Economy and Guiczness Of preparation are not
The smallest considerations in favor OF this in

place where the building is being run up The
cement IS formed in variable proportions rom
a mixture Of cement with sand and gravel or
small stones It is prepared either by hand or
by machine in the works while the different
parts OF the iron OF steel bractng are being put
n position. These are then surrounded by
wooden moulds OF bOxiugs. in-o which the cs-
ment is run and kept there until completely set

The construction needs only ordinary rna-

Buildings OF sJeeled cement are q rhe highest
