controlled by governing lateral rock walls. There is an old physio- 
graphic term long used by the Scotch and which the writer has 
applied on this side the Atlantic, namely, the word “goe” which 
means the place left on a sea coast through the removal by wave 
action of a prism of rock originally bounded by more or less vertical 
joint planes. The creation of such prismatic retreats and endroits 
on a coast gives it a peculiarly hatched aspect and often when carried 
to extreme, results in the creation of a natural bridge or a sea gully 
which may run through a projecting peninsular head from one side 
to the other. Such goes are common in the north of Scotland and 
in the Orkney Islands. They are also beautifully represented on the 
shore of the Forillon in Gaspé, where their place is taken by short 
crescentic beaches. On the south shore of Isle-au-Haut there are 
places at Western Head and the coves adjoining it, where the approxi- 
mately north-south direction of the joint planes has permitted the sea 
to knock out rock prisms, leaving behind little retreats with sharply 
vertical rock walls and often a beach in which the small pebbles have 
been symmetrically rounded, the result being the same and due to 
the same causes as more extensively and emphatically expressed at 
Boom Beach. The illustrations accompanying this note show very 
effectively the results of this sort of sea milling.
