It would be a more serious complaint that Pope, who can thus admit anachronisms as daring as any of those which provoked Johnson in Lycidas, shows none of that exquisite feeling for rural scenery which is one of the superlative charms of Milton's early poems.
Though country-bred, he talks about country sights and sounds as if he had been brought up at Christ's Hospital, and read of them only in Virgil.

Many corrections show how carefully Pope had elaborated these early lines, and by what patient toil he was acquiring the peculiar qualities of style in which he was to become pre-eminent.

We may agree with Johnson that Pope performing upon a pastoral pipe is rather a ludicrous person, but for mere practice even nonsense verses have been found useful.
The young gentleman was soon to give a far more characteristic specimen of his peculiar powers.
