In June 1829 Tennyson scored his first triumph by the prize poem on Timbuctoo, which, as he said many years afterwards, won the medal to his utter astonishment, for it was an old poem on Armageddon, adapted to Central Africa "by a little alteration of the beginning and the end." Arthur Hallam wrote of it on September 2, 1829: "The splendid imaginative power which pervades it will be seen through all hindrances. I consider Tennyson as promising fair to be the greatest poet of our generation, perhaps of our century"--a remarkably far-reaching prophecy to have been built upon so slender a foundation. Out of his "horror of publicity," as he said, he committed it to Merivale for declamation in the Senate House. In 1830 appeared Tennyson's first volume of poems, upon which Arthur Hallam again wrote, in a review, that "the features of original genius are strongly and clearly marked"; while on the other hand, Coleridge passed upon it the well-known criticism that "he has begun to write verses without very well knowing what metre is"; and Christopher North handled it with a touch of good-natured ridicule. Then followed, in 1832, a fresh issue, including that magnificent allegory, the "Palace of Art"; with other poems whose very blemishes signified exuberant strength. James Montgomery's observation of him at this stage is in the main true as a standing test of latent potency in beginners. "He has very wealthy and luxurious thought and great beauty of expression, and is _a poet_. But there is plenty of room for improvement, and I would have it so. Your trim, correct _young_ writers rarely turn out well; a young poet should have a great deal which he can afford to throw away as he gets older." The judgment was sound, for after a silent interval of ten years, during which the Poet was sedulously husbanding and cultivating his powers, the full-orbed splendour of his genius shone out in the two volumes of 1842.
