Sabine and Clarence Head. Unfortunately no map of his work has 

 ever been published, but from various other sources (Peary, 1903) and 

 (Sverdrup. 190-t) we have been able to locate several which in order, 

 nortli to south are: Lefferts, Alfred Newton, Bliss, James, Sparks, 

 American ]\Iuseum, John Ross, American Geographical Society, and 

 several unnamed glaciers. Three unnamed glaciers lie soutli of 

 Clarence Head. MacMillan (1918, p. 302) states that the whole 

 coast line around Boger Point, latitude 77° 25' N., is one vast pied- 

 mont glacier, this the one named in honor of the American Geo- 

 graphical Society (see fig. 35) ; it measuring about 20 miles across 

 the front. Deeply penetrating the coast Between Boger Point and 

 Clarence Head. Constable Makinson of the Royal Canadian Mounted 

 Police (see Annually. 1928) has recently discovered and mapped a 

 .spacious inlet (see fig. 34). Inside of Clarence Head, that is in a 

 northwesterly direction, the coastal foreland is low and covered with 

 several unnamed glaciers. The southern coast of Ellesmere Land, 

 forming the northern side of the 35-mile wide Jones Sound, is more 

 or less glaciated but few, if any. tongues extend to the sea except the

 in honor of the American Geogrtiphieal Society and located in latitude 77° 30' N.,

 some of the glaciers of west Greenland is negligible. (Photograph by D. B. Mac-

mere Land, accordinir to the foregoing survey, contains an estimated 

 total of about 60 tidewater glaciers. 



The extent of the Ellesmere Land ice caps with the number, size, 

 and rate of movement of its glaciers is an important question. It 

 would be very interesting to know, for example, whether or not 

 Ellesmere Land contributes materially to the supply of North At- 

 lantic icebergs, and also in Avhat proportions. The fact that the 

 eastern coast of this island is located at the northern end of the 

 great ice stream to lower latitudes, offers any icebergs that are dis- 

 charged there a direct route for 1,700 miles downstieam to the 

 Grand Bank. Little or nothing has ever been published on the ice- 

 berg productivity of Ellesmere Land. MacMillan who followed the
