I have shown by a specimen how Brown, working from his diaries of the tour, expatiates on his and his companion's enthusiasm over the romantic scenes they visited. Keats in his own letters says comparatively little about the scenery, and that quite simply and quietly, not at all with the descriptive enthusiasm of the picturesque tourist: hardly indeed with so much of that quality as the sedate and fastidious Gray had shown in his itineraries fifty years before. Partly, no doubt, a certain instinctive reticence, a restraining touch of the Greek [Greek: aidios], keeps him from fluent words on the beauties that most deeply moved him: his way rather is to let them work silently in his being until at the right moment, if the right moment comes, their essence and vital power shall distil themselves for him into a phrase of poetry. Partly, also, the truth is that an intensely active, intuitive genius for nature like his hardly needs the stimulus of nature's beauties for long or at their highest power, but on a minimum of experience can summon up and multiply for itself spirit sunsets, and glories of dream lake and mountain, richer and more varied than the mere receptive lover of scenery can witness and register in memory during a lifetime of travel and pursuit. In this respect Keats's letters written on his northern tour seem more essentially the letters of a poet than Shelley's from Switzerland and Italy. Shelley pours out long, set, detailed descriptions, written as any cultivated and enthusiastic observer visiting such scenes for the first time might write, only with more beauty and resource of language, rather than as one made by imagination a born partner and co-creator with nature herself, free by birthright of her glories and knowing them all, as it were, beforehand. Keats's way of telling about his travels is quite familiar and unstrained. Here is a paragraph from his first letter to his brother Tom, written at Keswick after walking round Derwentwater and climbing Skiddaw:--
