the figure flrews. Again, divide a diameter into four, as that
diftinguifhed by the writing in the figure, and take three of
thofe parts for the perpendicular height of the cornice : at this
height draw a parallel line at pleafure fufficient for the whole
length of the pediment, as the upper line with the numbers.
Then take the perpendicular height of the cornice, and place
it from the outfide line of the fhaft on the line continued out
from the under edge of the cornice, which will determine its
projection, as is eafily feen by the level fcale line h. Raife a
perpendicular line from the whole projection, as g, till it cut
the upper parallel line; then will this line ferve as a fcale for
the heights of each member in the cornice, the proportions of
which are eafily feen by the aliquot parts on the fcales; but if
not rightly underltood, the reader may fufpend his judgment
till the Tufcan order is defcribed.
Divide the upper parallel line, which is equal to one-halt
of the whole length, into nine equal parts, and give four of
thefe for the pitch of the pediment, as the figures i, 2, 3, 4,
ilrew. Draw then a right line from 4 to the utmoft projection
of the level cornice, and proceed to draw each member of the
level cornice, as the fcale lines direCt.
Note, The two upper lines, containing the nine divifions,
reprefent the upper fillet of the level cyma-reCta.
