Some inquirers, in interpreting these accounts, have judged that the personal introduction did not take place in the spring or early summer at all, but only after Keats's return from his holiday at the end of September. I think it is quite clear, on the contrary, that Clarke had taken Keats up to Hampstead by the end of May or some time in June. Unmistakeable impressions of summer strolls there occur in his poetry of the next few months. The 'happy fields' where he had been rambling when he wrote the sonnet to Charles Wells on June the 29th were almost certainly the fields of Hampstead, and there is no reason to doubt Hunt's statement that the 'little hill' from which Keats drank the summer view and air, as told at the opening of his poem _I stood tiptoe_, was one of the swells of ground towards the Caen wood side of the Heath. At the same time it would seem that their intercourse in these first weeks did not extend beyond a few walks and talks, and that it was not until after Keats's return from his summer holiday that the acquaintance ripened into the close and delighted intimacy which we find subsisting by the autumn.
For part of August and September he had been away at Margate, apparently alone. A couple of rimed epistles addressed during this holiday to his brother George and to Cowden Clarke breathe just such a heightened joy of life and happiness of anticipation as would be natural in one who had lately felt the first glow of new and inspiriting personal sympathies. To George, besides the epistle, he addressed a pleasant sonnet on the wonders he has seen, the sea, the sunsets, and the world of poetic glories and mysteries vaguely evoked by them in his mind. The epistle to George is dated August: that to Cowden Clarke followed in September. In it he explains, in a well-conditioned and affectionate spirit of youthful modesty, why he has hitherto been shy of addressing any of his own attempts in verse to a friend so familiar with the work of the masters; and takes occasion, in a heartfelt passage of autobiography, to declare all he has owed to that friend's guidance and encouragement.
Thus have I thought; and days on days have flown Slowly, or rapidly--unwilling still For you to try my dull, unlearned quill. Nor should I now, but that I've known you long; That you first taught me all the sweets of song: The grand, the sweet, the terse, the free, the fine; What swell'd with pathos, and what right divine: Spenserian vowels that elope with ease, And float along like birds o'er summer seas; Miltonian storms, and more, Miltonian tenderness, Michael in arms, and more, meek Eve's fair slenderness.
