Recommendation that trigonometrical
Information regarding these points was asked for in a letter sent to the Colonial Survey Committee on the 28th June, 1927, and forwarded by them to the Government of Hong Kong. No reply has yet been received. Information was also asked for by cable to G.O.C. Hong Kong regarding the geographical coordinates adopted for Kowloon Observatory and the methods of computation, projection, and figure of the Earth employed. The reply gave the values for Kowloon but stated that no information on the other points was available.
From this it appears that the trigonometrical framework values for controlling the new maps at Hong Kong is of an order of accuracy which barely justifies the production of a map on the scale of 1/20,000, and that the production of maps on a larger scale cannot, at present, be contemplated.

The Survey Sootion in Hong Kong is a separate department but is a branch of the PV.D. appears from the reports of the Colonial Survey Committee that the department is so much occupied with settlement surveys that it has been quite unable to spare the personnel to put its trigonometrical frame work on a satisfactory basis. This is confirmed by the fact that when the Colonial Survey Section was in Hong Kong every assistance was given by the Department with the exception that it was not found possible to cooperate in the field work, and it was not possible to amplify the information already given about the trigonometrical framework.
As the original records of the Survey are not available it appears to be very advisable that the framework should be trigonometrical framework should be re-observed ab re-observed.
initio both with a view to making full use of the figures now available, and with a view to coordinating the land settlement surveys as the country become s fully occupied.
The whole Colony is now covered by a framework of points on the ground, the gaps in the P.W.D. system having been filled by the points observed by the Colonial Survey Section. No reconnaissance for the new triangulation would therefore be necessary, it being only necessary for the old stations to be re- occupied.
