چمن خانم دوزبری در دست کسانی بود که آن را دوست داشتنی ترین در ساری می شناختند. شمشیر صاف و فنری که جلوی خانه کشیده شده بود همه از یک شبدر زرد کوچک تشکیل شده بود. زیر پا مانند توده ای روی مخمل می داد. نگاه یکی از آن به فواصل میانی بیپایان ویلد پوشیده از بلوط، با خط آبی نامشخص ساوث داونز در پسزمینه بود. پشت خط الراس، تپههای بلند و کم ارتفاع از سنگ آهک پالودینا در طبقات متوالی خودنمایی میکردند، که هرکدام توسط مه مه آلودی که تا ابد بر فراز درههای پر درخت میچرخد، به سمت همسایهاش پرتاب میشدند. تا این که، در میان همه آنها پرسه می زد، سرانجام چشم بر روی ضایعات رشد حلقه شانتونبری، که به صورت کم رنگ در دورترین خط افق مداد شده بود، قرار گرفت. شبحهای سایهدار ارتفاعات کمروی لبه شرق و غرب را قاب میکردند. آلن مریک آن را با رضایت عمیق نوشید. پس از آن طرحهای تند و واضح ایتالیایی، سخت مانند لاجورد، ابهام مرموز، وسوسهانگیز بودن مناظر انگلیسی ما به تخیل میپردازد. و آلن از یک تور اوایل تابستان در میان جامدات پروژینسکی آپنین آمبریا تازه خانه بود. او در حالی که به طرف سرگرم کننده اش برگشت گفت: «بالاخره چقدر همه چیز زیباست. در ایتالیا، پسزمینهای است که نقاش به آن میپردازد؛ در انگلستان، ما بیشتر به فاصلهی میانی نگاه میکنیم.
Mrs. Dewsbury's lawn was held by those who knew it the loveliest in Surrey. The smooth and springy sward that stretched in front of the house was all composed of a tiny yellow clover. It gave beneath the foot like the pile on velvet. One's gaze looked forth from it upon the endless middle distances of the oak-clad Weald, with the uncertain blue line of the South Downs in the background. Ridge behind ridge, the long, low hills of paludina limestone stood out in successive tiers, each thrown up against its neighbor by the misty haze that broods eternally over the wooded valley; till, roaming across them all, the eye rested at last on the rearing scarp of Chanctonbury Ring, faintly pencilled on the furthest skyline. Shadowy phantoms of dim heights framed the verge to east and west. Alan Merrick drank it in with profound satisfaction. After those sharp and clear-cut Italian outlines, hard as lapis lazuli, the mysterious vagueness, the pregnant suggestiveness, of our English scenery strikes the imagination; and Alan was fresh home from an early summer tour among the Peruginesque solidities of the Umbrian Apennines. "How beautiful it all is, after all," he said, turning to his entertainer. "In Italy 'tis the background the painter dwells upon; in England, we look rather at the middle distance."
