HISTORY OF SANITATION

awaiting the party at the foot of the steps are fully as
large and quite as comfortable as Venetian gondolas.
The great sewer, which is tunnel-like in dimensions,
being 16 feet high and 18 feet broad, is, on occasions of a
visit, lighted with lamps alternately red and blue, and as
these stretch away into the distance the effect is decidedly
striking.
Under ordinary circumstances, the sewage confines
itself to the center channel, but upon occasions rises above
the sidewalk on either hand. The central channel is about
io feet wide and 4 feet deep with a curved bottom, and a
walk on either side. The boats with their loads of visitors
are pulled by ropes in the hands of attendants who walk
along the sidewalks. On either side of the sewer may be
seen the large mains, carrying the city water supply, also
the telegraph cables.”
Reliable data concerning the construction of sewers
were not obtainable in the United States until long after
the close of the Civil War. In 1857, when Julius W. Adams
was commissioned to prepare plans for sewering the city
of Brooklyn, N. Y., which at that time covered an area of
20 square miles, a great proportion of which was suburban
territory, the engineering profession was wholly without
data of any kind to guide in proportioning sewers for the
drainage of cities and towns. The half century interven-
ing since that time, however, has seen the development of
sanitary engineering and witnessed the installation of sewer
system, rightly proportioned and properly designed, in
almost every city, town and village in the United States,
while text books on engineering contain all necessary data
for their design and construction. It must not be inferred
from the foregoing statement that sewers were unknown
in the United States prior to the construction of the
Brooklyn sewer system. There was one in Boston, for
example, which dated from the seventeenth century, while
the first comprehensive sewerage project was designed by
E. S. Chesbrough, for the city of Chicago in 1855.
There was no great activity in sewer building in this
