net, is very characteristic of this style at its best period, about the middle of the Fourteenth Century. Square-headed windows are very common. Windows in towers are usually different from those in other parts of the church. In the upper story, where the bells are, there is no glass; in some parts of the country there is pierced stonework for keeping out the birds, but more usually they are of wood only. These are called sound-holes. Clerestory windows of this style are often small, and either circular with quatrefoil cusps, or trefoils or quatrefoils; or the spherical triangle with cusps, which forms an elegant window. The clever manner in which these windows are splayed within and especially below, to throw down the light, should be noticed.”--(J. H. P.) The large rose-window, so conspicuous a feature on the Continent, is rarely seen in England. When it does occur it is usually found in the transept ends. The East Front generally consists of one large window at the end of the choir, flanked by tall buttresses. A smaller buttress appears at the end of each aisle. The arrangement of the West Front is the same, with a doorway beneath the central window. The towers of the Decorated style are usually placed at the west end and are, as a rule, similar to the Early English. The spires differ slightly from those of the Early English, except that there are generally more spire-lights and small windows at the bases and sides of the spire. Lichfield Cathedral is one of the best examples of the exterior of a perfect church of the Decorated style. Its three spires are perfect.
