392 COMPARATIVE ARCHITECTURE. sculpture, tracery, and panelling, and bear a similarity and regularity in position which are marked features in these large buildings. D. Roofs. — In domestic work roofs have steep pitches, and are ither hipped (No. 169) or ended by crow-stepped and traceried gables of picturesque outline. Numerous turrets, and bold chimney stacks, combine with the tiers of dormers to complete the rich profusion of the walls below. E. Columns. — The use of round pillars in the nave, instead of clustered piers, is well exemplified at S. Gudule, Brussels (No. 167 B, c, d). a peculiar feature is noticeable in some town hall arcades, where a column is omitted by hanging up any two arches by means of a long keystone from a concealed arch, as at Liege. F. Mouldings.- — Coarse profusion is characteristic of Belgian Gothic, possessing neither the vigour of French, nor the grace of English, mouldings. G. Ornament. — In S. Waudru, at Mons, blue stone is com- bined with a red brick filling-in of the vault, in a scheme of permanent decoration, and S. Jacques at Liege is fully decorated with paintings of a rather later date. 5. REFERENCE BOOKS. Goetghebuer (P. J.). — " Choix des Monumens des Pays-Bas." Folio. Ghent, 1827.
