Every man on a warship has his little or big place that is his own and you must not cross its confines without permission. For instance, the starboard side of the quarter deck is the Captain's. You don't walk there unless he indicates that he would like to have you join him. The port side of the deck belongs to the other officers. The Captain almost never goes there, although, being the Captain, he can go where he pleases. Each officer's room is sacred when the curtain is drawn. And so on through the ship there is a little piece of territory sacred to each man or set of men. The fo'c'stle deck is the men's. Launch etiquette, however, is peculiar. One of the first things to learn about travelling in a naval launch is that it is a little ship of itself. You salute its deck, so to speak, when you enter it if you observe the niceties. The highest ranking officer sits in the stern and goes into the boat last. All the others stand until he seats himself. He is the first to leave and the others go in the order of their rank. You mustn't smoke in a launch in the daytime, and if you do so on the sly you must be sure not to show your cigar in passing the flagship, for the quartermaster on watch on the after bridge will report you and there'll be trouble. You mustn't smoke at night except by permission of the ranking officer on board. If you see him light a cigar or cigarette all the rest of you may do so. Otherwise you will please throw away your cigar or cigarette when you enter the boat. As you go out to your ship at night you hear the quartermaster on some other ship call out, "Boat ahoy!" and the coxswain of your boat answers with a yell, "Passing!" When you approach your ship or another to make a stop the coxswain must be particular about his answers to the boat ahoy call. If he has the President of the United States aboard, as coxswains on the Louisiana have had repeatedly, he calls out: "United States!" If an Admiral is on board the answer to the hail is: "Flag!" If a Captain is on board the answer is the name of his ship. If other commissioned officers above the grade of midshipmen are on board the answer is "Aye! aye!" and if the launch contains only midshipmen or other officers of lower grade the answer is, "No! No!" as if to say you needn't bother about this bunch. If it has only enlisted men on board the call is "Hello!" By these answers the officer of the deck is informed as to who is approaching. Of course they are used only in the night, for in the day time observation will reveal the situation.
