of Hall's Brick Making Machines,
the advantages of which have
been explained under the
head of Materials. After lining
out the Brick fields, and fixing
the position for the kilns, the
Brick manufactories were con-
signed to the charge of the
Executive Officer of Materials
who deputed an European Over-
seer for their superintendence.
When the works had been
lined out, and excavators had
been placed upon them; [Mr., struck through] the
[Cogin's, struck through] first object was to dis-
cover in how far [?] might be
lowered, the spring water level,
by taking advantage of the
natural declivity upon which
the River ran, in carrying a
ditch or trench on a [?]
slope from the foundations on
a course corresponding with the
direction of the current. The
natural slope of the bed was
8 feet in a mile. [Mr. Login. struck through] It was
supposed that [he might, struck through] by
giving the bed of a trench a
declivity equal to 2 feet per
mile [reduce, struck through] the spring level
[^might be reduced] to at least 6 feet, and by these
means, [commence, struck through] the laying
of the foundations [^might be commenced], at an
equal depth below the water
level.
The accompanying sketch
shows in plan and section, the
drainage works that were executed
on the above principle, and which
during the whole of the operations,
performed their duty most ef-
ficiently. The spring water was
reduced
