Fire Fighting and Telephoning

Both Need Team Work, Modern Tools
and an Ever Ready Plant, Everywhere

Twenty men with twenty buckets can put out a small fire if each man works by himself.

If twenty men form a line and pass the buckets
from hand to hand, they can put out a larger fire.
But the same twenty men on the brakes of a
“hand tub” can force a continuous stream of
water through a pipe so fast that the bucket
brigade seems futile by comparison.
The modern firefighter has gone away beyond
the “hand tub.” Mechanics build a steam fire
engine, miners dig coal to feed it, workmen build
reservoirs and lay pipes so that each nozzleman
and engineer is worth a score of the old-
fashioned firefighters.

The big tasks of today require not only team
work but also modern tools and a vast system
of supply and distribution.
The Bell telephone system is an example of
co-operation between 75,000 stockholders,
120,000 employees and six million subscribers.
But to team work is added an up-to-date plant.
Years of time and hundreds of millions of money
have been put into the tools of the trade; into the
building of a nation-wide network of lines; into
the training of men and the working out of meth-
ods. The result is the Bell system of today-a
union of men, money and machinery, to provide
universal telephone service for ninety million
people.
