"Rusticated" applies to masonry work in which the joints are strongly emphasized. The dado has a plinth base of a height cor responding to the height of the column base, and a cap fourteen parts high. The bead and conge of the.bases continue around and above this plinth; the rusticated stones are alternately twenty-six and sixty-eight parts wide with sinkages of two parts.
177. The roof is pyramidal in form and is crowned by a pine apple, of which the detail is given at D in this plate, XXXII, and the balustrade shown at the left-hand side of the facade would be the rail of a terrace on the edge of which this pavilion is located. This terrace, although the pavilion does not communicate with it, would be accessible by flights of steps placed laterally. For this the student may exercise his own imagination, and draw out sepa rately at a smaller scale a plan giving his idea of the general arrangement.
178. The facade of a Doric temple is to be drawn by the student from the plan shown in Fig. 30. The measurements nec essary for the placing of the columns are here given, and further than this he is to supply their proper proportions and heights, as well as the necessary details, from the various drawings illustrat ing this order, which he has already studied. The four-columned portico on the front is crowned with a pediment, the proportions of which must be ascertained after the principle shown in Plates XXXII or XXXIII. This plate is to be drawn out with the border lines 20' X28° in size.
179. The proportions and general scheme for laying out this problem will be found in the illustration of the Ionic Portico, Plate XXXIII. The various details both for the exterior entabla ture and for the entablature inside the temple, as well as the archi traves for the entrance door, have already been given. The main facade or front elevation should be drawn to the center line which passes through the apex of the pediment and through the axis of the doorway. The section on this plate may be omitted, in which particular there will be a difference between this problem and the problem of the Ionic Order. In the plan it will be noticed that half has been shown with a pedestal, while the other half rests directly on a platform or "stylobate." It would be better to draw this order with a pedestal and to indicate by a dotted line the contour of the steps leading from the stylobate to the ground. The method of constructing the slope of the pediment has already been explained, and has also been shown on Plate XXXII E. This is essentially the same problem as that given under the Ionic Order, but the details and the proportions, it will be seen, are distinctly different.
180. The Ionic Temple, with portico, shown in Plate XXXIII is to be drawn at the same size as the last plate, 20' X28". These two drawings when finished should resemble each other, save that in preceding exercise the full facade of the temple is shown, while in this plate of the Ionic Order a half facade and section are to be combined as illustrated.
181. The exterior face of the wall is formed with rusticated joints, that is to say, the joints of the stones form triangular recesses or grooves as shown at C, Plate XXIX. This decorative scheme is at the same time a logical construction because, the angles of the stones being obtuse, the edges are less liable to be broken off.
182. This exercise is one of superposition and, as the same principle may be applied throughout the use of the other orders, it is believed that one drawing devoted to this subject will be amply sufficient. The student is required to reproduce the drawing shown in Fig. 23, at the size of 13' X18" and to complete in his drawing all the details of the mouldings, windows, doorways, etc., where the same are only blocked in upon this figure. The con siderations in regard to superposition, stated in the text in para graphs 116 to 132, must be carefully observed.
183. The subject of this study, Plate X, is the central part of the facade of an edifice; assume it is to be a.library or public building of a similar character. The Corinthian Order is raised on h series of pedestals. The interior level of the edifice is raised above the exterior ground level and is reached by a stair case which will prove to be part of this study. This staircase is in two parts, each part composed of two flights with an intermediate landing. The first flight has twelve risers up to the landing; the second has eight risers up to the top of a wide land ing which is placed before the entrance and on the axis of the edifice. A balustrade with two pedestals, on which might be placed statues or candelabras, surmounts the supporting wall of the land ing. This supporting wall is -finished on each side by a pillar on which is placed a vase, and is decorated with rusticated joints. The central part, corresponding to the balustrade, forms a projec tion; a niche decorated with a fountain and semi-circular basin would be practicable below this space. The entrance door of the edifice is in the form of an arch, covered with a pediment of the Ionic Order. The Corinthian columns forming the corners of the projection are coupled, that is to say, the space which separates them is less than the minimum of the regular intercolumniation.
