Boundary of New South South Wales and South Australia.... Report on the Determination of the Boundary Line of the Colonies of South Australia and New South Wales, by Charles Todd ..
Adelaide, Government Printer, 1869.
Foolscap folio, 12 pages plus a folding map (335 x 315 mm).
Drop-title, neatly disbound (with holes in the inner margin where formerly stab-sewn); minimal light foxing to some edges; a fine copy.
A detailed report, outlining the history of the inaccurately determined 141st meridian of east longitude, resulting in a strip of disputed land between Victoria and South Australia. The electric telegraph connecting the observatories of the three colonies afforded a more accurate means of determining the meridian, and this report explains the procedure; the map shows 'the exact position (north of the Murray) of the said boundary line, and the relative position, at its northern extremity, of the present boundary line of South Australia and Victoria'. South Australian Parliamentary Paper Number 182 of 1868-69.
