both sides of Waagsfiord is towards the south-east, but at Waag there is a hollow 
which runs from the head of the fiord south-west to the open sea coast, along 
which a stream of ice has flowed, as is shown by roches moutonnées and strize 
pointing S.W. At Famdye, likewise, we got evidence of an ice-flow to the west 
—striz and roches moutonnées on the south side of the bay pointing distinctly 
in that direction. 
I have some additional remarks to make upon the subject of glaciation, but 
these I shall defer to a subsequent paragraph. 
3. Till or Boulder-clay—tThe till or boulder-clay of the Feerée Islands closely 
resembles the similar deposit which occurs in the hilly and mountainous districts 
of Scotland. We found it in a great many places, generally as little local 
patches, sheltering in the lee of voches moutonnées and projecting rocks; at 
other times spreading more continuously over low ground, and covering the 
beds of gently-sloping and wide valleys. Not infrequently it occurs along 
the margins of fiords, where the hills retire, and the coast-land is low. It 
varies much in thickness, but seldom exceeds 15 feet, and generally it is much 
thinner. In the neighbourhood of Thorshavn, it is a hard, tough, dark brown 
deposit, stuck full of blunted stones and boulders, some of which were well- 
striated. This was the case especially with some of the bigger stones. The 
same deposit of till showed here and there an irregular layer of earthy gravel of 
the usual character. The clay ranged in thickness from a few feet up to six 
yards ; and here and there contained blocks of basalt that measured 10 and 12 
feet across. Along the shores of the bay it rests upon a glaciated surface, and 
the same is the case with the till at Héyviig, which is of a dark brownish blue 
colour. I noticed till also in Kolfaredal and at Westmannshavn and Saxen. 
Thin sprinklings were observed at various places between Eide and the foot of 
Slattaretind ; and at Andafiord the low cliffs along the shore are formed of a 
very hard, dark greyish blue till with angular and blunted stones—some of the 
larger ones showing striz. This till rests on a striated surface of dolerite. 
Another good exposure of till occurs on the shores of Bordevig fiord, close 
to Klaksvig. It contains intercalated lenticular beds of fine tough brown stone- 
less, laminated clay and sand, as shown in Plate XV. fig. 19. The till is of the 
usual character, but very few of the included stones show faint striz ; they are 
of the common blunted subangular shape. At Gidthe there is a good deal of 
till, and irregular sheets of it appear here and there along the course of Skaale- 
fiord, as at Siov, Strendre, and Glibre. Again in Sandée considerable depths 
of till fill the bottom of the valley that opens into the sea at Sand. The deposit 
in this valley is more than 20 feet thick, and is well exposed along the course 
of the stream. We noticed till in Suderée in many places, but more particularly 
in Trangjisvaag valley, and at Ordevig. In the former it occupies the whole 
bottom of the valley, and it also shows in various places along the northern
