Palladio, hish authority, says iha' 'hs

face a distance equal 10 one siiih OF 'he
height Of the elikee. In the city ot tau

foundation is made by partially hll'ns q
trench several feet ih depth With concrete
or pebble mortar, as soon a. lhn oees~e'

lesson to the peopl. OF Dallas county.
allude 10 the Court House built only rev
wears ayp Of bricks so utterly worihlsh
that the building was actually crushed by
Its own weight. Now, one OF the easiest
experiments imaginable Is TO ascertain
the Precise amount Of weight That WhI
crush a brick; and knowing the weight o'
A brick, we can tell exactly how many eaeh
one will sustain before being crushed Hnd
when we equal or exceed tliis amount Nc

terwards. A builder should know "hat
newer will crush a cubical block OF every
material he makes use Of; II he does not
know this he is incompetent and should
not be eurluyud lie should also expert
mrnt much with his lime; no two lime
stones produce the same quality OF lime
IL is generally believed that the hardest
rock produces the best lime but VIC are as.
sured that as good lime is made In england
from chalk Ms any limestone what,Ver'-
Many experiments should be made IN COM
bininr lime and sand, and ascertaining
the best proportions for durable cement,
Then again In building up walls, particu,
larly OF cut stone, no single stone shouiu
be supported in any part by weuges.-
Some OF the most renowned edihces coh-
structed in modern times have failed from
this defect. This VIC are assured by VI
Sgan1in was the case with tho French
Pantheon, which had in part to be taken
down and reconstructed. To dig a trench
two or three feet deep and throw IN loose
H,t stones without mortar for foundation,
especially for building of cut stone, We
should regard a. certainly defective IN .
country like this where both lime ana
sand nrc extremely abundant. ] certainly
think that the authorities who contract for
expensive public buildings should Eho"
what they are about. and IL they are them
selves ignorant Of what is requisite to &C.
cure the faithful execution Of . substan'
tial work they should employ skillful Ar
chitect to observe the progressive execu'
of the work, and to determine II IL ha'
been completed according to contract. La
case the contract permits the erection o'
an unsubstantial building upon an inse
cure : foundation, then the authorities
should be held personally responsible tc
the people for another instance OF superia
tive folly.
The writer does not wish to be under
stood as an endorser of an expensive edi
flee at this time, when taxation is 80 higf

lie considers that this Court House h.'
been saddled upon US without our knowl
edge or consent, and rs he sees no way Of
avoiding the expense he only wishes th'
work may be SO executed that we 'shal

think that a wooden structure would nave
been quite sufficient for several years u
come until the people should have become
more able to build fine Court House.
