This book was written while the author was in the last stages of a 

 severe illness, to which he succumbed on August I5th, 1910, at Wah- 

 roonga, New South Wales. William Russell Quinan was born in 

 Maryland, U.S.A., in 1848. He graduated from West Point, the 

 Military Academy of the United States, in 1870, having distinguished 

 himself for proficiency in mathematics and the physical science. After 

 some years' service in the Artillery, he resigned his commission in 

 1881, to devote himself to the development and manufacture of indus- 

 trial explosives. His first engagement was the California Vigorit 

 Powder Company. From 1883 until 1889, he was Superintendent of 

 the California Powder Works. In 1889, he was engaged by the late 

 Cecil Rhodes to build a dynamite factory in South Africa, and was 

 appointed (General Manager of the Cape Explosives Works Limited. 

 He remained with this company until the end, and it was while in 

 Australia in its interest that the last illness overtook him. He was 

 a prolific inventor, amongst his novelties being the first successful 

 machine for packing dynamite into cartridges, and a crusher gauge for 

 the testing of high explosives.

The author deals exhaustively with the subject, not merely from a 

 geological point of view, but mainly with the actual working of col- 

 lieries in the various States of the Commonwealth. The methods of 

 mining employed in different localities and by the different companies 

 in one locality ; the surface and underground machinery and plant ; 

 electrical equipments, coal-cutters, air-compressors, and the latest 

 devices adopted to make operations profitable as well as safe ; the rail- 

 way and trolley-track schemes, with detailed descriptions of rolling 

 stock, are fully described. The great collieries of New South Wales 

 naturally furnish the larger amount of the contents, but those of the 

 other States are made to contribute to the completeness of the work. 

 The illustrations include diagrams and photographs of machinery ; 

 railways, surface and underground ; coking ovens and their plant ; and 

 everything of which a more graphic idea is required than can be given 

 in words.
