The writings of Margaret Fuller possess a lasting value, and will continue to be read for their wit and wisdom, when those of her more ambitious companions are forgotten. For she treated ever-recurring themes in a living way--vigorous and original, but human. Her taste was educated by study of the Greek classics, and she had the appreciation of form that belongs to the literary order of mind. Her writings are not for those who read as they run, but for those who read for instruction and suggestion. As the number of such increases, it is not unreasonable to expect an increase in her audience. With her, thinking and talking were serious matters. She discussed nothing in a spirit of frivolity; her thoughts came from a penetrating, and not from a merely acute mind; the trains of reflection that she started are still in motion, from the momentum she gave, and the goal she aimed at is not yet discerned by professed disciples of her own ideas. The "Dial" is a treasury of literary wealth. There are pieces in it of prose and verse that should not and will not be lost. The character for oddity and extravagance which Transcendentalism bore in its day, and has borne on the strength of tradition ever since, would have to be borne no longer, if the contents of that remarkable magazine could be submitted to the calmer judgment of to-day. Not that the sixteen rich numbers contain a great deal that would be pleasing to the hasty mental habit of this generation, but to the lovers of earnest thinking and eloquent writing they have the flavor of a choice intellectual vintage. It is the misfortune of periodical literature to be ephemeral. The magazine sows, but does not harvest. It brings thoughts suddenly to the light, but buries them in season for the next issue, which must have its turn to live. Volumes that are compiled from magazines have lost their bloom. The chapters have already discharged their virtue, and spent their perfume on the air; the smell of the "old numbers" clings to the pages, which are not of to-day, but of the day before yesterday. We call for living mind, and fancy that butterflies, because we see them fluttering in the garden, are more alive than the phoenix that has risen unscathed from the ashes of consuming fires. The thoughts of William Henry Channing, though keen, brilliant, of great potency in their time, and admirable in expression, were addressed to the exigencies of the hour, and absorbed by them. Such as were committed to paper in the "Harbinger," the "Spirit of the Age," and other periodicals, will never be heard of again; and such as were printed in books passed from memory with the themes he dealt with. His biographical works deserve a place with the prominent contributions of that department.
