326 A. C. Ramsay on the Glacial origin of certain Lakes 
frost, ice, rain, and rivers, probably ever since the close of the 
Miocene period. In the valley of Oberweiler, between Mull- 
heim and the watershed, | observed occasional heaps of moraine- 
like detritus, in which by diligent searching I found a few stones 
marked with the familiar glacial scratchings. 
In the interior towards Schonau and the Belchen, the rocks 
glaciers occur, and no part of the country shows symptoms of 
the presence of drift. Altogether, the country looks as if it had 
in the air for so great a period that, even if glaciers were 
once present, they had disappeared so long ago that all the more 
prominent signs of degradation are now due to rain and running 
water. But further in the interior it is altogether different; for 
the signs of old glacier-ice are plentiful enough, and for miles 
round the Feldberg, which rises 4982 Baden feet above the sea, 
the sides of the valleys to the very summits of the mountains 
are often strikingly moutonnées, though the rounded forms are 
generally roughened and frequently half ruined with age. On 
these, striations, though rare, may occasionally be discovered 
(running in the direction of the valleys), although the rapid rate 
at which the rock weathers is much against their preservation. 
Moraines also are not uncommon. At the foot of the Feldberg, 
on the east, there is a beautiful circular lake, called the Feldsee, 
surrounded by tall cliffs of gneiss and granite in the shape 
known in Scotland as a corrie—a form eminently chara 
of all glacier-countries past or present. The outer side of the 
lake is dammed up by a perfectly symmetrical moraine, curvi2g 
across the valley, and formed of sand, gravel, and i 
and gneiss, often in large boulders. It is now cove as 
pine-trees, The lake is deep, and the moraine rises from 26 
40 feet above the water. Outside the moraine lies a flat mars" 
still retaining traces of having been a lake, once also damm 
by a second and outer moraine, formed chiefly of large aren id 
blocks of gneiss, piled irregularly on each other like the ol¢ 
moraine 0 Boulidseve, above Llyn Ogwen in Caernary x 
shire. Quantities of moraine-matter strew the valley for id 
three miles further down to the little marshy lake at Waldbauer, 
which is also dammed up by moraine-rubbish, in one PU
