The third halt in the ice front shows that the recession was very 
unequal in different regions. In the eastern part of Germany the edge 
of the ice at this stage was far north of its position during the preced- 
ing stage, while in west Germany the differences in position were 
slight. Generally speaking, the border of the ice between the Weichse]l 
and the Oder, lay along the divide between the Netze on the south, 
and the drainage which flows directly to the Baltic on the north. It 
crossed the Oder near Oderberg ; thence it ran in a general northwest 
direction to Litbeck. From Ltibeck it extended north-northwest 
through Jutland. During this halt the edge of the ice had two or 
possibly three great lobes. The greatest of these lay between Danzig. 
on the east and Liibeck on the west. East of Danzig there was another 
lobe extending well southward, the eastern limit of which is not 
mapped. West of Liibeck the Jutland ice may be regarded as con- 
stituting a third lobe. Beside these great lobes, there were many 
minor crenations of the edge. This stationary position of the ice is the 
best known of all, partly because it has been more studied, and partly 
because it is far more distinct. All the criteria of the stationary edge 
find here their best development. The morainic (as that term is used 
in America) belt of this stage is the Baltic Hohenriicken. It is this 
belt which the reviewer traced out in a rough way in 1887, and char- 
acterized as the great terminal moraine of north Germany.’ Dr. Keil- 
hack says that this moraine is bordered throughout 650 of the 700 
kilometers of its length in Germany by sand plains. The morainic 
topography of this belt is much more strongly developed than that of 
the other halting places, as also the Hxdmordne. To Dr. Keilhack’s 
conclusion that the ice along the fourteenth part of this 700 kilometers 
where sand plants are absent, disappeared chiefly by evaporation 
instead of by melting, we can hardly subscribe. 
During this stage of the ice the marginal drainage was along the 
Thorn-Eberswalde Valley which connects with the Elbe southeast of 
Wittenberge. Along this course the water was partly fluviatile and 
partly lacustrine. 
The fourth and last chief halting place recognized is near the 
Baltic. In receding to this position from the last the ice retreated 
most over the lowest ground, and least over the highest. A new mar- 
ginal drainage line was formed not far from the coast, and roughly
