaukee, and came before the wind, arriving at this port at ten o'clock last night. - Chicago Times, 17th.
