Yet we believe the impartial critic will confirm in every instance the decision. "Anacaona," written at Cambridge, was never published, because "the natural history and the rhymes did not satisfy" Tennyson; it is full of tropical warmth and ardour, with a fine rhythmic beat, but it is certainly below high-water mark. And the same must be said of the "Song of the Three Sisters," published and afterwards suppressed, though the blank verse of its prelude has undoubted quality. He acted, as we can see, inexorably upon his own rule that "the artist is known by his self-limitation"; feeling certain, as he once said, that "if I meant to make any mark in the world it must be by shortness, for the men before me had been so diffuse." Only the concise and perfect work, he thought, would last; and "hundreds of lines were blown up the chimney with his pipe smoke, or were written down and thrown into the fire as not being perfect enough." Yet all his austere resolution must have been needed for condemning some of the fine verses that were struck out of the "Palace of Art," merely to give the poem even balance, and trim it like a boat. Very few poems could have spared or borne the excisions from the "Dream of Fair Women"; though here and there the didactic or scientific note is slightly prominent, as in the following stanza: All nature widens upward. Evermore The simpler essence lower lies, More complex is more perfect, owning more Discourse, more widely wise. At any rate the preservation of these unpublished verses adds much to the value of the biography; and we may rank Tennyson among the very few poets whose reputation has rather gained than suffered by the posthumous appearance of pieces that the writer had deliberately withdrawn or withheld. Of Tennyson's own literary opinions one or two specimens, belonging to this time, may be given.
