Three typescripts by J. J. C. Bradfield, presented as part of the John Thomson Memorial Lectures at the University of Queensland in 1918. The first lecture, on the Murrumbidgee Irrigation Scheme, was delivered in two parts on 26 July 1918 and 2 August 1918 respectively. The first part is titled 'Burrinjuck Dam, weirs and regulators, main canals'. The second part is titled 'Water system on the irrigation areas, irrigation settlements and townships; the development of the farming, dairying, and fruit growing industries on the areas, with establishment of factories for the treatment of farm produce'. The second lecture, undated except for the year 1918, is titled 'Principles governing the location and design of the Sydney city (underground) railway'. Three typescripts originally held together with metal fasteners in a bound binder folder. Lectures separated by linen paper inserts and original typed title pages that state the lectures were delivered at 'Brisbane University'.
