Last August, during the meeting in Winnipeg of the British Association for the Advancement of Science, an excursion by 16 of the geologists in attendance was taken for examination of the esker named Birds Hill, adjoining the station and little village of Birds Hill, 8 miles northeast of Winnipeg, on the old and original main line of the Canadian Pacific Railway. This esker, a ridge of sand and gravel, extensively excavated for building and street uses, has a length of about 4 miles to the southeast and east from that station. Both the old line of the Canadian Pacific Railway and its newer line on the south have spur tracks or short branch lines for bringing the sand and gravel from the many and long excavations by which much of this esker at each end and along the greater part of its course is being removed . . .
