Northward from this halt the ice, so far as the drift in the valley | 
affords evidence, suffered a more rapid retreat. At any rate, no ' 
well-developed loops cross the valley; nevertheless both walls 
suggest a less rapid retreat of the ice in that they are fairly well 
mantled with irregularly distributed drift. Having in mind that : 
the retreating ice in the region of the lakes constantly held in I 
front of it, through several degrees of latitude, static bodies of 
water into which streams from the well dissected lands were pour- j 
ing their load of gravel, sand and silt, and the further fact that j 
the later ice-front lakes were of longer duration than the earlier |; 
ones, and consequently spread over their bottoms a greater i| 
amountof lake deposits, it is to be expected that mild loops, formed j 
with the slight halts of the ice, have been largely obliterated. A 1' 
long duration of such a series of factors would tend to efface the |l 
evidence of loops that formerly existed in this segment of the j| 
Freeville-Moravia valley. Furthermore, it is probable that the 
frontal parts of these loops were largely disseminated through the 
static water into which the loops were being deposited. 
(2) In Fall Creek Valley. It is recalled from thediscussion ji 
under drainage that the most mature topography of the Moravia 
quadrangle is found in, and adjacent to, the Fall Creek valley, j 
We recall also the fact that at McLean this Fall Creek valley, j 
as marked on the Moravia sheet, joins a master valley extending : 
southwestward towards Ithaca. The maturity of development 
found in both the master stream and the tributary have tended 
to produce, during the retreating stages of the glacier, a more |: 
evenly outlined form of ice-lobe; the gently rising side walls and j| 
the preglacial width of the valley bottom give us here quite a j| 
different type of loop than that described in the Freeville-Moravia 1' 
valley. 
‘‘J.” In passing north and east from Freeville along the || 
Lehigh Valley Railroad one notes in the vic’nity of Red Mill the | 
converging, toward the valley-bottom, of the massive kame accu- jl 
mulations, particularly those on the eastern side of the valley. |j 
A short distance north from this place, at Malloryville, the valley }j 
becomes quite completely clogged with glacial debris. The ji 
typical developed esker (fig. 18) described elsewhere in this paper j, 
is found at this place. Kettle holes and other phenomena espe- j! 
cially characteristic of washed drift are numerous. The present ; 
stream has sluggishly picked its way through the massive accumu- j
