Architecture

Rural architecture has been greatly improved within the last quarter of a century. Much greater attention is now paid to the structure of garden and farm buildings, and the domestic comfort of those employed in rural labour. There is of consequence an elevation of taste, and conduct, and beneficial results to all concerned. In England, Loudon has laboured to this end with great success, and his Encyclopaedia of Villa and Cottage Architecture, is a monument to his industry and indomitable energy. Downing, in this country, has followed the path so plainly marked by Loudon, and produced a volume, which cannot but refine the taste, and correct much that offends the eye.
