1. The Wall is either the Support of the Roof, or it is
Add here the wall for effect of Surface: Aesthetic in the enclosure of privacy: Or it excludes Hostility,
building where height does not properly admit of detached one of these Functions it must have: It is either
shafts, conf p 14. (2) Support or shelter, or defence.
In relation to these three functions; a wall is to be
considered either as - a. supporting vertical pressure,
Function a; Bearing of Vertical Pressure By general b. supporting lateral pressure, whether from an oblique
principle: that the best is that which is done with roof - or external violence; c as a veil, only;
least material, and it being evident, etc. Now if the function be to support Vertical pressure only;
the wall is {of course} best built where the given pressure is
supported with the smallest quantity of material. All
redundant material is an offence to the eye:
Now it is {evident or if not evident,} mathematically demonstrable
that the more solidly the materials are arranged,
the more weight they will bear: and also {that}
the most compact form in which they can be arranged is
that of a succession of cylindrical masses. This there-
fore is the best possible form in which vertical support
can be attained; and every truly noble building that
ever was built, or ever will be, consists {and must consist}
so far as {concerns} its vertical sup pressures, of some modification of it:
It is the Pillar support which has been
the source of grace and strength {in the buildings of all
great nations}, from the infancy of the world till now
and must be, so long as the laws of gravity remain unchanged.
