enabling the rollers (with the exception of the last one) to be removed, and the pipe would be slowly lowered on to
the harbour bottom.
As pipe laying would be commenced in the centre of the harbour and be carried on towards both sides simultane-
ously, while one lighter was occupied in laying, the other could be loading a pipe section and getting into position
over the line.
When the pipe had been laid the anchor bloks, which so far had acted as alignment and position blocks, would be lifted and deposited over the flexible joints.
The end landings being laid on prepared foundations in fafily short lengths, and in comparatively shallow water, would not present any very considerable difficulty.
Close to the Kowloon Railway Sea Wall would be. situated a Valve House containing a stop valve, a washout valve, an air valve, an automatic slow closing valve with flow recording apparatus attached, and a bye pass with a meter for leakage testing purposes.
On the Hong Kong side there would be a full bore
washout valve, a stop valve, an air valve and a reflux
valve.
It is not considered necessary to allow for any method of washing out the pipe at its lowest point on the harbour bottom, as a full bore washout at sea level will make it possible to create a sufficiently high velocity to keep the whole pipe line free from obstruction.
The scheme as proposed and above described can be
carried out to the details given, but it would be advisable to consult Pipe and Valve Lanufacturers in England before
