we have a hard tenacious soil,
which probably would obviate
the necessity of any protection
to the works even in the shape
of the fall above proposed, such
an arrangement would never-
-theless place the works in perfect
safety. In high floods in the
Seyngoor, the water rises to a
depth of between 6 and 7 feet;
on these occasions there would
be back water in the escape
channel up to the Rajbuha
Superpassage Bridge floorings.
The escape channel has
been excavated on a rectangu-
-lar width of 25 feet with
slopes equal to the depth, the
slope of a bed being equal to
1 1/2 foot per mile: this it will be
understood from what has been
said before, is a mere economical
arrangement, the true deposition
of permanent slope being formed
(vide Rule 5) on the calculations
above figured.
Kunkur has been largely
used in the works at Gihror, as
a building material, and in
the difficulty which has attend-
-ed on brick making, has been
of great service in expediting
the completion of the work.
The [proportions of, struck through] ingredient
used in the cements is
Pure Kunkur Lime
The total quantity of masonry
and the rates of the work are:
22676.2 cubic feet at
an average of
Rs 12..13..10 perm 100 cub feet
