with only one qualified Land Surveyor on the spot instead of three, to supervise the work and the day to day administration of the three camps, output has been rather less than was originally hoped for.
151. Although referred to as a Cadastral survey, the survey work proper consists of a large scale survey, 100 feet to 1 inch, from which the new Cadastral plans will be prepared.
152. To relate all work to the Colony system of control points has required a considerable increase in the density of control, which, over most of the area, consists only of triangulation stations on the tops of the highest hills.
153. During the year the number of control points in the three areas being surveyed was increased by the addition of 26 minor triangulation stations, plus 3 which had been destroyed and were re-established and one repaired. One major triangulation station was also found damaged and was repaired. An additional 550 permanent survey marks were laid down involving 37 miles of main and minor traverse.
154. On the detail survey work 3,374 acres were surveyed which involved over 100 miles of detail traverse. 23 sheets were completed, making a total of 30 of these basic survey sheets now available. Field work was hindered on 60 days due to weather conditions and other causes such as the curfew imposed during the October riots.
