“The inhabitants of the county are chiefly employed in agriculture and in the fisheries. The salmon fishery of the Moy and other streams is an important branch of industry, and on the coast ling, sole, turbot, herring, cod, oysters, lobsters, and seals, are taken. Greater attention is paid to pasturage and the rearing of cattle than to agriculture, which is in a backward state. The arable soils are mostly fertile, and much enriched by plentiful manurings of sea-weed. The cotton trade has greatly declined of late years, but there are still some manufacturers, chiefly at Ballyclare, who produce goods for domestic use” [Description from The National Gazetteer of Great Britain and Ireland (1868)]Transcribed by Colin Hinson ©2018]

“Owing to the scarcity of wood, the peasants occupy huts of a wretched description. The farm labourer is paid at the rate of about 8d. a day, without rations of any kind.’ [Description from The National Gazetteer of Great Britain and Ireland (1868)]Transcribed by Colin Hinson ©2018]
