esEfclSlly as there have been SO many and such
varied theories from time TO time as to the canal
nuisance and The drainage question. TIE entire
length OF sewer TO be contracted for is about
t'@S rect, DIVIDED into sections which gradually
increase in dimensions towards the mouth or
The sewer, which discharges into the canal at
l.th street The size Of the sewer on TIE inside
AT tth street is five feet six inches wide ty three
fCet zire inches IL height, and is increased, sec
ton by section, towards its mouth, which Is
twelve feet six Inches wide by seven fee, three
inches in height, and is capable OF earring OF
all the drainage which will empty iato j..
THE WORK
Is to be let 10 contractors in sections, and in
cruces excavation, furnishing all materials
and %ork OF construction, to the entire sgtiSfac-

joints.
IArERALs
are TO be built to intersect with this sewer at all
points where II crosses the sewers already con-
structed, and at other points where required to
meet the general plan of sewerage iUT the CITY
These IateTals are TO be OF the proper sizes
whether OF brick or drain pipe. and are to extend
10 such distance from the main sewer as NAV he
des grated by the engineer. Manhoes are to be
constructed of the usual size. and to be at a dis

proper grade, and covered by suitable caps
Tht mortar used in this work is TO be compos-
cd Of the best quality hydraulic cement and clear
