near by rise to 1,400 i'eet or over. This is the top of the 
country and affords a grand view all around. One looks away 
east and south over the tops of many hills that rise almost to 
the same level, forming apparently an ancient peneplain. Be- 
tween the hills are deep valleys of ten wide, holding many lakes 
and streams that flow eastward with moderate descent. To- 
wards the northeast the hills of Quebec; north of the Ottawa 
river were seen clearly. 
At Deux Rivieres, 22 miles east of Mattawa, another effort 
was made to find high shore lines. Almost the whole distance 
of eight miles south to Stony hill was over what are locally 
called " the plains " but which proved to be a great area of 
karaes. This kame deposit is composed almost entirely of 
yellow sand too coarse to be blown by the wind. Deux Rivieres 
has an altitude of 520 feet above sea level (C. P. R. profile) 
and the limit of the sands was not reached on Stony hill at 
an altitude of about 1,210 feet. Upon this slope of over 700 
feet in something less than eight miles the deposit is spread 
in characteristic kame fashion. In some parts the knob-and- 
basin topography is well developed. Other parts are billowy 
and others more nearly a plain. There are also some high, 
rather irregular ridges. Some of the kettles are 50 to 75 feet 
deep. All that were seen were dry, but there are a few lakes 
in the larger basins. About six miles out the road passes in 
view of Green lake along its west side. This lake is perhaps 
half a mile long and nearly as wide and is approximately 450 
feet above the station (970 feet above sea level). In the cen- 
tral and lower part of the area the stony ground moraine sel- 
dom protrudes through the sand. But towards the south in 
the higher part of the area stony drift surfaces are common. 
The sand appeared to thin out in that direction and occurs 
there in patches. At an altitude of about 1,130 feet a distinct 
terrace about 800 to 400 feet wide was found facing north or 
slightly west of north. This shelf sloped from back to front 
ten or twelve feet and had a few bowlders scattered over its 
surface. The bluff at its back is high but not steep. The 
bench was followed to the east,where it fades away on a steeper 
slope, but no certain evidence of wave work was found — noth- 
ing resembling a beach ridge nor a spit nor did the bluff seem 
quite like one cut by wave action. It is not (niite certain that
