Geology
There is no book dealing specifically with the geology of Orkney. Recourse must be had either to books dealing with the science generally, or to those dealing with the Islands in which their geology is included.
The Orkneys and Shetland (Tudor) contains an account of the geology of the islands, written by Drs. Peach and Horne, with a useful geological map.
The most recent and complete geological survey of Orkney is that by Dr. J. S. Flett, an account of which is contained in two papers in the Transactions of the Royal Society of Edinburgh.
Some of Hugh Miller’s works, such as The Testimony of the Rocks, The Old Red Sandstone, Rambles of a Geologist, and Footprints of the Creator, contain numerous references to the geology of Orkney.
Robert Dick, by Dr. Samuel Smiles, is an interesting account of a Thurso baker who devoted his life to the study of geology in Caithness, where the rook formation is the same as that of Orkney.
Among general works in geology suitable for beginners may be mentioned Huxley’s Physiography and Sir Archibald Geikie’s Outlines of Field Geology, his Class-book of Geology, and his Scenery of Scotland.
