 who have used them say that "they are the best in Ireland."

DONEGAL. 



Potter's Clay occurs on Arran Islands, in the Bosses, in Tory 

 Island, and at Drumarda on Lough Swilly ; it has been used a 

 little in the manufacture of coarse pottery. Pipe-clay is found 

 frequently, but little used. Dr. Parland in his Statistical Survey, 

 1801, called attention to the pipe- and brick-clays in Drumarda. 

 At that time the natives of Tory " made clay-pots, in which they 

 boiled potatoes or anything else." 



Bricks are made at Moy, two miles from Ballyshannon, but 

 they are unshapely, 8s. to 12s. per 1000 ; a few are made near 

 Donegal. They are also made at Milk Island, near Letterkenny, 

 and at Ramelton, from the clay of the " isles " or flats margining 

 Lough Swilly ; at Drumskillin, in Inishowen, 9 x 4| x 3, weight 

 5 \ lbs.; Strawbridge, very inferior quality; Burnfoot railway 

 station, 20s. per 1000, also draining and other tiles ; and Ardnaree, 

 five miles from Millfort, 18s. per 1000, 9£ x 4| x 3f, weight 8 lbs. 



In the blue brick clay margining Lough Swilly, about a mile 

 eastward of Ramelton, Mr. Mahony found a fossil deer's horn. 



DOWN. 



In Ballymacarret, the eastern suburbs of Belfast, there were 

 china and delft works for many years; whence the clay, &c, was 

 procured we were unable to learn. (See Belfast, ante, p. 148.) 



Yery good Brick-clay occurs near Banbridge, from which red 

 but not well-made bricks are manufactured ; but a first-rate brick 

 could be made from the clay, 25s. to 28s. per 1000, 9 x 4 x 2| ; 

 inferior bricks are made at Doionpatrick ; red at Kilkeel, 20s. to 

 25s. per 1000, 8J x 4 x 3, weight 6| lbs. ; small red bricks at 

 Rostrevor; in different places in the neighbourhood of Newry, 

 20s. to 24s. per 1000, 8| x 4± x 2f , weight 6J to 7 lbs, and very 

 inferior at Newtownards. There is good brick-clay near Porta- 

 down, and extensively wrought. 



Hard red bricks are made from the clay of the boulder drift 

 west of Waringstown. This clay also occurs in cuttings along the
