Abstract
IN the Summary report of the Geological Survey of Canada for 1896 Mr. W. F. Ferrier directed attention to the occurrence of corundum crystals in the township of Carlow, Hastings County, Ontario, and to the probable economic importance of the discovery. This announcement led to the opening up of what has become the largest corundum mining industry in the world. In 1910 an important memoir by Adams and Barlow on the general geology of the district in which the corundum-deposits occur was published by the Geological Survey (Geology of the Haliburton and Bancroft Areas, Memoir No. 6), but the details as to these deposits were reserved for fuller treatment than was possible at that time. They are now given in the present volume, together with a general account of the occurrences of the mineral in other parts of the world.
