lobate origin. Northeast of Blenheim it has a relief of 20 to 30 feet and 

 is well defined. It passes to the north of the Michigan Central Railway 

 a few miles east of Taylor. 



3. The St. Thomas Moraine. — ^Another well defined moraine passes 

 just south of Duttou and runs northeast through St. Thomas. To this 

 point the moraines of the Erie lobe are all waterlaid, but a part of this 

 moraine is probably landlaid. 



4. The Ingersoll Moraine. — This moraine runs east from London 

 along the south side of the Thames River and is in some parts a strong 

 landlaid form. Small fragments of other moraines north and south of 

 this one have been observed, but not yet traced any distance. The 

 Ingersoll moraine is probably continued in the high ridge at Mount Elgin, 

 six miles northwest of Tillsonburg. 



5. The Tillsonburg Moraine. — This is a strong, high landlaid moraine, 

 but only a small fragment of it is as yet known. 



6. The Waterloo Moraine. — This is a finely formed moraine ridge 

 running south from Waterloo to Ayr and west to Bamberg, but it has 

 not been traced farther. It is higher and more bulky than the average. 



7. The Paris Moraine. — This is one of the best known moraines in 

 Ontario, having been traced with substantial continuity from the shore 

 of Lake Erie southwest of Port Rowan to the brow of the escarpment 

 south of Collingwood, where it is found to be the same as the Seaforth 

 moraine of the Lake Huron slope. At or near Paris this moraine becomes 

 waterlaid toward the south and grows steadily lower and fainter toward 

 Lake Erie. It is still a sharply defined ridge at Scotland, but is weaker 

 at Vanessa and is quite faint east of Delhi. Farther south it is scarcely 

 perceptible as a ridge, but exerts some control over minor drainage. 

 North of Paris it is landlaid and is strongly developed. 



Inasmuch as the Ontario and Georgian Bay-Simcoe lobes had not 

 yet become differentiated, this moraine may as well be described as 

 one of the Erie group through its entire extent up to the angle south of 

 Collingwood. The Paris moraine is unusually high southwest of Gait 

 and it continues from Gait northeastward in strong development to a 

 point near Acton. At Paris and Gait it is 25 to 30 miles west of the 

 Niagara escarpment, but at Gait it trends more to the east and at Acton 

 is less than 10 miles back. From Acton to a point 6 or 7 miles north of 

 Orangeville it holds a place a few miles back of the escarpment, but for 

 a number of miles beyond it is on or very near the escarpment. It is 

 in this position west of Glen Cross and Mono Centre, east of Primrose, 

 at Whitfield, east of Honeywood and at Maple Valley. But from Maple 

 Valley to the angle west of Singhampton it lies some distance back. 

 While it is strong all along, this moraine is truly magnificent in its de-
