have taken for an example is fitted
/ with about twenty-four doors. There
/ fore $4,000 buildings will carry $500
doors Each door has two knobs, and
we get 100000 doorknobs, more than
I,OOO,OOO pounds OF dOOrknObs. or forty
carloads; 100000 sets of keys. Each
door IS about seven feet high, so we
/ have 100000 feet of doors or AIT
miles. With twenty-one feet of Ium-
Der in each door there will be used in
San Franchises new doors 1850. 900 feet
OF mflled lumber. or 1921 miles
The same sort Of building that
swings twenty-four doors will absorb
about fifty kegs of nails. so the re-
building city will use in a few years
100000 kegs of nails l started out
to count the number of nails in a key.
but after getting up to a thousand de-
cided that the effort was superhuous
began to ponder on the humber OF
blows that would drive so many nails
and Immediately perceived a sensation
of paralysis and pain in my right arm
Then L recalled the sufferings of early
married life. when. as an amateur T
hammered down carpets
Every building has to be plastered,
and the average amount of plaster
slapped on the walls is about 5000 yards
to g structure. Fifteen thousand struc-
lures would require the services of the
army OF plaStererS necessary to slap on
100000 yards. Ponder on the boom
there is going to be in the lime indus
try and the millions of yards OF sand
that will be mixed with it. A good sand
bank in San Francisco is going to be
mine.
The window glass manufacturers will
reap a rich harvest with about $500
square feet of windows to a building.
Multiplying by the conservative 5000.
1t will be seen that San Francisco will
provide market for $4,000 600 square
feet OF glass AS there are 1.742.336
square feet in a square mile, about
twenty square miles of glass will go
into. the windows of the greater city.
This is almost enough glass TO cover a
township. which is thirty-six square
miles. 1t would blanket an area five
times as great as the burned district
and provide a vitreous carpet for all OF
New York's Manhattan Island.
Fully 1900. 900 tons of steel and cast
iron will help to stiffen and grid up the
new structures of the city. as vastly
more of these metals is used IN mod
ern than was in former construction.
Eleven hundred millions, or LOO. oG0.-
900 pounds.
That" said a steel man who had been
racing a pen over a pad for an hour
figuring up. will be going some. II will
be going some for us and for hundreds
of other manufacturers who make cast
iron beams. rods or structural steel.
Just think Of the army OF blacksmiths
that would have been put on the job In
the olden days, and how the forges
would have rung with the clangor OF
ten thousand anvils OF course. now
we have mammoth labor-savinE and
Carnegie making machines to do the
greater part of the work for US"
II all this steel and iron the new city
is going to use were welded into armor
OF the sort worn by medieval warriors
there would be coats OF mail. visored
helmets. clanking greaves; in fact. tho
army Of so. zoo, 900 men-more armored
warriors than fought in all Europe's
wars in dark or brighter ages, more
warriors than fell in battle in all the
famous wars of the world.
