~of the Corinthian Order, to be 40 Minutes; there-
fore it ~fol1ows, That to have two Modillioz~

to have ~hrce Modilhions between, two Diameters,

 Cornice over Columns, is the fame as in the lonick
 Order~ therefore the Diftance of Compo]ite Columns
 and Pi~laflers are the fame as of lonick Columns
 and Pilafl~er~.
   The Manner of proportioning the feveral Or-
 ~de~s, and determining the proper Diftances they
 are to be .placed at, being thus explained; I fhall
 z~ow .prpceed to give fuch E~planation oF. the fol-
 1.iwii~ Plates, as will render the Bufinefs of every
 Deep eafy and de~lightful to every one, who has
 ~made I i~dUfaMafter of the precedent Orders.
     ~Plate XVI, XVII, XVIIIS, XIX, XX.
         of PIERS far GATES.
    t~o make thefe, and all other Defigns contain-
 44~ia1 ~ Work, eafy ~ the Underiff.anding of all
 ~ ~nd to enable fuch to work them,
 ~ required; I have to every De-
  gn a1~ize* Scales of Aliquot ?arta, (which never
 ~AS done bei'ore by any Matter) whereby, having
  oniy the Height of any Work to be made
 ~(whi4i in all Cafes mutt be given;) the Whole
  ~ay fr performed with the utmoit Exa~tnefs as
    As for Exawpk; La it he required to proportion
  the Pier G, Plate XVI. to any gk.~'en Height.
    Divide the given Height, (fuppo~ ten ~Feer)
  isto four equal Parts (as fignified by the Scale on
  its Left Sk~e) give two thirds of the loweft I
  Part to the Height of the Subplinth G, and two
  thirds of ihe other third Parr, to the Height of
the Plinth, Torus, and Fillet.  Divide the upper
fourth Part, in 3 Parts; and the upper i Part
iI*~~f ~n ~ ?ares; of which, ~ 'the
2 Parts to the Height of the ~itai         v~1~
Members are above defcribed at large by Fig. B.
By the dotted Arch of a Quadrant in the Sub-
plin*h G, it is evident, that the Breadth of the
middle pi'oje&ing Part of the Pier, is equal to
the Height of the Subplinth; which Breadth di-
vide in 4, and give i to th~ Proje&ion of each
  The Height of the Subplinth ~of ~the Pine Ap-
ple on the Capital, 'i~ one-Part and one Thirvi, as
fignified by the dotted Semicircle:   And     the
Height of the Pine Apple and its Pedeftal is de-
-termined by the Jnrerfeaioa of Arches deiribed
on the ~extren~ Points of the Capital's Projec-
don, and which beir~g divided in 3 Parts, and
the lower i in 3, &c. give to every particular
Member, its refpe&ive Height, as exhibited. The
 Proje&ion of the ?hinth to ~the P.e~.leftal of the Pine
 Apple, is two thirds of the Projeaion of the mid-
 dle Part of the Pier.
    Now the young Student is to obfervc, that as
 the conftituent Parts of all the Defigna in this
 Work, are adjufted in the very fame Manner as
 thofe of theabove Example ; which, it is manifeft,
 are no fooner' feen but underifood ~ it is therefore
 evident, that to fay any Thing further rdatii~g
 thereto, is needlefs.
    Thef~ five Plates contain eighteen Defigos of
 Piers for Gates at Entrances into Gardens, Ave-
 nues, Courts, Palaces, &~. whkh may be built
 either of Stone or Brick, or of both, incermix'd,
 at the Plealiire of thoi~ for whom they may be
      U ATE S for Entrances iniG Palaces, &c..
    Five Defigna. for Gates, of which the firft,
 fecond, third, and fourth, are according to the
 Tufean, Derick, Lonick and Corinthian Orders; whofe
 refpe&ive Impofts and Architraves of their Arches
 are defcribed at large, and proportioned by AM-
  quot Parts, at the BottQm of each Defign     as
  likewife is the Impoft and Architrave ro~rhc Gate,
  Plate XXV. made for an Entrance to~ the Houfe
  of a private Gentleman, &c.
