456 THE ICE AGE IN NORTH AMERICA. 



During the summer of 1888 Professor Salisbury, who 

 had been for several years associated with President Chain- 

 berlin in the glacial survey of the Northwestern States and 

 Territories, made also a hasty survey of northern Germany 

 for the purpose of correlating the glacial deposits of that 

 country with those in America. The results were most im- 

 portant and interesting.* He found a double series of termi- 

 nal moraines back some distance from the extreme glaciated 

 limits, as in the Northwestern States of America, and resem- 

 bling them both in their composition and in their situation 

 with reference to the marginal deposits. As traced by Pro- 

 fessor Salisbury, this belt of moraines follows approximately 

 the curve of the south shore of the Baltic Sea, and not many 

 miles from it. Its course lies through Schleswig-Holstein, 

 Mecklenburg, Potsdam (about forty miles north of Berlin), 

 thence swinging more to the north, and following nearly the 

 line between Pomerania and West Prussia, crossing the Vis- 

 tula about twenty miles south of Dantzic, thence easterly to 

 the Spirding See, near the boundary of Poland. 



Among the places where this moraine can be best seen 

 are — " 1. In Province Holstein, the region about (especially 

 north of) Eutin ; 2. Province Mecklenburg, north of Crivitz, 

 and between Biitow and Kropelin ; 3. Province Brandenburg, 

 south of Keckatel, between Strassen and Barenbusch, south 

 of Fiirstenberg and north of Everswalde, and between Pyritz 

 and Sol den ; 4. Province Posen, east of Locknitz, and at 

 numerous points to the south, and especially about Falkenburg, 

 and between Lompelburg and Barwalde. This is one of the 

 best localities. 5. Province West Preussen, east of Biitow ; 

 6. Province Ost Preussen, between Horn and Widikin." 



Comparing these with the moraines of America, Professor 

 Salisbury remarks : 



In its composition from several members, in its variety of 

 development, in its topographic relations, in its topography, in
