visited. Minor beacons K.P., No. 64, No. 85, Middle Island, Gin Drinkers Bay and P.W.D. Shatin were rebuilt, and Nos. 87, 134, 135 and R9 were repaired.
(f) The following 9 minor trig. stations were valued during the year to colony coordinates by triangulation: --Causeway Bay, Sham Tseng, Tsing Lung Tau, Gin Drinkers Bay, P.W.D. Shatin, R4 Tai Wai, R5 Wong Uk, R6 Turret Hill West and No. 108 Monks' Head Hill. A further 15 stations were also valued during the year to colony coordinates by triangulation and checked by coordinate conversion computation from a list of transverse mercator military metre coordinates. They were Nos. 54, 64, 73, 74, 75, 76, R2, R7, R8, R9, R25, R26, R27, K.W.W. 15 and K.W.W. 16. In addition, provisional colony coordinates were found for the following 17 stations by coordinate conversion computation from the list of military metre coordinates:-Nos. 43A, 49, 53, 77, 81, 82, 83, 84, 85, 86, 88, 108, R4, R5, R6, K.P., and M.122, and similarly for 3 tertiary points M.3, M.11 and M.16. The geographical coordinates of Mt. Kellett Minor Trig. Station No. 35 were computed.
(g) The following 12 tertiary points were fixed by triangulation: --Fundamental Bench Marks 'B' Kowloon Reservoir, 'C' Shatin, 'I' Tsun Wan, Triangulated P. Box Tsun Wan, Reference P. Box near R25, Hill 126 Tai Lam, nail Sai Wan Military Cemetery, Monuments M.1 & M.2 Jardine's Lookout site, Monuments A & B Mount Butler site and Triangulated P. box Middle Gap Road. A small tertiary triangulation of 26 points at Jardine's Lookout site covering about 80 acres and another of 24 points at Tai Lam covering about 193 acres was carried out.
(ii) Revenue Surveys and General:--The general survey work carried out during the year not specifically included under other heads was as follows:
Hong Kong Island:
(a) Half a mile of coastline at Island Bay and Rocky Bay was surveyed and plotted on scale 1:600 survey sheets and a further half a mile at Deep Water Bay, Big Wave Bay, Turtle Cove and Telegraph Bay was surveyed and plotted on scale 1:600 independent plans. About half a mile of the Cape Collinson Road was surveyed and plotted on survey sheets.
(b) Areas of 9 acres and 1 acre respectively were flagged out for inspection at R.B.L. 21, The Peak, and at Deep Water Bay.
(c) Measured mile and one and a quarter mile marks were placed on King's Road for use of the Police Department.
(d) Six bathing beaches, viz:-Island Bay, Rocky Bay, Deep Water Bay, Big Wave Bay, Turtle Cove and Telegraph Bay to a total of 17 acres were surveyed and plotted to scale 1:600 for use of the Urban Council. In addition, tent areas at Repulse Bay, Stanley Beach, Island Bay and Big Wave Bay to a total of 12 acres were set out and marked with monuments.
