WHARF CONSTRUCTION, SYDNEY HARBOUR. XLIII. 
including land ties, and Monier plates runs from £4 to £6 
per linear foot of wall, according to the depth of the water 
and other conditions. The Monier plates are made in 
several lengths to suit the various heights of the wharves. 
The lengths range from 9 feet to 12 feet 6 inches. They 
are 2 feet wide and 5 inches thick, being spared out in 
panels at the back to save weight. 
Where the Monier plating occurs under a wharf, or jetty, 
they are bolted to horizontal walings, with 14 inch gal- 
vanized coach screws about 10 inches long, the attachment 
being thus a very simple process. Where the Monier 
plating stands as the exposed face of a wall, as for instance 
between two jetties, T-headed plates are used. They are 
simply dropped in between double walings and trim up 
against vertical wooden fenders, every 10 feet, so that 
they are protected both vertically and horizontally from 
being chafed by vessels. In one instance, at the foot of 
Market Street, where rock was met with at a reasonable 
depth, instead of using Monier-faced tupentine piles, 
Monier needles 27 feet long and 18 inches on the exposed 
face, were stepped into the rock below, and held back at 
the upper ends by walings and land ties. 
It may be interesting to note that the total length of 
berthing space in Sydney, under the control of the Harbour 
Trust Commissioners, from Woolloomooloo to Darling 
Island, amounts to 39,236 linear feet, and that the shed 
storage capacity in connection with these wharves is 
equal to 373,200 tons. This shows a large amount of work 
done up to the present, but much important and interesting 
work will have to be carried out each year for many years 
to come, in order to keep the berthing and shed accomo- 
dation in line with the ever increasing tonnage which may 
be expected to visit our port.
