grading feeders under the main hoppers. The "Marsden" unit is fed by shutes from the main storage hoppers. Bitumen is piped from a "Clarmac" 3,500-gallon electrically heated boiler and from two 1,000-gallon oil-fired boilers. The output of each mixing unit is 125 tons per 8-hour day. As was to be expected, The new installation at Tsat Tse Mui was not without its teething troubles. Unfortunately sited in a residential area, considerable nuisance was caused by dust, necessitating the construction by the Mechanical Workshops of a dust extraction plant. The crushing plant was completely housed-in and temporary blowers, ducts, and collecting channels installed, but this was not completely successful in abating the nuisance.

159. With the increased demand for all sizes of crushed stone and bituminous macadam, it was necessary during the latter half of the year to work two 8-hour shifts at both quarries. This had the effect of increasing the annual production at Hok Un from 47,000 tons of stone to 60,000 tons.
