It was in his rambles afield in these directions and in his habitual afternoon and evening strolls to Enfield and back, that a delighted sense of the myriad activities of nature's life in wood and field and brook and croft and hedgerow began to possess Keats's mind, and to blend with the beautiful images that already peopled it from his readings in Greek mythology, and to be enhanced into a strange supernatural thrill by the recurring magic of moonlight. It is only in adolescence that such delights can be drunk in, not with conscious study and observation but passively and half unaware through all the pores of being, and no youth ever drank them in more deeply than Keats. Not till later came for him, or comes for any man, the time when the images so absorbed, and the emotions and sympathies so awakened, define and develop themselves in consciousness and discover with effort and practice the secret of rightly expressing themselves in words. After Keats, under the stimulus of Spenser, had taken his first plunge into verse, he went on writing occasional sonnets and other pieces: secretly and shyly at first like all other young poets: at least it was not until some two years later, in the spring of 1815, that he showed anything that he had written to his friend and confidant Cowden Clarke. This was a sonnet on the release of Leigh Hunt after serving a two years' sentence of imprisonment for a political offence. Clarke relates how he was walking in to London from Enfield to call on and congratulate the ex-prisoner, whom he not only revered as a martyr in the cause of liberty but knew and admired personally, when Keats met him and turned back to accompany him part of the way. 'At the last field-gate, when taking leave, he gave me the sonnet entitled _Written on the day that Mr Leigh Hunt left prison_. This I feel to be the first proof I had received of his having committed himself in verse; and how clearly do I remember the conscious look and hesitation with which he offered it! There are some momentary glances by beloved friends that fade only with life.' About a score of the pieces which Keats had written and kept secret during the preceding two years are preserved, and like the work of almost all beginners are quite imitative and conventional, failing to express anything original or personal to himself. They include the aforesaid Spenserian stanzas, which in fact echo the cadences of Thomson's _Castle of Indolence_ much more than those of Spenser himself; an ode to Hope, quite in the square-toed manner of eighteenth century didactic verse, and another to Apollo, in which style and expression owe everything to Gray; a set of octosyllabics recording, this time with some touch of freshness, a momentary impression of a woman's beauty received one night at Vauxhall, and so intense that it continued to haunt his memory for years; two sets of verses addressed in a vein of polite parlour compliment to lady friends at the seaside; and several
