The common run of orders, however, are sufficiently answered by the usual reply of "Ay, ay, sir!" which is the proper seaman's answer, where the repetition of the order is not necessary. But _some answer or other should always be made to an order_. This is a rule difficult to impress upon beginners, but the reasonableness of it is obvious, and it is well understood among all seafaring persons; and even though an officer should see that the man was executing his order, he still would require, and has a right to demand a reply. The rule is as strictly observed by the master and officers between themselves, as it is required by them of the men; for the reason is the same. It is almost unnecessary to say that the addition 'Sir' is always to be used in speaking to the master or to either of the mates. The mates in their turn use it to the master. 'Mr.' is always to be prefixed to the name of an officer, whether chief or second mate. In well-disciplined vessels, no conversation is allowed among the men when they are employed at their work; that is to say, it is not allowed in the presence of an officer or of the master; and although, when two or more men are together aloft, or by themselves on deck, a little low conversation might not be noticed, yet if it seemed to take off their attention, or to attract the attention of others, it would be considered a misdemeanor. In this respect the practice is different in different vessels. Coasters, fishermen, or small vessels on short voyages, do not preserve the same rule; but no seaman who has been accustomed to first class ships will object to a strictness as to conversations and laughing, while at day's work, very nearly as great as is observed in a school. While the crew are below in the forecastle, great license is given them; and the severest officer will never interfere with the noise and sport of the forecastle, unless it is a serious inconvenience to those who are on deck. In working ship, when the men are at their stations, the same silence and decorum is observed. But during the dog-watches, and when the men are together on the forecastle at night, and no work is going forward, smoking, singing, telling yarns, &c., are allowed; and, in fact, a considerable degree of noise and _skylarking_ is permitted, unless it amounts to positive disorder and disturbance. It is a good rule to enforce, that whenever a man aloft wishes anything to be done on deck, he shall hail the officer of the deck, and not call out, as is often done, to any one whom he may see about decks, or generally to have a thing done by whoever may happen to hear him. By enforcing this rule the officer knows what is requested, and may order it and see that it is done as he thinks fit; whereas, otherwise, any one about decks, perhaps a green hand, may execute the order upon his own judgment and after his own manner.
