Points were expanded by the laying down of a further 520 permanent survey marks which involved 27 miles of main and minor traversing. 97 new Bench Marks have been fixed, mainly on the Island. The cross-harbour levelling at Lyemun Gap and from Queen's Pier to Kowloon Public Pier was completed with highly satisfactory results and the precise levelling on the Mainland was in hand.
146. Surveys were made for lease plans for 33 lots and for surrender plans for 54 lots. Some 200 lots covering an area of 218 acres were set out for development purposes, and boundary stones were fixed on 125 lots.
147. The large-scale survey completed 711 acres, mainly of the highly developed areas of Hong Kong and Kowloon, and 17 sheets at a scale of 50 feet to 1 inch were produced. A total of 39 new sheets of this scale were available at the end of the year. The compilation from these new sheets of new 200 feet to 1 inch plans was started but, as one 200 feet to 1 inch sheet contains sixteen 50 feet to 1 inch sheets, the production of an up-to-date and reliable 200 feet to 1 inch sheet series will be a long process.
148. Contour surveys covering a total area of 623 acres were made for planning purposes.
149. The following miscellaneous work was carried out:-
(a) For road widening and rebuilding schemes 5 miles of road alignment was set out.
(b) 4,030 feet of building line was set out.
(c) Surveys covering 234 acres were made for 21 Police cases. To give evidence in connection with such surveys, surveyors attended Court on 36 occasions.
(d) A plan of the Peak District was produced and published and from the numbers of copies sold appears to have met a popular demand. The production of a plan of the Central District for eventual publication was put in hand.
