the real work OF raising the sky line
OF New York will be done by the large
buildings that are growing up to these
record heights. 1t IL only fair that
these huge, though not SO tall build
ings, should receive recognition.
The largest office building now In
course of construction is an annex to
the Whitehall building on Battery
Place. The original structure is only
twenty stories high. but the Annex is
to consist of thirty-one stories, and
Will rise to height of AIS feet from
the curb. While this is about rs feet
less than the extreme height of the
City Investing building, 1t represents
larger rental capacity when com.
bined with the old building. the office
space In the two being $4,000 square
feet. or more than in any other build
ing in the world. The Annex is built
on a plot of b1.5l5 square feet, and
the total cubical capacity of the build.
ing, exclusive of the foundations, will
be 100000 cubic feet.
Before commencing the actual con.
struction of the bailding, it was nee,
essary to excavate 1900 cubic yards
OF earth This is equivalent to dig
ging narrow trench eighteen feet
wide and six feet deep all the way
from the Battery to Madison Square.
In order to convey an adequate idea
OF the tremendous proportions of this
building, the writer has dissected the
structure and assembled the principal
materials. The structural steel work.
representing 1900 tons, has been
built up into a single girder of stand.
ara proportions 10 feet square, the
metal being correspondingly heavy.
ana this extends to a height of 3Os
feet. The girder compares fayorably
with the Madison Square tower. In
constructing the walls of the building
seven and half million common brick
Will be used, and these, If built UP
proportions, would completely over.
shadow Madison Square garden. In
addition to the common brick. 900 .OO0
face brick will be required In the build.
ing as well as 5000 tons of ornamental
terra Gotta and the latter nodded into
single capital would occupy the d..
mansions given in the illustration
Within the building there will be $50.
900 square feet of partition tile and
10000 square feet of column cover.
Ing, $4,000 barrels of Portland cement
VIII be used. The cinder fill for the
| floors will be about half a million
cubic feet, which. il put into n rural
sidewalk of standard dimensions would
reach nearly all the way from New
YORK to Philadelphia. 1t is astonish.
ing how much glass Is required In the
building. If made into a single sheet
1t would cover 10000 square feet. or
more than an acre and half. Even
such a thing as the window weights is
an enormous item, as will be eyidenc.
ell by comparing the huge window
weight in the illustration with the
man shown at the right hand side.
While modern office buildings are con.
structed of fire proof materials. n Ger.
tam amount of wood is absolutely
necessary. For the floors alone of the
whitehall Annex, 100000 board feet
or yellow pine will be required, while
for the base molding. 10000 feet will
be used.

feet OF radiator surface will be fur
nished and II single radiator were
made to provide this amount of radiat.

level with the roof of the Madison
Square garden. The boiler equipment

electric fixtures, with 65 miles of con.
Outs and wiring. Ten miles OF plumb.

Few of the Items required In the
construction and equipment of the
building they suffice to show that a

zeal or interest quite apart from it's
