general relations of the quartzite, limestone and schists to each 

 other that is attempted. 



To the west of the Taconic Range the section passes down 

 through the limestone (3) to the hydromica schists (2), and 

 thence to the great development of slates and shales with their 

 interbedded sparry limestones, calciferous and arenaceous strata, 

 all of which contain more or less of the Olenellus or Middle 

 Cambrian fauna.* 



No. 2 occupies the stratigraphic position of the Potsdam for- 

 mation elsewhere ; and 5 and 6a by contained fauna and strati- 

 graphic relations, are correlated with the Granular Quartz 

 series (1) and referred to the horizon of the Middle Cambrian, 

 as the latter is defined in Bulletin 80, U. S. Geological Survey, 

 and in the table of classification {ante). 



Between the limestone (3) and the slates (5) there are several 

 displacements, but none to displace the strata sufficiently to 

 bring rocks of other formations in sight, and so break the sec- 

 tion that the general relations of 3, 2 and 5 can be interpreted 

 by me in a different manner from that given in the section. 



Art. XXXIV.— Terminal Moraines in North Germany ' by 

 Professor R. D. Salisbury, of Beloit, Wisconsin. 



During the past summer some observations have been made 

 upon the drift formations of northern Germany which may 

 not be without interest to the students of Quaternary Geology 

 in America. It is the writer's expectation to continue the 

 same line of study next season. It is due toPresident T. C. 

 Chamber lin, who has done so much for Quaternary Geology in 

 America, to say that the study of the drift phenomena of the 

 above specified region was undertaken at his suggestion, and 

 that he had forecast with surprising accuracy, the results which 

 observation has confirmed. 



So far as the work has been prosecuted, attention has been 

 mainly directed to a terminal moraine, or, more exactly, to a 

 terminal morainic belt, which crosses Germany, and which has 

 been traced in more or less detail from Denmark to the Rus- 

 sian border. In the tracing of this belt, the main reliance has 

 been upon topography, which here, as in America, affords the 

 most reliable and the most available single criterion for the de- 

 termination of the formation. 



So striking is the topography throughout the greater part of 

 the course of the moraine in Germany, that it could not fail to
