It is certainly easier, and far more agreeable, to read Charles Lamb's essays than to ask a stranger in which one of them he discovered the author's heterodox views on encyclopaedias. It involves no great fatigue to look up a poem of Herrick's, or a letter of Shelley's, or a novel of Peacock's (these things are accessible and repay enquiry), and it would be a rational and self-respecting thing to do, instead of endeavouring to extort information (like an intellectual footpad) from writers who are in no way called upon to furnish it. One thing is sure. As long as there are people in this world whose guiding principle is the use of other people's brains, there can be no decline and fall of letter-writing. The correspondence which plagued our great-grandfathers a hundred years ago, plagues their descendants to-day. Readers of Lockhart's "Scott" will remember how an Edinburgh minister named Brunton, who wished to compile a hymnal, wrote to the poet Crabbe for a list of hymns; and how Crabbe (who, albeit a clergyman, knew probably as little about hymns as any man in England) wrote in turn to Scott, to please help him to help Brunton; and how Scott replied in desperation that he envied the hermit of Prague who never saw pen nor ink. How many of us have in our day thought longingly of that blessed anchorite! Surely Mr. Herbert Spencer must, consciously or unconsciously, have shared Scott's sentiments, when he wrote a letter to the public press, explaining with patient courtesy that, being old, and busy, and very tired, it was no longer possible for him to answer all the unknown correspondents who demanded information upon every variety of subject. He had tried to do this for many years, but the tax was too heavy for his strength, and he was compelled to take refuge in silence. Ingenious authors and editors who ask for free copy form a class apart. They are not pursuing knowledge for their own needs, but offering themselves as channels through which we may gratuitously enlighten the world. Their questions, though intimate to the verge of indiscretion, are put in the name of humanity; and we are bidden to confide to the public how far we indulge in the use of stimulants, what is the nature of our belief in immortality, if--being women--we should prefer to be men, and what incident of our lives has most profoundly affected our careers. Reticence on our part is met by the assurance that eminent people all over the country are hastening to answer these queries, and that the "unique nature" of the discussion will make it of permanent value to mankind. We are also told in soothing accents that our replies need not exceed a few hundred words, as the editor is nobly resolved not to infringe upon our valuable time.
