Old Hickory and Old Ironsides. —We learn from the Boston Mercantile Journal that the Navy Commissioners have concluded it not best to hoist Old Hickory on to the cut water of the brigate Constitution, but have issued orders for the old head, which is a perfectly plain one, to be replaced. This is very well but what is to be done with the carved effigy of the “Old Roman” which has just been finished at the cost of three hundred dollars? Wouldn’t it be well for our Tammany folks to petition that it may be hung up in the Wigwam! With a little gilding it would answer a competent purpose by way of a “Golden Calf,” which the bronze worshippers would find very convenient to make their genuflections before.
