Abstract
The subject of which this paper treats has already been traversed by the author in his Presidential address to the Geological Section of the Australasian Association for the Advancement of Science, at its meeting at Brisbane in January 1895. The author hopes, however, that the presentation to this Society of a summary of these previous records,—with the addition of his subsequent field–work in 1895,—will be justified by the opportunity now given of a discussion which will be of immense benefit in furthering an important and interesting branch of geological investigation. The personal observations recorded in this paper are the result of 13 years‚, more or less constant, field-work in Australia. I. Work done by previous observers. The first actual record of evidence of ice–action in Australia is probably that made by Dr. A. R. C. Selwyn in 1859. The statement is as follows :— At one point in the bed of the, Inman I observed a smooth, Striated, and grooved rock–surface, presenting every indication of glacial action. The bank of the creek showed a Section of clay and coarse gravel; or drift, composed of fragments of all sizes irregularly interbedded through the clay. The direction of the grooves and scratches is E. and W. in parallel lines; and though they follow the course of the stream, I do not think they could have been produced by the action of water forcing pebbles and boulders detached from the drift along the bed of the stream. This is the first and only
