GARNET SECTION. 
Garner. Occurs disseminated through gneiss and mica-schist in the 8.E. 
part of the county, especially at Golard* and Ballykillowen*, parish of Tem- 
plecarne ; at Aghadoey*, it occurs in the gneiss in such quantities as to form 
garnet-rock. Clear varieties occur in granite at Shallogan Bridge, and on the 
south side of the Guibarra valley; in the Poison Glen; at Tirlyn and Kil- 
loughecarran, near Creeshlagh; and in limestone at Aphort, Arranmore*. 
Opake varieties occur, with hair-brown idocrase, epidote, and tremolite, in 
crystalline limestone in many places, e.g. Glenleheen*; Derryloaghan ; 
Toberkeen*, near Dungloe ; Annagary*; Lough Anure* ; Bunbeg* ; Barnes- 
beg Gap*, near Kilmacrenan; Tirlyn. 
At Toberkeen, loose crystals, many of them pitted and worn by the action 
of the sea-water, are found on the beach. They are frequently 2 inches or 
more in diameter. 
Cinnamon-stone.~At Trawenagh Bar. 
Grossular.—At Annagary*; at Bunbeg. 
Ipocrast. The bacillar variety occurs in limestone at most of the localities 
above mentioned for opaque garnets ; also at Madavagh, near Lettermacaward. 
On the promontory, at the north end of Lough Anure*, it is found in four- 
sided crystals; also at Toberkeen. 
Eriporz. Occurs pretty commonly, with garnet and idocrase, in the altered 
limestone. At Drumnaha, Glenleheen*, it is found well crystallized; at 
Aphort*, Arranmore, in great abundance ; in gneiss close to the limestone at 
Pollnacally* ; Crohy, in a vein in syenite ; at Woodquarter, parish of Mevagh ;
