Book Description
Excerpt from Transactions of the Geological Society of Glasgow, Vol. 1: Part II, on the Phenomena of the Glacial Drift of Scotland The chief addition to the agents demanded by Hall's hypo thesis was the introduction of ice as a means of transporting large masses of rock. Though the carrying power of ice had been so clearly pointed out by Playfair at the beginning of the century, yet his remarks for thirty or forty years appear to have been altogether forgotten. Hardly, however, had the speculations of Mr. Smith appeared, preceded and accompanied as they were by those of Sir Charles Lyell on the upraised deposits of Sweden and the sands and clays of Norfolk, ' when light from a new quarter began to dawn on the dark and obscure history of the Drift. Already in an address read before the Helvetic Natural History Society in the summer of Agassiz, following up the suggestion of Playfair and the bold speculations of Venetz,3 announced his belief that Switzer land had once been sealed in ice, that its rocks owed their present grooved and polished surfaces to the passage of this icy sheet over them, and that to the same cause was due the transport of enormous blocks of stone from the Alps to the J ura. In the following year, Dr. Buckland, under the guidance of the Swiss naturalist, examined these phenomena on the spot, and by witnessing the effects of actual glaciers, became convinced that the grooving and striation of the rocks of the British Isles, and the position of the erratic blocks there, though now far removed from any glacier, were, nevertheless, due to the same agency which is now grinding and polishing the sides of the higher valleys of the Alps.

Book Description
John K. DeLaski, M.D. practiced medicine in the Penobscot Bay region of Maine and, in addition, was a naturalist with keen powers of observation. His study of the landscape led to the conclusion that a thick glacier had overtopped the highest hills, flooded all of Penobscot Bay, extended far to the east and west and probably was part of a greater continental glacier. He published these very critical field observations and inferences in numerous articles in local newspapers and magazines, and in the American Journal of Science in 1864. His work put him on the “team” of Benjamin Silliman, James D. Dana and Louis Agassiz as an advocate for glaciation as the regional land shaping force opposed to that of the Biblical Deluge, a major scientific conflict of the day both in North America and Europe. He remained a shadowy player, in the background, but clearly contributed critical observations to the argument through personal interactions with Agassiz and other prominent naturalists. They incorporated DeLaski’s observations into their own presentations, often without giving him credit. John DeLaski’s summary work, a 400 page handwritten manuscript for the book, “The Ancient Great Glacier of North America”, was dated 1869. He died in 1874 and the book was not published. The historic significance of DeLaski’s unpublished book is based upon its startling contribution to one of the major scientific questions of the day of whether the surficial geology of northern U.S. and Canada was caused by the actions of the Biblical Flood or by continental glaciation. If published, this would have been the first book on this continent, at least, to present a holistic discussion of the controversy in which he presented his critical observations of the surficial geology in Maine, southern New England and New Brunswick, Canada and concluded that these depositional and erosional features must be of glacial origin. DeLaski then incorporated other evidence into the book for glaciation reported by others from the region during a decade or two, and from the mid and far west and Canada to advocate that the entire region was covered by an ice sheet that was at least 5,000 feet and probably much thicker over interior northern U.S. and Canada and which terminated along a glacial margin which extended from southern new England as far westward along the courses of the Ohio, and Missouri Rivers. All this was done while most “naturalists” still advocated the Biblical Flood to explain the major components of the surficial geology in North America and abroad. DeLaski’s book containing his critical observations of clearly so many landscape features of glacial origin, if published would have been a pivotal document that would have strongly supported those arguing for glaciations in the glaciations vs. flood international argument.

Book Description
Studies in the Scottish Lateglacial Environment presents information on environmental reconstructions and dramatic changes, as well as the important implications of studies of the Lateglacial environment for Quaternary studies and modern climatic variations. Composed of 10 chapters, this book begins with a review of the Late Devensian glaciation in north-east Scotland. Then, detailed evidence concerning Lateglacial sea-level changes in the Earn-Tay area and their relationship to deglaciation is presented. Subsequent chapters explore the validity of the Oban-Ford Moraine, the only pre-Loch Lomond Readvance moraine remaining virtually unchallenged in the literature; reconstruction of Lateglacial and early Flandrian environments in south-west Scotland; and the fauna in marine sediments at Lochgilphead. Other chapters describe results of pollen-stratigraphic investigations at six Lateglacial sites in the southern and eastern Grampian Highlands; analyses of biological and chemical variables from sediment profiles from lochs in northern Scotland; and radiocarbon dates that are related to pollen profiles from the Scottish Highlands and the Isle of Skye. This book will be of value to students of Quaternary, as this text provides an integrated survey of available information in this field.
