Among the several qualifications of a good friend, this wise man has very justly singled out constancy and faithfulness as the principal: to these, others have added virtue, knowledge, discretion, equality in age and fortune, and, as Cicero calls it, _Morum comitas_, "a pleasantness of temper." If I were to give my opinion upon such an exhausted subject, I should join to these other qualifications a certain equability or evenness of behaviour. A man often contracts a friendship with one whom perhaps he does not find out till after a year's conversation; when on a sudden some latent ill-humour breaks out upon him, which he never discovered or suspected at his first entering into an intimacy with him. There are several persons who in some certain periods of their lives are inexpressibly agreeable, and in others as odious and detestable. Martial has given us a very pretty picture of one of this species, in the following epigram: _Difficilis_, _facilis_, _jucundus_, _acerbus es idem_, _Nec tecum possum vivere_, _nec sine te_. _Ep._ xii. 47. In all thy humours, whether grave or mellow, Thou'rt such a touchy, testy, pleasant fellow; Hast so much wit, and mirth, and spleen about thee, There is no living with thee, nor without thee. It is very unlucky for a man to be entangled in a friendship with one who, by these changes and vicissitudes of humour, is sometimes amiable and sometimes odious: and as most men are at some times in admirable frame and disposition of mind, it should be one of the greatest tasks of wisdom to keep ourselves well when we are so, and never to go out of that which is the agreeable part of our character. CHEVY-CHASE. Part One. _Interdum vulgus rectum videt_. HOR., _Ep._ ii. 1, 63. Sometimes the vulgar see and judge aright. When I travelled I took a particular delight in hearing the songs and fables that are come from father to son, and are most in vogue among the common people of the countries through which I passed; for it is impossible that anything should be universally tasted and approved by a multitude, though they are only the rabble of a nation, which hath not in it some peculiar aptness to please and gratify the mind of man. Human nature is the same in all reasonable creatures; and whatever falls in with it will meet with admirers amongst readers of all qualities and conditions. Moliere, as we are told by Monsieur Boileau, used to read all his comedies to an old woman who was his housekeeper as she sat with him at her work by the chimney-corner, and could foretell the success of his play in the theatre from the reception it met at his fireside; for he tells us the audience always followed the old woman, and never failed to laugh in the same place.
