Thomas Ij. Mitchell, in December, 1831, but he kept along the 

 western side, and refers to them throughout as the Nundawar 

 Range, this evidently being the native name, although Mitchell 

 does not say so in his journal. He gives an outline drawing of 

 these mountains as viewed from the westward, and quotes names 

 for the most prominent peaks from north to south in the following 

 order : — P^iddell, Courada, Lindesay, Kaputar, and Forbes. 

 Mitchell writes:— "That great range terminates in three principal 

 heads, of which Mounts Riddell and Forbes are the noi'thern and 

 southern, the central or highest being named Mount Lindesay."* 

 Mount Forbes, which is near the south-western extremity, was 

 named after Captain Forbes, of the 39th Regiment, and it is not 

 unlikely that Mount Lindesay was named after the; then Acting 

 Governor, Sir Patrick Lindesay, while Courada is a native name. 

 Mount Kaputar, or more especially the bluff towards its south- 

 eastern side, is now locally known as Mount Lindsay (spelt 

 without an e). 



Barraba occupies an area of Devonian and Carboniferous 

 formations, the former containing fairly abundant fossils of 

 Lepidodendron austrcde, and is about 1,650 feet above sea-level. 

 From Barraba past May Vale to Mount Lindsay Station is a dis- 

 tance westerly of nearly 30 miles, the altitude at the homestead 

 being about 3,000 feet, and the ascent from May Vale, which is 

 situated about half-way, nearly 1,000 feet. Carboniferous shales 

 are met with between Barraba and May Vale, and afterwards 

 areas of basalt and acid volcanic agglomerates are passed. 



The Nandewar Mountains consist of a series of peaks composed 

 largely of alkaline rocks, and which have, for the most part, a 

 general N.N. west and S.S.east direction, while the western side 

 presents a steep face towards the plains around Narrabri.f 



From the eastern side, a range less than 2,500 feet high in 

 places, and known as the Nandewar Range, passes between 

 Barraba and Bingara and connects with southern New England.
