by the Coast and Geodetic Survey and which has been 

 already referred to. A few pertinent facts may, how- 

 ever, be mentioned. 



(1) At Point Barrow, Alaska, the flood stream 

 comes from the west and not from the north, as 

 the hypothesis of an extensive, deep polar basin 

 implies. 



(2) The semidaily range of tide at Bennett Island 

 is 2.5 feet, while it is only 0.4 foot at Point Barrow and 

 0.5 foot at Flaxman Island, Alaska. This indicates 

 that obstructing land masses lie between the deep 

 basin or channel traversed by the Fram and the north- 

 ern coast of Alaska. 



(3) The observed tidal hours and ranges of tide show 

 that the semidaily tide is not propagated from the 

 Greenland Sea to the Alaskan coast directly across a 

 deep and uninterrupted polar basin. 



(4) The observed ranges of the diurnal tides at 

 Teplitz Bay, Franz Josef Land; at Pitlekaj, north- 

 eastern Siberia; and at Point Barrow and Flaxman 

 Island have less than one-half of their theoretical 

 equilibrium values based upon the assumption of an 

 uninterrupted and deep polar basin. 



In addition to these facts are the following items 

 which have a bearing upon the shape and size of this 

 unknown land: 



The westerly drifting of the Jeannette. 



The westerly drifting north of Alaska observed by 

 Mikkelsen and Leffingwell. 



The existence of Crocker Land. 



The shoaling indicated by a sounding of 310 fathoms 

 taken in Lat. 85° 23' N.
