Abstract
THE Geological Survey Branch of the Department of Mines of Canada continues to cover a wide field of research. Even its “Summary Report” for 1911 includes topographic and structural papers, in which coal-mining areas are dealt with, as well as notes on peat and clay, and (p. 316) on petroleum in New Brunswick. J. W. Goldthwait's paper (p. 296) on post-glacial changes of level in Quebec and New Brunswick continues work previously published (Mem. 10) on the shore-lines of the extinct lakes Algonquin and Nipissing in south-west Ontario. In this earlier memoir the author draws isobases across the Great Lake region, showing the warping of the beaches of Lake Algonquin and its successor, the greater uplift being in both cases in the north.
