Q 2
if too great a head of water were allowed to accumulate between the wall and the filling.
Tunnels.
All Tunnels are now completed.
At Beacon Hill the headings met satisfactorily on 17th May, 1909, and since then the work has been rapidly pushed to completion. The Tunnel is lined throughout with a varying thickness of brickwork in cement. The treacherous nature of the rock rendered lining imperative, and as it was found impracticable to line the roof only, in portions where the rock was less liable to slide, a thin skin of brickwork built tight to the excavation has been put in. There does not seem to be any use in perpetuating the shaft on the North Face which is too near the portal to be of any service as a ventilating shaft, and as it would have cost a great deal more to brick it up than the estimated cost of six thousand dollars, owing to the very wet nature of the ground, the shaft will be filled in and suitable arrangements made to cope with the water which comes down it.
At Taipo Tunnel the heading met on the 28th April, 1909, and the work is now completely finished. This tunnel has been very creditably and cheaply constructed.

Road diversions in connection with the Kowloon-Taipo Road are well forward and the fencing and draining alone remains to be finished. The excavation and piling for the bridge in connection with the Road Diversions at Gascoigne Road at Hung Hom has been completed. It was decided to get the spoil for the road from a site at back of the Match Factory, referred to above, thus saving further land acquisition.
Bridges.
The Bridgework has been completed with the exception of the Road Bridge No. 2 at Mile 1 and the rebuilding of Bridges Nos. 4, 5, 7, 8 and 12 which have failed owing to faulty design in foundations in very treacherous ground and to bad material. Some other bridges are being strengthened. The cost due to this cause is estimated not to exceed $95,000.
Telegraph.
The telegraph line was laid throughout the Section but only some eight miles of it is in the permanent position. This is now being taken in hand.
