95. Resumption for Public Road through Marine Lot 29 from Queen's Road East to Praya East.-This matter was referred to in para. 28 of last year's report. The compensation agreed upon was paid during the year and the road was formed with the exception of a short length adjoining Praya East. It was named Gresson Street. In addition to compensation for the area required for the road, the amount due in respect of scavenging lanes was defrayed from this vote. The respective amounts were as follows:-
Sq. Ft. $ Public road, 30 feet wide, 7,906 15,812.50 Scavenging lanes, .. 2,319 4,639.00A sum of $388.74 for certain lots to the South-east of Fan Ling Station, which had been resumed in connection with the Railway but were found not to be required for it, was erroneously charged to this vote and, as the Treasury Books for 1909 had been closed before it was discovered, the error could not be rectified.

96. Albany Filter Beds, Reconstruction and Extension.—The contract for the reconstruction and extension of the Albany Filter Beds was completed by Messrs. Sang Lee & Co., the Contractors, in August.
The work comprised the demolition of the old watchman's quarters and the erection of new and enlarged quarters in a different position to accommodate the watchman and coolies employed in sand-washing, &c.; the construction of one entirely new bed next the Peak Tramway and the deepening and enlarging of the old beds, six in number, but now converted into seven, making a total of eight beds and increasing the filtering area from 3,246 to 4,945 superficial yards or by fully 52%. During constant supply, the quantity of water passing through these filter beds amounts to about 2,950,000 gallons per day or at the rate of about 700 gallons per square yard, assuming one bed to be always out of operation for cleaning purposes.
The new filter beds and gauge basin were constructed at a lower level than the old and the 6' 0" rectangular gauge was fixed 12 feet below the level of the old gauge. In addition to enabling an accurate measurement of the water passing it to be obtained, which was generally impossible hitherto on account of the flooding of the gauge, this arrangement admits of the necessary quantity of water for the supply of the City being passed through the conduit without a certain proportion of it overflowing and running to waste as has frequently occurred during recent years.
Eight 10" Venturi meters were fixed, one to each bed, for recording the quantity of water passing from the filter beds to the Service Reservoir. The records obtained show at a glance whether the rate of filtration is being properly regulated.
