A SERIOUS OUTBREAK AT NAUVOO.—The excite-ment in the State of Illinois is still on the increase, and, as if no disguise of their intentions were necessary, the Mormons seem to leave no opportunity untried to fan the flame which is every where raging around them, and which, it is feared, it not immediately extinguished, will soon end in a bloody civil war. At the landing of the steamer Sarah Ann at Nauvoo on Saturday, the 25th ult. James L. Bradley, the officer entrusted with the writ for the arrest of Redding, being on board, the latter was ob-served standing in a very unconcerned manner upon the wharf; whereupon Bradley sprang ashore and seized him as his prisoner. Redding immediately raised a cry for help, and was surrounded almost instantaneously by a strong body of Mormons, who began throwing large pieces of rock and other missiles at the officer and the passengers of the boat, whom he had called upon to aid him. A desperate struggle ensued, which might have resulted in the capture of Redding, had not one of the most conspicuous of the Nauvooites commanded the cit-izens to make use of their firearms; on which the pas-sengers retreated, and Redding was forcibly taken from the custody of Bradley, who, with his assistants, were obliged to imitate the example of the passengers by re-gaining the boat, which then put off. This affair created a deep excitement in the country wherever it was bruit-ed, and a meeting was afterwards held by the citizens of Fort Madison to consider the outrage, when a report, drawn up by the passengers and crew of the aforesaid boat, was read and commented on.
Bradley has started out once more, provided with a regular process, for the arrest of Redding. The result of this last attempt has not yet reached us.
