The Ten Normal, 

 The location of the ten normal line in Yarmouth County 

 is clearly defined by the observations at Lake Annis and 

 Deerfield. By drawing a line roughly parallel to the coast 

 line of the Bay of Fundy, it is found to pass well inside of 

 Annapolis Basin, up through the Annapolis Valley — its loca- 

 tion being defined at Spa Springs and passing somewhere 

 north of Canning. Around the southern shore this normal 

 may be drawn in the same way, following the coast line, 

 passing north of Shelburne, crossing the LaHave River at 

 a point about five miles from its mouth and appearing at 

 Halifax, probably near Herring Cove, and from there east 

 quite close to the Atlantic Coast. Still further east it lies 

 well outside Sherbrooke, cuts across the head of Chedabucto 

 Bay, is located at Port Mulgrave, passes north of Anti- 

 gonish and through Pictou Harbor. 



The Seven Normal. 



Starting from a point south west of Kemptville in Yar- 

 mouth County, the seven normal line runs parallel to the 

 ten normal, about seven miles from it, and gradually increas- 

 ing this distance to about ten miles, according to the observa- 

 tion at Alpena, and running about three miles north of 

 Kentville and along the south shore of Minas Basin. Running 

 south from Yarmouth County the seven normal apparently 

 is only four or five miles from the ten normal, and passes 

 through Bridgewater, appearing at Halifax a little south 

 of Melville Cove, thence easterly, but still south of Musquo- 

 doboit Harbor. It passes through Sherbrooke and follows 

 the trend of the ten normal, passing just north of Antigonish 

 and through Pictou. 



The Five Normal. 



Starting at a point above Kemptville, about four miles 

 from the seven normal, running northerly, crossing the 

 HaUfax and South Western Railway at Dalhousie, at which
