284 The Irish Naturalist. 



Bay the Keenagli River was forded, south of which there is a 

 glorious pebble beach, dipping away down 20 feet to where 

 the waves were rushing up and down, rattling the pebbles 

 with a noise that could be heard a mile away. Behind the 

 beach rises an old sea-escarpment (perhaps made by a heavy 

 gale not long ago), cut out of an older beach, the top of which 

 is 20 feet above the present one. Behind the old beach the 

 ground rises in steep rocky ridges for several hundred feet. 

 At the southern end of the bay, high cliffs close in on the 

 strand, and soon I came to Stookanafanoga, a hugh sea- 

 stack of dark basalt rising in front of the grey quartzites. 

 There an ascent was necessary, and the route lay along high 

 headlands, whence the sun was watched setting in the western 

 ocean. In the dusk I crossed the sands which fringe the nar- 

 row and dangerous entrance to Trawbreaga Bay, and tramped 

 in the moonlight through Malin Town, and over the sleeping 

 country to Carndonagh. 



On the following morning I went eastward, and examined 

 for the raised beach underlying peat bog, which, according 

 to the Geological Survey, occupies the valley of the Culdaff 

 River, but very little was to be seen — possibly a pit would be 

 required to show the raised beach. Passing over a band of 

 black primitive limestone, Culdaff was left behind, and I 

 took road to Tremorne Bay, where I did not see the raised 

 beach marked on the Geological Survey map, though I looked 

 for it. Then on through the primitive hamlet 'of Ballyma- 

 garagh, and down the lyong Glen to meet the sea again at 

 Kinnagoe Bay, which is a most picturesque spot, with a wide 

 sandy beach, and high rocks, and steep slopes above. Here 

 I noticed a patch of stratified gravel at about 50 feet over 

 high water, in the bank of the road which leads down to the 

 shore, at the west end of the bay. It was full of fragments 

 of shells, too minutefor identification, and I got also one large 

 fragment of Pcdtmculiis, but I observed that behind the ad- 

 joining beach, on which Pcctunadus abounds, valves of this 

 shell and sand have been blown by gales up the slope to 

 quite as great an elevation, so possibly the Pectu7icuhis frag- 

 ment was not 171 situ. In the adjoining bay of Glennagiveny 

 is a well-marked raised beach at about 10 feet above high 

 water. In the banks of the little glen which runs into the bay 

 are stratified gravels at about 100 feet, containing a few
