Example "63, fig. 63, shews the method of proportioning the mouldings of the 4 Tuscan pedestal.' Every pedestal is divided into three parts,—the 'base,' as ab; 4 die,' bc; and the 4 cornice,' cd. In the figure given the whole height of the pedestal is four modules. In order to keep our sketches within the limits of the page, we take the proportions from a scale, the divisions of which are only half the size of those in fig. t62. At a draw a line of indefinite length, and at right angles to it a line ab; make ab equal to 2 diameters, or 4 modules, ac equal 26 parts, cd equal 4 parts, de equal 8. Make the 4 die' en equal 2 modules 4 parts; make bf equal 3 parts,equal 8, gh equal 2, gn equal 4. The projections of the mould-

•ngs are all set out from the central line a b. From a with 53 parts lay off to t, «, and from these draw lines meeting that drawn from c; make dm fig. 68.

equal 51 parts, or set back the line md 2 parts from the end of line c; make eo equal 41£, and the die equal 40 parts; make 611 equal 53 parts; make gs equal 50J, and 8t equal 7, and nv equal eo.

Example 64, fig. 64, shews the \ 1 base' of the Tuscan order. Draw the centre-line cdy put the 4 plinth1 ab, making cb equal 40 parts, and ce equal 15 ; make the ' torus' moulding in height equal 12 J parts. The centre m of the circular termination is found in the line f. Make the fillet h equal parts,v and its projection from centre-line equal 33|, or nearly 34 parts. To describe the 1 apophygee,' by which the lines of shaft are connected with the base, see work on fig. 64.

Practical Geometry, where also the various forms of mouldings met with in the Orders may be found described, and the methods of delineating them.

Example 65, fig. 65, is the Tuscan « capital,* drawn to the same scale as the others. Draw cd7 ab ait right angles; make ca, cb equal 22£ parts, or a b equal 45 ; make the fillet of the astragal en equal 24y parts, or nn equal 49 parts. Make g h equal 27 ; gi, the 1 neck/ equal ab or 45 parts, and the fillet m above the neck equal en. Make the diameter of 1 abacus' rio equal 60 parts, or 1 diameter. These are the projections ; the heights are as follows:—The fillet «/equal 2 parts; fg equal 4; g m equal 8£; the fillet above this the quarter-round mn' equal 10; the abacus or plinth no equal 10. The quarter-round begins at 1 part back from 8.

Example 66, fig. 66, is an elevation of the Tuscan entablature consists of three parts,—the 1 architrave the 1 cornice' CD. Draw the line bd representing the centre-line of column, fig. 65.
