O'Reilly — On the Waste of the Coast of Ireland, 8fc. 165 



feet, although they are not so steep. Opposite the island of Illan- 

 master the cliffs are 790 feet high, and very precipitous. From thence 

 to Portui'lin they range in varying heights of 400 to 600 feet, with 

 islands detached from the several headlands and fissure gorges cut into 

 the mainland. Further westward the cliffs attain to still higher 

 elevations." 



(p. 8.) — "The Stags of Broad Haven form a group of four islands 

 rising from the surface of the Atlantic, at a distance of upwards of a 

 mile and a-half from the north-west coast of Mayo. One of these 

 rises to an elevation of 316 feet, another to 312 feet, the next to 

 256 feet, and the lowest to 243 feet. That nearest the coast is 

 domeshaped, while the most northern of the group is pointed. They 

 consist of schistose rocks, and form a favoiu'ite retreat for sea-birds." 



(p. 9.) — "The long north and south peninsula, locally called the 

 ' Mullet,' which is separated from the mainland by Blacksod Bay, 

 and an arm of Broad Haven, contains no very considerable elevations, 

 the highest (434 feet) being towards Erris Head on the north, whilst 

 the remainder of the peninsula is low lying and gently undulating 

 ground. The coastline from Eossport, along Broad Haven to Ems 

 Head and thence to Annagh Head, presents a continuous line of bold 

 precipitous cliffs, generally inaccessible, the remaining part being low, 

 gravelly, sandy, and rocky beaches." 



(p. 17.) — "Along the shore a Little to the eastward, between 

 ^yranagh and Claddaghnahowna, at the base of the cliffs 160 feet 

 high, the metamorphic rocks are visible at about the sea level, 

 dipping apparently 20°, 30° east-north-east beneath the Carboniferous 

 sandstones which overlie them unconformably, and dip from 5° to 10° 

 only. By the breaking away of the sandstones, owing to the sea 

 action, the schists are revealed at low tides, and in the face of the 

 cliff adjacent, their broken uneven surface is again visible underneath 

 the sandstones and shales." 



(p. 18.) — " At the head of the small bay, between Keady Point and 

 Benaderreen, into which the waves roll majestically, the incKned 

 face of rock is laid bare by the removal of the outer portion up to 

 a line of fault, which bears east-south-east, with an inclination 

 northward at 25° from the vertical, the southern side remaining 

 intact." 



(p. 22.) — " Peat logs. — Peat bogs are numerous and extensive 

 over the whole coxintiy, particularly in the southern portion, where 

 they are of vast extent and great thickness, and along the shores of 

 Blacksod Bay and Broad Haven, extend even below low-water mark.
