for the year 1864. ' lxxxiii 



has now gradually progressed over a large portion of the 

 country. 



The objections that were raised so loudly against this 

 method of surveying at first, arose in great measure, no 

 doubt, from a mistaken statement made in Parliament that 

 it was intended as a cheap substitute for the great Trigono- 

 metrical Survey, and was to supersede it These objections 

 have by experience proved practically fallacious, and have 

 died out 



Large tracts of country have been laid out under the 

 Geodetic system in great blocks, each of which is then 

 subdivided by 'contract surveyors, for sale. The great 

 advantage is thus obtained of immediately embodying these 

 numerous contract surveys in the general map of the colony 

 with precision ; and it is admitted by those undertaking the 

 subdivision of blocks by contract, that much greater despatch 

 and accuracy is obtained in their undertaking when the 

 blocks are laid out geodetically. 



The geodetic division of lands, of course, has only been 

 applied to unsurveyed country, but the work of the geodetic 

 surveyor extends beyond this : his duty is to afford data for 

 the construction of an accurate map of the Colony, and this 

 involves not only the connection of all the surveyed lands, 

 but the erection of marks spread over the country, so that 

 any future surveys may be at once accurately placed on the 

 maps, and the survey of the boundaries of runs facilitated. 



The great General Survey of the Colony is thus being- 

 done by the prosecution of the Trigonometrical Survey in. 

 connection with the Geodetic work proper. Trig, stations are 

 erected, and their positions fixed, and lines (meridians and 

 parallels), are run from those trig, stations, traversing the 

 colony in all parts. 



The Survey extends now from the western boundary of 

 the colony to thirty or forty miles to the east of Port Albert,
