est bond known to masonry construc-
tion--a header bond every seven in
ches Ia the vertical. The heavier the
bond In such a wall, the greater it's
lateral strength. A test of single
blocks, n days old, IL inches by "a
inches, for 12-inch wall. set on edge
on plank and unsupported in any
way, was made at the Allis-C Chalmers
works, Milwaukee, showing a crushing
strength of $500 pounds per square
inch. The blocks for this test were
selected at random by a committee
from those made for the National
Electric Co. milwaukee, Office build
ing.
In the two-piece wall, where a block
is to be faced, the mold is filed with
one-to-seveu or one-to-ten mixture
OF coarse concrete, q quarter Of an inch
is ralSed out of the top of the mold
and this space is filed with face mat
ter mixed one to two and a half fine
sand and cement The entire mass is
then compressed at once by the ma
chine with 100000 pounds pressure
giving a hard and beautiful face Of
great density, which will never crack
or peel off, as is the case witch faces
troweled on after the block is made
The width OF wall made is from 5&
inches up as high as so feet. The air
space provided in this two-piece wall
is a so per cent space, increasing with
greater width of walls, the air chamber
in the wall is horizontal as we'll as
vertical and completely unbroken. The
average weight of these blocks is from
"a TO so pounds, depending upon the
width Of the wall easily handled by one
man.
Under this two-piece system, two
men at the press (the mixture is au-
tomatically supplied) will make and
load on cars or racks conveniently plac-
ed, 1900 blocks in ten hours. This
daily output in blocks 9x24 inches, is
equivalent to 800 square feet of wall,
enough for the walls of cottage 20x25
feet, 10 feet high.
When the blocks are taken from the
press they are loaded onto cars, which
hold ninety six blocks each. These cars
are run into a shed and the blocks kept
moist for SO hours. At the North Da-
kota Engineering & Contracting Cos.
plant, live stream curing rooms are
used. Twenty-four to forty eight hours
in this live steam room and forty
eight hours in the air prepares the
blocks for the wall.
1T is said that no engineer or. con-
tractor has ever found any fault with
this system. The correct principles
upon which 1t is based have gained for
1t immediate and enduring success. 1t
Is scientific method of producing
strong, dense and slightly blocks and
"a l,rf1I
structed that engineers cannot criti-
cise-so beautiful that architects APP
prove.
1t is enlightening and gratifying to
know that Fargo has a plant which
represents such remarkable achieve
ments in SO great an industry. It will
be well worth the time of every man,
woman and child TO pay this plant a i
visit and carefully inspect it's methods
of manufacturing and handling cement
blocks Everybody is welcome and will
be personally conducted about the
premises.
Out of the hundreds of buildings
erected by the Ferguson system, few
of the most important ones are named |

portant Fargo structures will soon be |
constructed Of the age proof, fire. proof |
