If these multifarious and important obligations, out of the ship, be fully complied with by the captain, he will seldom have more time left than is barely necessary to go on board--- just to see what is doing--to learn what has been done--and to give his orders, in a general way, to the first lieutenant, for his further guidance.
As a captain has not always the choice of his first lieutenant, it may sometimes happen that a person unfit to fulfil the duties of that office will be appointed.

Filling this station well implies not only knowledge and talents, but a disposition to enter cordially into the views of the captain, as well with regard to the general system of discipline, as to all the details of managing the ship.

When an unfit person is appointed, it is much better for the lieutenant, as well as the captain, that they should part; and certainly this is more conducive to the discipline of the ship, and therefore to the good of the service, than if they went on for ever like cat and dog.

This, indeed, is so well understood, that the Admiralty throw no obstacles in the way of officers exchanging.
In case the unfitness of the first lieutenant arises from absolute incompetence or negligence of his duties, it will soon appear in some palpable instance, for which he must be accountable before a court-martial, unless his captain permit him to quit the ship to avoid that alternative.

On the other hand, it will sometimes happen, that an officer who is both competent and zealous, is rather too fond of having his own way, and interpreting the rules and customs of the service in his own particular fashion, in opposition to the views of the captain.
