are large square paviliuns surmounied
by domes which mark the four
corners Of the bullding and are lighted
by large archcd windows extending
through the galleries
between the main entrance and the
pavilions are richly decorated arcades
forming an open loggia ON the ground
floor aud n deeply recessed promenade
ON the gallery fonr level which COM
mands n fine view Of the k.3es and
islands b. the northward and the great
central court on The south These COW
erred promenades are each IS feet wide
and $50 feet long, and from them n
had access o. the building At numerous
points These loggias on the first hoor
are faced with marbles of different
kinds and hucs which will be consid-
cred a. part Of the mining exhibit and
80 constructed as To have marketable
value at the close Of the exposition.
The loggia ceiling viii be heavily cof-
fcrcd and richly decorated In plaster
and color. The ornamrntation Is
maSscd a; the prominent points Of the
facade. The exterior presents u mass
i've though graceful appearance.
The main fronts arr G5 feet high from
ground to top Of cornice, ana the main
central entrances are % feet TO apex Of
pedimcnt. The long sides 81 the build
ing are treated In simpler manner
than the main fronts Large segmcntal
windows extend through the galleries
I and nre placed between the broad piers,
afrording aR abundance Of light 10 the
space beneath the galleries. The two
storicd portion Of the building. OF
which the gallery forms the upper part,
extends entirely around the structure
and is 90 feet wide. This portion Is
built OF wood and iron combined.
The great interior space thus inclosed
is one story high, $50 feet long and $50
/ feet wide, with an extreme height OF
| 100 feet at center and a. feet at sides
and Is spauned by steel cantilever rooi
trusses supported on steel columns
placed 65 feet apart longitudinally and
! ll5 feet and 81 feet q inches trans
vcrscly, thus leaving clear space in CEN
ter of building $50 feet long and lll
feet wide. with two side divisions, each
81 feet q inches wide and $50 feet long,
leaving the central space incumbercd
with only Ii supporting steel posts.
The cantilcvcrs are of pin connection
To facilitate erection. The inner and
higher ends of the cantilcvers are Al
feet apart and the space between them
Is suanned by riveted steel trusses with
an elliptical lower chord.
These trusses are designed so rs tn
form a clcrestory II feet high, with
vertical sash extending the entire
length Of central space-G30 feet; said
space terminating at each end with d
great glass gable setting back GO feet
from front ends OF building. The wide
spacings Of the cantilever necessitatcd
an extensive system of longitudinal
perlines Of the riveted lattice type. A
great portion of the roof Is covered
with glass.
II may bc of interest to state that the
cantilever system as applied TO roof;
has not been used heretofore on So
large scale and that the Mines build
ing Is the only one OF the exposition
group, excepting the large domcs, thai
has steel roof trusses. The foundation
of the building is built of wood laid be
low frost in the sand A layer of three
inch plank is first put down and ther
crossed with heavy timbers which re
ceive the posts, each supporting poin
being broadened to suit the load, ad
hitting not TO exceed two tons pressur,
per square foot on the earth. The ex
terror of this building, like all th'
,. Others, will be made of 'staff, simila
To that used in facing the recent Pari
exposition buildings.
