Mr. R. Dixon to Surveyor-General Mitchell.
Sydney. 18th July. 1836.
With reference to your memo, of 15th Inst, requesting to know the date of my appointment, also the several general instructions received by me, and the nature of the duties consequent thereon, in order to enable you to reply to the Colonial Secretary's letter No. 36/578, I have the honor to inform you that I joined the Surveyor General's department as Assistant -Surveyor in September 1826. My first employment was about Sydney and its environs, after which I proceeded to Illawarra in an open Boat and surveyed the Coast from thence to Botany Bay, taking up Port. Hackery, the Southern Shores Botany Bay. George's River and its branches. I was then ordered to survey the unmeasured grants in the Cowpastures, and to extend the survey to Burragorang. Werraberri Creek, the Notai River, part of Coxes river, the Warragumba find the Wollondilly to Goulburn Plains. which I accordingly did: this includes the principal duties performed under Mr. Oxley.
My next instructions were from Major Mitchell to join him in the Trigonometrical Survey of the Colony, when I accompanied him over the Southern districts on that duty and have since extended angles over the whole Colony.
In the interim I completed the trace of the principal features South and South West of Goulburn Plains, including Lakes Bathurst and George, the Molonglo River, part of Murrumbidgee, the Yass River, Narrawa and Lachlan Rivers, and several of their branches, as well as the dividing range from Burrah Burrah to Lake George, and also a great many Grants in the Southern Counties.
My next movements were in the Western Districts, where I completed a detailed survey of the whole Mass of broken country between Mount Victoria and Bathurst, previously to Major Mitchell's laying out the new line of road between these points; after which I was engaged in measuring grants in that neighbourhood and on the Lachlan River, etc. These were the principal Instructions received and duties performed by me up to the beginning of the year 1831 : but there were many works of minor importance, particularly farms in the County of Cumberland, etc.
In the year 1831, I received instructions to proceed to the Upper Hunter River districts for the purpose of laying down the principal features in the North West Districts. I commenced by measuring a Base line on Liverpool Plains of three miles in length, from which I fixed the principal heights in that part of the Colony, and was enabled to connect, these points with the former Trigonometrical Survey. I then traced the whole of the dividing range from the head of the Coolahburragundy Stream to Mount Royal, and thence to Mount Arthur. I then took up the survey from the head of Page's River across Liverpool Plains to Peel's River, shewing the courses of the principal Ranges and Streams in that country: after which, I laid down the Whole of the Upper Hunter's River from its confluence with the Goulburn to its source, including its several branches, the Page, Kingdown Ponds, Dart Brook, with many minor tributaries and a great number of Grants and purchases thereon. I also completed a detailed survey of the country between Patrick's Plains and Muscle Brook, likewise between Lemmington and Muscle Brook, shewing the old lines of road between those points previously to the Surveyor Generals making the new line of road from Lemmington to Muscle Brook, which line I have since surveyed. I was then engaged in the survey of the principal streams in the Counties Brisbane and Bligh, viz., the Wybong, Gungal. Gummum, Bogibri. Krui, Munmurra, Talbragar and Coolahburragundy. with the whole of the Grants and purchase on those Streams with a few exceptions.
In the Month of October, 1833, I received Instructions from Major Mitchell when at Maitland to go to Wellington Valley with my equipment and from thence to explore the unknown country laying to the West, winch I accordingly did, and reached the Bogan, followed many miles down that river, and returned to Wellington Valley after having travelled upwards of six hundred miles since my departure from that station. I then came to Sydney for the purpose of re-fitting my equipment.
In the Month of May. 1834, I left Sydney for Upper Hunter's River, where I have been employed principally in the measurement of lands for sale and have surveyed since that date two hundred and forty six thousand, eight hundred and ninety Acres of Land. I have also traced the river Isis, and marked and surveyed a new line of road from Muscle Brook to Liverpool Plains with many other surveys, and, since the period of my appointment, I have not had more than two months' leave of absence from duty.
