Quarries
258. The production of crushed granite and bitumen macadam, to meet the requirements of the Public Works Department, continued throughout the year.
259. Demands, which remained in the region of 200,000 tons for the year, were met on the Island by Tsat Tze Mui Quarry, and on the Mainland by Hok Un Quarry. The plant described in previous reports remained unchanged, but extensive modification at Hok Un Quarry resulted in the rate of production being doubled. This made possible the reduction of the working day from two to one eight-hour shift.
260. The following table shows the output from the Quarries in comparison with the figures for the four previous years:
