170. Instruments and Machinery:—A number of indents for spares for plant were forwarded during the year and some deliveries were received. Road rollers and concrete mixers which were ordered in 1947 were received and put into full operation. Some of the plant for the rehabilitation of quarries was received.
171. Cemeteries:-A new approach road to Lo Wu Urning Cemetery and the reconstruction and rehabilitation of the existing main road at Wo Hop Shek Cemetery was completed.
172. Demolition of Defence and Other Works-Filling Japanese Tunnels:-During the year 79 separate sites were filled, many being short single tunnels although about one third of that number were complete systems of inter-connected tunnels with a number of portals. Of the latter type, the largest dealt with were the Argyle Street tunnels extending under the grounds of the Diocesan Boys' School which had been used by the Japanese as a main explosives and ammunition store. On Christmas day 1945 a heavy explosion occurred in the southern portion of the tunnels. Besides shattering nearby houses and forming enormous craters in the hillside, it shook the whole tunnel system so badly that filling operations were frequently extremely hazardous. But for the use of the concrete pump which was used to good effect in filling some of the more dangerous sections of this tunnel system, satisfactory filling could not have been achieved.
173. Government A.R.P. Tunnels: The principal works undertaken under this head were in the tunnels under Leighton Hill (North section). Work commenced at the end of December and was expected to be nearing completion by the end of the year. It was found however, that what in many cases were thought to have been ordinary collapses due to looting were large voids extending upwards to 60 feet above the tunnel roof. Completion was consequently delayed.
174. Public Recreation Areas: A separate contract was let and work satisfactorily completed of erecting chain link fencing around Children's Playgrounds at Middle Road, Chatham Road and Cox's Road. New chain link fencing was erected around a part of the Belilios Playground and the remainder of the existing fencing repaired. The playing surface was repaired, new volley and basket ball posts erected and the area marked out as required.
175. Quarries and Road Depots:--Out of the remains of a pre-war plant a temporary tar-macadam plant was erected and put into operation at Morrison Hill Quarry. Despite expected minor breakdown this plant proved quite successful and was the only source of precoated material on the Island during the year. A new quarry was set up at Hung Shui Kiu, New Territories, and was put into operation for the production of stone for road-works in this district. In addition, work of rehabilitation of the main Government Quarry at Hok Un made good progress.
As a result, production figures reached 160 tons per day of crusher run stone.
