served muiu'iou.s snuill pntclies of till, often with well striated 
:stones; and luniicrous stones and much isolated debris occurred 
scattered over the surface in such a way that tiiey must have been 
swept away very ([uickly by the waves from the Athintic if they 
were ever suljnieroed. 
The reuuirkabh' overturned boulder which professoi- Shaler de- 
scribes on the southern summit of .Jordan's hill at an elevation 
of more tiian oOO feet does not seem in itself a surticient proof of 
ice-shove from Xhv sea and thus of submergence up to this level, 
as we cannot safely deny the possiljility that it might have been 
overturned by the roots of a tree in a vioh'ut storm or even by 
the agency of man. 
At the road on the southeast si(U' of ••the cleft, ' it looks as if 
the rocks had l)een swept bare ])y the sea up to al)out 200 feet, 
but we could not stop to ascertain with the liandlevel whetluM' this 
had be(!n the case. 
I stayed for a few days more to make further attempts in de- 
termining the marine limit. 
About one and a half miles south of l>ar Harbor, at the soutii- 
ern end of the 2S0 foot hill. 1 found a cut terrace, above whicli I 
Could find nothing but angular stones, while on a level a few feet 
lower watervvorn gravel and pebbles were plentiful, as on the top 
of the roadhill. Here, as in other places on the island at a some- 
W'hat lowej' level, the gravi'l oveilapjjed the clay, having been 
brought into this position as shore drift during tJu' successive 
tiphetivals of the land. The hight of the marine limit at this 
point as far as it could lie ascertained was about 20!) feet (c, 
<)4 m. ). 
About one mile southwest of liar Harl)oi' an<l on<' mile K. N. K. 
of the northern end of Kagle lake, just al)Ove the covering of 
marine sedinu'iit. I founil a little series of well develo|)ed beaches, 
of which the uppermost and largest, marked by a gravel pit, was 
situated according to tlie liMi'ometer :it a hight of :iliout 21 feet 
(c. (i4 m.). 
Finally 1 returned to the above nuMitioned point N. \\. of Somes 
sound, where I first ot)served the marine limit, and made a more 
(•areful investigation. I followed the shore-line with a hand- 
level for nearly half a mile north of the road, finding the follow- 
ing dilferenccs. the al)solute higiit being measured witii a barom-
