LONDONDERRY. In this county rail ways are in progress from Londonderry to En niskillen, and from Londonderry to Coleraine. A remarkable feature of the last-named scheme is, that the railway is to cross Loch Foyle on an embankment 10 miles long, as a means of inclosing and reclaiming 18,000 acres of land. The best improved portions of the county are the district of Loch Neagh, the valley of the Roe, the valley of the Faughan, and the immediate vicinity of Londonderry on both sides of the Foyle. There is a very gene ral scarcity of timber. The progress of agri culture in this county has been materially forwarded by the establishment of an agricul tural school near Muff by the Company of Grocers of London, who here hold large estates under the crown. Oats and barley are the principal grain crops.
The manufacture and bleaching of linens is the staple trade of the county. The most ex tensive bleach-greens lie along the rivers Roe and Faughan, on the latter of which there is abundant water-power and numerous sites admirably calculated for this branch of ma nufacture. The weavers and flax-dressers are numerous. The export and import trade of the county is carried on at the ports of Lon donderry city and Portrush, the latter being the seaport of Coleraine.
