Now I will pass on to discoveries made within the last few months up to the first week in November, 1894, of further proof of land glaciation at low levels, in substantiation of my paper on this subject read before the Royal Society last August. Upon examination of the banks of the King River, which flows into Macquarie Harbour between Pine Cove and the settled portion of the town of Strahan, I discovered large ice-worn boulders striated and grooved in the deep gorge of the river situated at the Upper Landing ; also similar glaciated boulders in Harvey's Creek at a distance of a quarter of a mile from its junction with the King River at the Landing. The boulders are large, many tons in weight, and are composed principally of Silurian sandstone. The planed surfaces, grooves, and striaa are fairly distinct, proving beyond doubt that as the ice marks are not obliterated in so friable a rock that the period of their transposition by ice is of a very recent date. As there are conclusive proofs that the whole mountain chain comprising the West Coast Range has been covered with a vast sheet of ice, we must conclude that rivers of ice have flowed down the damp, sunless, slate gorges of the King River, collecting as they went masses of sandstone from the surrounding heights, leaving them at a, altitude of not more than 100ft. above sea level in their present shape and position at the Upper Landing and Harvey's Creek, distant about four to five miles from the range.

The article is listed with the title in the volume contents "Proofs of glaciation at low levels in Tasmania". In 1843 the Horticultural and Botanical Society of Van Diemen's Land was founded and became the Royal Society of Van Diemen's Land for Horticulture, Botany, and the Advancement of Science in 1844. In 1855 its name changed to Royal Society of Tasmania for Horticulture, Botany, and the Advancement of Science. In 1911 the name was shortened to Royal Society of Tasmania..
