the new maps. In every place known to me, many are omitted. Eoughly 

 speaking, there is a fort to about every 317 acres of land; this is regarded by 

 some as important, but means little, as the distribution is most variable. 



EiNG-FofiTS. — As to their size, the largest is the great ring, mounds and 

 wet fosse, in which Oloncagh Church stands.^ The enclosure is 750 feet to 

 770 feet across, and has a well in the garth and two near it (O.S. map 37). 

 Several forts from 450 feet to 400 feet remain — Eathanny, 450 feet, with a 

 small central mound and two outer rings (40); Dun Clare, 450 feet to 

 400 feet (49) Ballykinnaugh, 420 feet by 300 feet (47) ; Croaghane, near 

 Foynes, now levelled, was 470 feet across east and west, and 390 feet north 

 and south (lo). The following are about 400 feet across : — Kilmacat (4) ; 

 Ballinscaula (40); Portauns, a D-shaped fort (47) ; Greenish Island (10); 

 Killeen, near Springfield (54) ; Dromin, or Gortroe (36) ; Boheyglela (30). 



Forts 350 feet to 300 feet in diameter — Graige, oval, 350 feet to 

 250 feet (38) ; Ballinscaula, 350 feet, with small central mound (40) ; More- 

 nane, shield-shaped fort (36) ; Cottage, of two rings (40) ; Tullymacthomas (45) ; 

 Crean (31); Dunganville (28); and Glenma (39). 



Forts 300 feet to 350 feet across — Feohanagh, D-shaped (45) ; Lotteragh, 

 near the castle (45) ; Coolrus (36) ; and the long oval fort of Toberyquin. 



Forts 250 feet across— Lisduff in Gardeufield (54) ; Shanid, Lower (19) ; 

 Garranroe (21) ; Lisnagilla (28); Crean (31); Ballyclough, two forts (38); 

 Ballylinan (44) ; Eathcahill (44) ; Kilballymartin in Mundellihy (45). Lastly, 

 those 200 feet in diameter are— Cloucriffa (45) ; Arnacrohy (36); Clogher (39); 

 Ballyagran (40) ; Mount Blakeny (47). The rest are usually about 100 feet 

 across, or from 60 feet to 150 feet ; some mere house rings, 40 feet to 50 feet 

 across. 



Conjoined Forts. — Forts of this curious type, like theForrach and Teach 

 Cormaic at Tara, are scarce in Co. Clare, but abound in Co. Limerick. This 

 is merely a tentative list — Cloughkeating (13) ; Griston East (49) ; Incha- 

 comb (57); Boherygella (31); Eaheenamadra (41); Knockauuaskeagh or 

 Garrankeagh (47) ; Baunteen (59) ; Ballynemore (59) ; Ballinscoola, two 

 very close, but not joined (32) ; Clogher East, two conjoined and two very 

 close (39) ; Ballykenny, two conjoined forts and an irregular fort with a 

 D-shaped annexe (44) ; three are conjoined at Doonainy, on Knockaney 

 Hill (31), Doonakemna, not in line (35), and Cush near Kilfinnane (48). 

 The last (as we shall see in a later section) is a really remarkable group of 

 eleven small forts between Glounacroghery Glen and Kilmurry Bridge near 

 Moorestown.
