Positions. — The positions of all Stations and other points on the water, 

 are thus defined by a direction and distance from some point on the land, or by 

 their mileage along a line between definite points; so that they can readily be 

 laid out on a chart or map. 



Arrangement 



The open waters of the Atlantic, off Nova Scotia and southeastern New- 

 foundland are given first; as they show the temperatures and densities in the 

 ocean, and thus afford a term of comparison for those elsewhere. 



The two passages which connect the Gulf of St. Lawrence with the Atlantic 

 through Belle Isle strait and Cabot strait, are given next; followed by the open 

 waters of the central portion of the Gulf, the entrance to the St. Lawrence in 

 the vicinity of Anticosti island, and Northumberland strait. In these regions, 

 the observations in different years are arranged in order of date during the 

 season. 



The central part of the Bay of Fundy and its offing as far as southern 

 Nova Scotia, complete the regions examined. 



Plates. 



The location of the Stations at which anchorages were made, are shown in 

 the accompanying Plates. The general map of the Gulf of St. Lawrence shows 

 the Stations in the open Gulf, and in Northumberland strait. The Strait of Belle 

 Isle and the Gasp^ region are given in the next two Plates; followed by south- 

 eastern Newfoundland and the Bay of Fundy. 



At the Stations thus shown, temperatures were taken at various depths 

 during the season. These Plates also serve as maps to show the location of the 

 lines of temperatures and densities, and the sections, which were obtained. 



Tides and Currents. 



A description of the behaviour of the currents and tidal streams in these 

 various regions, is given in the following publications issued by the Tidal 

 Survey: — 



'The Currents on the South-eastern coasts of Newloundland", and the 

 amount of indraught into the larger bays on the south coast. 



^'The Currents in Belle Isle strait", from investigations during two seasons. 



"The Currents in the Gulf of St. Lawrence", including Cabot strait and 

 Northumberland strait; and explaining the general circulation of the water. 



''The Currents in the Entrance to the St. Lawrence", including the Anti- 

 costi region, and the Gasp^ current; from investigations during three seasons. 



"Tables of the Currents in the Bay of Fundy." Giving the direction and 

 velocity of the tidal streams, hour by hour, and the time of slack water, through- 

 out the region extending from St. John, N.B., to Cape Sable.
