Statistics about agricultural laborers were the substance; any real ditcher, plowman or farmer's boy, was the shadow. Though he had never noticed it himself, he had a great reluctance, in his work, ever to use words as 'man' or 'woman.' He preferred to write about 'vocational groups,' 'elements,' 'classes' and 'populations:' for, in his own way, he believed as firmly as any mystic in the superior reality of the things that are not seen.
