During the year 1746, Hervey wrote to a friend several long and very valuable letters on the doctrine of the Trinity. These may be found in his collected works, and are well worth reading. He also, as was his usage, carried on an extensive correspondence concerning experimental and practical religion; and his letters, belonging to this class, though occasionally verbose and fanciful, are characterized by the devoutest piety. None but a godly man could have written them; and none but godly people will peruse them. Many of them are almost little sermons, and all of them are rich in religious truth. In the days of penny postage, letters like these are rarely written; and it is greatly to be feared, that, English biographers in future centuries, will find a vexatious lack of biographical material belonging to this. People are too busy to write long letters; and, were it otherwise, the removal of the heavy postage of olden times has taken away one of the chief stimulants to make a letter longer than the pressing necessities of the case demand. Besides, locomotion is now so easy, cheap, and rapid, that friends, instead of sending their secrets to each other, in a written form, prefer to make a railway trip, and to tell them _viva voce_. Things were widely different a hundred years ago; and, hence, the extensiveness, richness, the fulness, and detail, the confidential gossip, and the heart-outpourings found in the correspondence of our English ancestors. They wrote letters: their grandsons send telegrams. The letters are of the greatest use to those who wish to become biographers. The telegrams are usually burnt as soon as they are read. In former days, letters were too long, interesting, and valuable to be destroyed. At the present day, they are too brief and common-place, to be worth preserving. The results of such a change in the epistolary habits of the people, are not felt at present; but they will be bitterly lamented in the approaching future. Not to mention other distinguished men belonging to the past, the most eminent of the Oxford Methodists all excelled in epistolary correspondence. Wesley’s collected works alone contain nine hundred and twenty-three of his private letters; Whitefield’s works, when published, even more than a hundred years ago, contained one thousand four hundred and sixty-five; while the works of short-lived Hervey, by far the _longest_ letter writer of the three, contain two hundred and nine, to all of which must be added hundreds more, published in other forms. In a book like this, it is impracticable to do more than very sparingly employ such copious materials; and nearly all that is attempted, in the case of Hervey, is to give only extracts containing incidents. These, however, shall be as exhaustive as possible. Proceeding on this plan, the following belong to the year when Hervey first became an author.
