There is a good deal of dispute as to their origin, though the 

 original materials of the iron ranges are admitted by all to 

 have been sediments of some kind. 



The map of the Moose Mountain iron deposits has been 

 prepared, by Mr. E. Lindeman of the Mines Branch at 

 Ottawa, who recently carried out a detailed magnetometric 

 survey of the property.

o. Altitude 254 feet. (77.4 m.) Leaving Toronto 



(Union Station), by way of Parkdale and West 

 Toronto, the train passes through a manufactur- 

 ing district as far as Weston. The country is 

 heavily covered with Pleistocene deposits, con- 

 sisting of boulder clays, and stratified clays, 

 sands and gravels, which conceal the underly- 

 ing Paleozoic rocks. At Weston the clay is 

 used for the manufacture of red brick. 



-The surface presents on the whole a rolling 

 appearance, and is very suitable for farming 

 purposes. Sometimes the surface is intersected 

 by ravines, and sugar-loaf hills have been carved 

 from the drift, as around Woodbridge and 

 Humber. 



About 70 miles (no km.) north of Toronto 

 old lake deposits become abundant. ..Half a mile 

 south of Carley, stratified sand showing cross- 

 bedding is splendidly shown in a ballast pit east 

 of the track. 



96. m. One mile north of Cold water.. Junction ' the 



154.5 km. first outcroppings of rock occurs These are of 



banded gneiss of Laurentian age projecting as 



rounded knobs through the drift. 



99. m. North of Lovering rock exposures become 



159.3 km. more frequent, and soon a typical Laurentian area 



is entered.
