It is a primary rule of the military service of the country that an officer must be a gentleman. That means that good breeding, consideration for the feelings of others, kindness, tact and all the other well known qualifications used in defining the word gentleman must govern the conduct of an officer. Good form also requires that there must be no discussion of subjects in the mess that would lead to discord, such as religion or politics. The result is that to the person not familiar with the traditions an officers' mess on board a warship seems to be a place for small talk or else for shop talk. Really there are few places in the world where the word gentleman has a better exemplification. The officers adapt themselves to the situation of enforced close intimacy of months and months in a way that excites admiration. You see, you've got to live with a person to find him out. When you touch elbows with him all the time all his little peculiarities stand out and all his annoyances of manner become conspicuous. The one social task on a ship is to ignore all these things and try to have a companionship as genial as if one's good points alone were on view for a day or two.

Keeping in good humor is the trick. One way in which this is done on ship is by a light chaffing that runs through the intercourse of the members of the mess. Probably no more skilful skating on thin ice takes place around any board than in the wardroom of a warship. Good natured thrusts and parries are going on all the time, and just as the danger point of going too far in personal matters is reached the talk is shifted in some mysterious way, and a new tack is taken.

A favorite means of fun is to tackle the mess caterer, as the treasurer is called, and tell him what poor food he is serving. Now, every man knows he is trying to make the mess money go as far as possible, and also to provide good food. He has a thankless job and the members of the mess like to run him, as the expression goes. Suppose he serves up that delightful concoction of domestic economy, meat balls. The running fire of comment on such fare would make any ordinary man's hair gray in a month. The members of the mess even go so far as to tell him that when he dies his monument should be topped with a marble representation of a dish of meat balls.

Let some man appear in evening dress after word has been passed that for once such a costume may be omitted at dinner. The luckless one is howled out of the wardroom and invited to set 'em up when he comes back. Let a man make some wild or foolish statement or boast; he never hears the last of it. Perhaps the chief engineer may get permission not to wear evening dress for an evening or two while he is fixing up some dirty work in the engine room. Some one will sing out:

"Captain, I work so hard; please excuse me from dressing for dinner." Forthwith the Fourth Ward, as the lower end of the table is called, gets up a yell and at a signal this is heard:

Bill Johnson! Bill Johnson! Bill Johnson!

I—work—so—hard!

Johnson, Johnson, Johnson!

Bill says it is on him and what'll ye have?

Let some one declare that he is on the water wagon and decline to join in a friendly glass. Forthwith over his place at the table will appear the H. T. T. banner, which, being interpreted, means Holier Than Thou, and the man says he'll stay on the wagon if you don't object, but will the others please order what they'd like at his expense.
