406 R. D. Salisbury — Terminal Moraines in Germany. 



relations, in its topography, in its constitution, in its associated 

 deposits, and in its wide separation from the ontermost drift 

 limit, this morainic belt corresponds to the extensive morainic 

 belt of America which extends from Dakota to the Atlantic 

 Ocean. That the one formation corresponds to the other does 

 not admit of doubt. In all essential characteristics they are 

 identical in character. "What may be their relations in time 

 remains to be determined. 



It is not improbable that the outer and inner members of 

 this series, where widely separated geographically, are also 

 somewhat widely separated in time. The former frequently 

 show unmistakable signs of greater age. Where the geograph- 

 ical separation does not obtain, this difference is also wanting. 

 This relationship would be easily explained by supposing that, 

 where the range is single, the margin of the ice was as far 

 advanced at the time of the formation of the subsequent mo- 

 raines (or at least at the time of the last), as at the time of the 

 formation of the first, and that, where the moraine is two-fold 

 or -more, the ice failed at a corresponding number of moraine- 

 forming periods, to reach its earlier position. Analogous rela- 

 tionships were long since recognized in America. 



It may be fitting to mention a few localities where the 

 moraine may be seen in strongly typical development. Such 

 are (1) in province Holstein, the region about (especially north 

 of) Eutin ; (2) province Mecklenburg north of Crivitz and be- 

 tween Butow and Kropelin ; (3) province Brandenburg, south 

 of Reckatel, between Strassen and Barenbusch, south of 

 Furstenberg and north of Eberswalde, and between Pyritz and 

 Soldin ; (4) province Posen, east of Locknitz, and at numer- 

 ous 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 Windikin. 



The drift-covered area south of the indicated belt is not alto- 

 gether without moraines, and in this respect also the German 

 and American fields are similar. Furthermore, in Germany as 

 in America, these outer developments are less continuous, 

 partly because of subsequent erosion and partly because of 

 their originally weaker and more discontinuous character. 

 Detailed work will doubtless make it possible to show the con- 

 nections of these local (as they now appear) fragments, some 

 of which have but a limited development, while others may be 

 traced for considerable distances. 



Without mentioning more isolated occurrences of this kind, 

 reference may be made to certain morainic phenomena south 

 of Berlin, and which, though not consecutively traced, appear 

 to constitute for some distance a traceable, though quite unob-
