o m. Windsor. Alt. 26 ft. (7.9 m.). The Canadian 



o km. Pacific railway from Windsor to Truro runs in 

 an easterly direction through a district whose 

 western portion is underlain by Carboniferous 

 strata belonging to the Windsor series. The 

 gypsum beds and associated limestones and 

 shales of the Windsor series, outcrop over a 

 large area bordering the St. Croix river on both 

 sides. They extend to the south for a distance 

 of about 2\ miles (4 km.), and to the north for 

 a distance of about 15 miles (24.1 km.) almost 

 to the shores of the Bay of Minas. Over this 

 wide area, the strata are folded, crumpled and 

 doubtless, traversed by many faults. Though 

 in many places the strata are vertical or steeply 

 inclined, yet as a general rule, the angle of dip 

 is not above 30 . 



On the south, the Windsor series is bounded 

 by the wide area of the Pre-Cambrian Gold- 

 bearing series and the associated Devonian 

 granites, traversed by the railway line from 

 Halifax to Windsor. In places, narrow belts 

 of Horton (lowermost Carboniferous) strata 

 separate the Windsor beds from the older 

 measures. The Windsor beds are unconformable 

 to the Pre-Cambrian and possibly are also 

 unconformable to the Horton. On the north . the 

 Windsor beds are bounded by a narrow band, of 

 irregular width, of sandstones, shales, slates, etc., 

 which by Hugh Fletcher were considered to be 

 Devonian and to unconformably underlie the 

 Windsor strata. At least a portion of these 

 so-called Devonian beds are the equivalents of 

 the Horton series and therefore of Carboniferous 

 age. Other portions may be the equivalents of 

 the Riversdale-Union series and, if this be the 

 case,, are younger in age than the Windsor series.
