(p. 98.) — ''A dyke of fine dolerite reaching 4 yards in width, 

 passes hy Lough Aninver on the mainland north of Gweedore Bay. 

 It is in some parts porphyvitic with large crystals of felspar." 



" Two separate rocks, rising from the sea, in nearly the same line 

 and distinguished hy theii' dark colour, are prolongations of this dyke. 



" Tori/ Island. — Tory Island in the Atlantic Ocean, is situated due 

 north of the coast of county Donegal. It is ahout eight miles distant 

 from the foreland, and lies a little to the east of north from that head- 

 land. The distance from the hoat slip at Magheraroarty is nine miles, 

 and from Dunfanaghy, around Horn Head to the same part of the 

 Island, ahout 16 miles. The Islands of Inishbofin, Inishdooey and 

 luishbeg lie between Tory Island and the mainland, the farthest north, 

 viz. Inishbeg, being about half-way across. 



" The Island of Tory is a naiTow strip of rocky land lying with 

 its longest diameter of nearly three miles in a north west and south- 

 east direction." 



(p. 99.) — " At its widest part, viz. at the north west extremity, 

 it is less than a mile in width, and at the narrowest part, i.e. just east 

 of "Westown, or about the middle of the Island, it is only one-fifth of 

 a mile across, its average breadth being about half a-mile. 



"The natives always speak of it as Tor-i, and this would appear 

 to be the most explicit manner of spelling, to be in consonance with 

 the derivation of the name. 



" This island was anciently the stronghold of the Formoriau 

 pirates, whose chief was Balor, ' and two of the tower-like rocks on the 

 side of Tory are still called " Baler's Castle " and "Baler's Prison"' 

 Of the former of these, there remains but the site. As it was situated 

 at a very narrow isthmus which is the only passage from the main 

 portion of the island on to the Doon peninsula (where peat is cut for 

 fuel), it is probable that the islanders have removed the building. 

 The highest point on the island, viz. Doon Balor, 282 feet above sea 

 level, is situated at the north end of this peninsula and in the cliffs 

 further south, was ' Balor's Eort,' Around Westown are several not 

 too well preserved monuments of ancient worship — as St. Columbkille's 

 Church, St. John's altar and cross, another altar, a grave. Temple 

 Anvoresher, or Church of the Seven, and a Cloigtheach, or round tower. 

 This latter is the only one that is well-marked and preserved."

 although very miich broken and irregular, presents a general inclination
