"It is a useful book for those engaged or otherwise interested in our coalfields, and deals in an exhaustive way not only with the fields of each of the States, but also with such matters as ventilation in coal mines, irregularities in coal seams, interpretation of analyses, heating powers of coals, selling agencies, shipping facilities, labour troubles, and there is a special chapter treating of the Victorian State coal mine, which is contributed by Mr. Geo. H. Broome, its general manager. There is no doubt that the work is by far the most complete and exhaustive that has ever been issued in the Commonwealth". (Review, Sydney Morning Herald, 15 Dec. 1915).
