The Pensacola (Fla.) Observer gives the particulars of the burning of the dry-dock there as follows: The dry-dock, originally intended to have been sunk in the channel to obstruct the passage of war steamers into our harbor, but which, from necessity, not choice, was sunk in the bay, about midway between Pickens and the yard, was burned to the water's edge last night. Who the perpetrators of this act were, is solely a question of speculation, as we go to press, though the Yankees have the general credit of it. Upon this point, however, we soon will be fully enlightened, but upon the point that we have lost over half a million of dollars by the operation our mind is perfectly clear and settled.
