distance apart equal to the thickness of the wall 
about to be built, and concrete is dumped between 
them and rammed well into place. This process 
is continued all around the building and for all 
the cross partitions. After the walls are four or 
five feet high the boards are removed and replaced 
at a higher level and the process continued, until 
the desired height is reached. 
Reinforced I he process of building the floors and 
Concrete roofs is somewhat different. If these 
were built of plain concrete like the walls they

would have been heavier (because 
thicker) than is desirable. The 
walls, of course, are supported 
continuously throughout their en¬ 
tire length on the foundations. 
But the floors are supported con¬ 
tinuously only at their edges. To 
overcome this difficulty a method 
known as “reinforced concrete” 
has been devised and has proved 
so successful in application that 
entire buildings are now so built; 
outside walls, and all. This 
method of strengthening or rein¬ 
forcing the concrete is simplicity 
itself. Steel wire or thin rods, or 
still better steel frames are im¬ 
bedded in the concrete which enor¬ 
mously increases its resistance to 
bending pressures (such as a floor is 
subjected to) at a very slight rela¬ 
tive increase in the cost of erec¬ 
tion. This great increase in strength makes it 
possible to build the concrete thinner than would 
otherwise he possible, and it is for this reason that 
walls of high concrete buildings are built by the 
reinforced process. So applicable indeed is this 
principle to the construction of concrete beams 
and posts, that it has been successfully employed 
for the purpose of erecting high office buildings, 
in which the usual steel beams and columns are 
entirely replaced by concrete substitutes. 
Concrete I he latest application of this principle 
Pllin & is its employment for piling in founda¬ 
tions. Each pile is made of reinforced concrete and
