There was the same sort of antithetic mixture in Martin Poyser: he was of so excellent a disposition that he had been kinder and more respectful than ever to his old father since he had made a deed of gift of all his property, and no man judged his neighbours more charitably on all personal matters; but for a farmer, like Luke Britton, for example, whose fallows were not well cleaned, who didn't know the rudiments of hedging and ditching, and showed but a small share of judgment in the purchase of winter stock, Martin Poyser was as hard and implacable as the north-east wind.
