 Kilometres. 



4.6 m. At Davenport there are gravel bars of 



7.4 km. glacial lake Iroquois, while two miles to the east 

 the old shore line of this lake is exposed. 



22.4 m. At King an altitude of nearly 1,000 feet is 

 36.1 km. attained. The country traversed consists of 



rolling ridges of Pleistocene deposits, made up 

 of stratified clays, sands and gravels, and 

 material of glacial origin. To the north of King 

 much of the country is strewn with boulders. 

 48.7 m. The first view of lake Simcoe is obtained 



78.6 km. from a point just south of Gilford Station. 



62.7 m. At Allendale a splendid view is obtained 



101.1 km. of the town of Barrie on Kempenfeldt bay. To 

 64.0 m. the south of Barrie, as far as the township line, 



103.2 km. the drift has an average depth of 300 feet or 



more. " Throughout this area of deep drift a 

 considerable part is made up of water laid or 

 lake sediments as distinguished from glacial or 

 ice-laid deposits. Locally, as in the case of the 

 high mass west of Barrie, a large part is water 

 laid — chiefly stratified sands and clays. But ice 

 laid drift is generally dominant" (Taylor). 

 86.0 m. North of Orillia there is a cutting through 



138.7 km. boulder clay. All the country from Toronto 



north, as far as Longford, is underlain by flat- 

 lying sediments of Paleozoic age, including, from 

 the south, Lorraine, Utica, Trenton, Black River 

 and Bird's Eye formations. The first outcrop- 

 ping of rock along the railroad occurs at 



93.5 m. Longford, where Black River limestone is seen. 



150.8 km. At the Longford quarries, on the west side of 



St. John lake, Rama township, four feet of 

 Black River limestone are exposed at the top, in 

 two heavy layers containing an abundance of 

 characteristic fossils, such as Columnaria Halli, 

 Stromato cerium rug sum, etc., and a six-foot 

 bed at the bottom is a mass of Tetradium fibra- 

 tum. Below this are twelve feet of fine-grained 

 blue and dove-colored limestone containing 

 Leperditia, but comparatively few other fossils. 

 This lower bed has been referred to the Bird's 

 Eye formation (Johnson).
