McDonald who assaulted him behind a few days since, has been apprised of at various times and from different sources.It will be seen that ha then and there saved the life of the ruffian who for more then twelve months has been secretlywatching an opportunity to take his.Of the visit of the people of Covington and vicinity toAtlica on ibat occasion, we only repeat now what we have explained heretofore time and again, that it was sir icily legal in its organization, and peaceful in its purposes. The people went in compliance with the call ol the engineer end sub-superintendent, who had been shamefully insulted, their orders outraged and despised by a mob of boaimen two days previous. The officers of tho law were with them, and had called them Jfo assist, if necessary, in the service of legal process.The fighting which was ensued was confined to but tbreo or four, and was the result of unexpected and temporary excitement. In this Mr. Hannegan did nut participate, but used every exertion in his power to quell it; and to such an extent that bo more than once placed himself before his friend* who were in the act of striking, incurring the greatest danger of being struck by them in their phrensy.— Jlo caught the club from the hands of a highly excited man at tho instant it was descending upon McDonald’s head, who lay prosirale in the edge of the water with hie lace up; and that blow, if given, must have been instantly fatal. He repeatedly called out not to kill him, and whilst turning to take a club from the bonds of another man who was advancing | within a few feet with threatening out-i cries, he called to Mr. Martin and others near, to save McDonald from drowning.
