As our rebel friends see their shot falling short of us, the firing ceases, and thus harmlessly ends the action which for a few moments threatened so much, teaching us the folly of too near approaches to land, or attempts to batter down, to which we have often been tempted, the earthworks daily erecting. It is folly to attempt it, because the disabling of these few blockade steamers would open the port to all who choose to barter with our Southern foes; and, _en passant_, this will explain why here and elsewhere the rebels build their works under the very noses of our men-of-war. Thus a vessel runs the blockade, and takes into them English Whitworth guns, which send balls flying through the air a good five miles, and whose range is longer than our far-famed Parrott rifled cannon. These Whitworths they place concealed in hillsides, or in forests back of the places where they build the regular fort to protect them. If our vessels approach to batter down these germs of forts, fire is opened on us from these long rangers, and nine chances out of ten we are disabled before we can so much as touch them with our guns; so that for ourselves we accomplish nothing, thereby benefiting them. Week days and Sundays pass on alike as far as outside incident is concerned, but new features in each other open to view as time goes on. Naval discipline develops the bump of reverence, or at any rate fosters it for a time, and to the volunteer in his first days or weeks passed on board a man-of-war, the dignified captain in the retirement of his cabin is an object of veneration, and the slight peculiarities of some other officers, merely ornamental additions to shining characters. On a Sunday, for instance, in the early part of the cruise, the said bump receives as it were a strengthening plaster, at the sight of officers and men in full dress--the first resplendent in gold-banded caps--multiplied buttons--shining sword hilts, et cetera, et cetera, and the men in white ducks, blue shirts, et cetera, scattered about the decks in picturesque groups. The captain, from the fact of his occupying a private cabin, and seeing the officers merely to give orders or receive reports in the line of their duty, comes but little in contact with them, and, as there is a certain idea of grandeur in isolation, obliges a degree of reverence not accorded to those with whom one is in constant intercourse. A slight feeling of superiority always exists in the minds of those of the regular navy over the volunteer officers, and though at first the ward-room mess all seemed 'hail fellow, well met,' familiarity develops various traits and tendencies, which, in a mess of eight or nine, will not be persuaded to form a harmonious whole. Our lieutenant, for instance, who, in the first days of the cruise, appeared a compound of all the Christian graces, and a 'pattern of a gentleman,' develops a pleasant little tendency to swear viciously on slight
