Content Summary:

This volume was put together by Hargrave at a later date. The papers, which mostly date from 1880 onwards, comprise correspondence, manuscripts, research notes, drawings, tables, diagrams, calculations, newspaper cuttings and photographs of models. They document Hargrave's early work on the design and construction of flying-machines. In particular, there are notes on wave movements, wave propelled models, trochoided plane principle, air compressing pump, engines, flying-machines powered by rubber bands and compressed air, and a list of expenditure on flying machine experiments.

There are reprints of several papers by Hargrave, all of which were published by the Royal Society of New South Wales: 'Notes on flying-machines' (June 1885), 'Notes on a model showing one form of serpentine progression' (June 1886), 'On a form of a flying-machine' (Dec. 1885), 'Recent work on flying-machines' (June 1887), 'Autographic instruments used in the development of flying-machines' (Dec. 1887), and 'Flying-machine memoranda' (Aug. 1889).

The correspondents include Commodore J.E. Erskine (Sydney), Prof. Archibald Liversidge (Sydney), Henry Maclaurin (Sydney), Hiram Maxim (London), Cooper Penrose (Sydney), J. Arthur Pollock (Sydney), H.C. Russell (Sydney), Norman Selfe (Sydney), John Storer (Sydney), James Thomson (Sydney), C.G. Thorp (Sydney and Wollongong), Prof. Richard Threlfall (Sydney), Rev. H. Walker Taylor (Bulli) and the Royal Society of New South Wales. Among the many letters written by Hargrave are a number sent to editors of Sydney newspapers and engineering journals.

There is an index at the beginning of the volume. (423pp)
