sunk July 25 and the first column was

was fully under way. it rose like magic

ten days.
A GIGANTIC STEEL CAGE
This building is of what is known as
steel cage construction. that is. there is a
steel framework or skeleton that is COM
/ plete and Independent of itself carries its
I own weight. the floor loads, roof and all
wind pressures and other stories, the
] whole being supported entirely by the col
umns and their braces which transmit the
resulting pressure loads to the founda-
/ tions. Instead of the floors and roof being
partly carried by the walls as formerly.
the walls themselves are carried on special
gfrders that are attached to the columns
at every story. each supporting a zone or
belt of masonry that merely serves as an
ornamental screen to exclude the weather.
Each column section was about 30 feet or
two stories long. the lower ones weighing
over 5000 pounds each. Columns. Orders,
beams. braces and all other steel work
was delivered on trucks and Immediately
hoisted from the street, and set in the
required position by two long derrick
booms that Were lifted from story to
story as the work progressed and always
operated by stationary hosting engines

any falling articles and for a working
platform. on which the stonecutters
