Comprising Reports of Select Farms; Outlines of Flemish Husbandry; Useful and Ornamental Planting; Road-Making; Cottage Economy. (Library of Useful Knowledge), London: Baldwin and Cradock, […], pages 17–18:

     The year-olds are kept in the field all winter, in the same way as the calves, but get straw instead of hay, till near Christmas. They, of course, require more hay than the calves; but much hay is saved by their eating up the rough grass, left by the cows that pastured the ground in the summer, the calves and the year-olds being kept, during winter, in the old pasture-lands, never upon the poor, wet, thin clay.
