HAUGHTON. — TIDES. 



2. Davis' Strait Tidal Wave, 



This tidal wave is much better known than that of Behring 

 Strait. Observations upon it have been made at —

Sound. 





This tidal wave, in passing Cape Farewell has a luni-tidal 

 interval of &" 22'", which is increased (Inglefield) to 11*" 0"' at 

 Upernavik, and to 11'" 50'" at Van Rennselaer Harbour (Kane). 

 The diurnal element is well developed along the Greenland coast. 

 On reaching the head of Baffin's Bay, the tidal wave moves north- 

 ward through Smith's Sound, and (according to Captain Mark- 

 ham) meets another tide at Cape Frazer.* The tidal wave flows 

 also through Lancaster Sound to the westward to Port Leopold, 

 where it divides into three branches, through — 



a. Barrow Strait (westward). 



b. Wellington Channel, Queen's Channel, and Penny Strait 



(northward). 



c. Prince Regent Inlet (southward). 



The progress of the tidal waves may be thus estimated by the 

 luni-tidal intervals : — 



(«). Port Leopold - - - - 



Griffith Island (Admiralty Tide Tables) - 



Dealy Island ( „ ?? ) - 



Bay of Mercy, not given (Admiralty Time 



Tables). 



(The range is given at 2 ft. in the 

 Bay of Mercy, and at 4 ft. at Dealy 

 Island ; this circumstance, and the pre- 

 sumed difficulty of fixing the time of 

 high water is in favour of the tide at 

 Mercy Bay being the Behring Strait 

 tide.)

* Captain Markham's remarks show that the diurnal element is well de- 

 veloped in the tidal wave south of Cape Frazer.
