sides. That there was some horizontal movement together with 

 a slight vertical displacement is also shown by the neighbor- 

 ing faults. The cliff beds are much more fractured here than 

 they are in the region immediately east, which is that shown in 

 plate I. As a result the cliff face has here receded to .the north 

 more rapidly and has left the less fractured face some meters 

 behind.. The latter plunges vertically into the water but the 

 more rapidly receding portion has left in front of it a sloping 

 beach which crosses the cave mouth at the cliff line. This re- 

 cession and the position of the cave, which is well within the 

 bay, both protect it somewhat from the effects of freezing spray 

 though we still have the active work of freezing of water after 

 cold rains in fall and spring and the freezing of water from 

 melting snows. During storms the strong elbow of the cliff 

 protects the recess from the grinding effects of strong wave 

 action, and the fragments on the floor are but little rounded. 

 Probably the fragments now on this shelf are comparatively 

 new, for oblique wave motion would carry the more worn ma- 

 terial into the recess at the northwest corner of the bay. Here we 

 do find a mass of material that is all of limestone and has accumu- 

 lated in this locality since glacial time. The writer first saw this 

 cave in 1898. The following year he camped in its vicinity and con- 

 verted it into a very serviceable dark room for photographic pur- 

 poses. One large and well worn stone lay partially within the 

 mouth and this was removed to make the interior easier of access. 

 One had still to enter on hands and knees, though after penetrating 

 to the horizontal depth of about 2 meters, one entered a rather 

 roomy chamber in which several people could stand at the same 

 time. The roof of this chamber is about 3 meters above the 

 floor. Back of this first chamber there is another but the pas- 

 sage between the two is too narrow to allow of entrance. A few 

 blocks were carried into the first chamber to support a board 

 which was used as a dark room table. The waves of the follow- 

 ing season moved several large blocks against the opening of 

 the cave but did not disturb the stones placed on the floor of the 

 chamber. For several years blocks have been thrown up in the 

 front of the mouth during spring storms and often one or more 

 has had to be moved in order to gain access to the in- 

 terior. No large blocks have ever entered to any great distance 

 into the cave. Waves have no doubt thrown smaller wave- 

 worn pebbles over the larger guarding blocks and have 

 moved these back and forth at exceptional times, but such
