LONDONDERRY. 



Potter's and Brick-clay along the Moyola river at Castle- 

 daivson, from which coarse pottery and bricks are made. In the 

 parishes of Aghadowey and Agivey, south of Coleraine, " a coarse 

 kind of earthenware, bricks, and water-pipes." (L. D.) 



Good Bricks within a mile and a-half of Coleraine, 12s. per 

 1000, 8 x 4 x 21. Muff, N. E. of Deny, very good bricks, 15s. 

 and 20s., 81 x 4^- x 2f . Ballyronan, three and a-half miles from 

 Magherafelt, bad bricks. Good in several places in the vicinity of 

 Limavady, 7s. to 9s. per 1000. 



" A few miles above Coleraine, on both sides of the Bann, is a 

 reddish or brownish brick-clay in many places, not much used at 

 present ; but it is used near Glasgort, and also about a mile west 

 of Coleraine, south of ' Irish Houses.' South of the Agency 

 bridge, the diatomaceous, or ' Bann Clay ' [Diatomite], is ex- 

 tensively used for brick-making." (F. W. Egan.) 



West of the Bann, and east of Ballynacree House, there is 

 brick-clay. Near Balnamore House a red laminated clay was 

 formerly manufactured into tiles ; while near Glasgort, S. W. of 

 Agivey, similar clay of reddish and bluish-grey colours is now 

 made into bricks, tiles, flower-pots, &c. — (g. s. m.) 



Below the peat at Littlebridge, near Castledawson, there is a 

 stiff brown clay, used for brick-making, while "Bann clay" is 

 found below the peat to the west of Church Island, as also further 

 north. — (g. s. m.)
