The recent development of mining in the central area of the Ballycastle Coalfield in Co. Antrim has given rise to several articles in the daily Press, and it seems worth while to point out that the occurrence of coal-seams in the interior of the field was long ago proved by borings (see Geological Survey Memoir to Sheets 7 and 8, Ireland, published in 1888); while Mr. Symes's longitudinal section, Sheet 30, published by the Geological Survey of the United Kingdom in 1890, indicated faithfully the geological conditions. The possibility of farther development is also mentioned in “Ireland, Industrial and Agricultural,” published by the Department of Agriculture for Ireland in 1901.
