59, Typhoon and Rainstorm Damages.-The heavy rains of the 12th to 17th June, (16.59 inches in 6 days) of the 1st to 4th August, (18.36 inches in 4 days) and of the 19th to 22nd September (11.98 inches in 4 days) caused numerous landslips scattered over a great number of roads. A large landslip occurred on the south side of Pokfulam Road, below the new filter beds, and it was found necessary to extend for a further length of 84 feet the retaining wall which was erected in 1917. There were also very heavy landslips on the Taitam Road and on the new road to Deep Water Bay which completely blocked these roads. Wanchai Gap Road, near the District Watchmen's quarters, was carried away by a landslip necessitating the erection of a substantial retaining wall. Advantage was taken of a heavy landslip on Kennedy Road, east of the Public Laundries, to improve the alignment of the Road at this point.
The surfaces of those roads treated with bitumen suffered only to a trifling extent from rainstorm damage and the gradual extension of this method of treatment is reducing the damage caused by rain scour to a minimum.
Considerable quantities of sand, &c., which had been washed into the various nullahs and storm-water drains were removed and repairs were effected where necessary. In the case of the nullahs east of I.L. 1485 and east of I.L. 1633, improvements in the alignment and gradients were made in the neighbourhood of May Road in reinstating the damaged portions.
60. Stores Depreciation.-The adjustment of store values and re-conditioning of old stores have been met from this head, and also the loss incurred by the sale of obsolete and unserviceable stores, the total amount of these items being $300.58.
A sum of $88.10 being rebate on freight charges in connection with stores purchased in England through the Crown Agents was credited to this item, also a sum of $1,811.57 due to the return of stores issued prior to 1918.
The result was that, instead of shewing any expenditure, the vote shews a credit balance of $1,699.09.
61. Maintenance of City and Hill District Waterworks.-The year opened with constant supply by house services in force in all districts and except for a period of 9 days, (29th May to 6th June, inclusive), during which it was necessary to discontinue the supply by house-services, in the Rider Main Districts and to substitute supply by street fountains, this system was maintained throughout the year.
The necessity of having recourse to street fountains for the brief period mentioned arose from the fact that, owing to the long drought, the gravitation reservoirs became practically empty and, as one of the new engines at Taitam Tuk was incapable of being worked, owing to a cracked cylinder, the available pumping plant was inadequate to maintain the full daily supply. The substitution of supply by street fountains in the Rider Main Districts reduced the con-
