“Around the docks and river
quays there are single-storey transit-
sheds covering an area of 45,000
square yards. A cross-section of one
recently erected is shown in fig. 373.
It is 300 feet in length by 120 feet in
breadth, in two roof span-s of 60 feet,
and the height from ground level to
the eaves is 13 feet 9 inches. The
walls are of brick, with ashlar quoins
and tabling, and there is a row of
cast-iron columns along the centre
of the shed supporting the roof, and
a similar row on the river front, which
is closed in with wooden sliding doors.
The roof covering is of slate, and the
principals and girders are of mild
steel. The shed is floored with grano-
lithic pavement, consisting of a 4-inch
layer of broken stone, upon which is
laid 4 inches of Portland-cement con-
crète, covered with 2 inches of grano-
lithic, composed of clean granite chips
and Portland cement, gauged 1 to 1.
The cost is 5s. per square yard, and
this flooring is found very satisfactory
for both light and heavy traffic. The
total cost of the buildings averages
3s. per square foot of ground covered.
A row of single-storey warehouses has
been built opposite the transit-sheds,
constructed of iron with party walls
of rubble masonry. They cost 0-97d.

square foot of ground covered. In
addition, there is a five-floor ware-
house at Victoria Dock, witli a
