DONEGAL. This Irish county is rich in quarries of fine stone. The white marble of Dunlewy, near the mountain Erigal, is stated to be of an excellent quality, and its bed very extensive; it has been traced over a space of half a mile square, and is so finely granular, that it may be employed in the nicest works of sculpture. Its texture and whiteness; says Mr. Griffith, approach more to those of the Parian than of the Carrara marble. It is very well known that perfect blocks of the Carrara marble are procured with great difficulty, and I firmly believe that the marble of Dunlewyis free from mica, quartz grains, and other sub stances interfering with the chisel, which so frequently disappoint the artists who work upon the marble from Carrara.' A large sup ply of fine siliceous sand was formerly drawn from the mountain of Muckish by the glass-. houses of Belfast, and considerable quantities have been exported to Dumbarton for the ma nufacture of plate and crown glass.
The linen manufacture is carried on to a very considerable extent, and is increasing in the cultivated cottntry about Raphoe and Lif ford, and also in the neighbourhood of Bally shannon. Bleachgreens are numerous in the
neighbourhood of Stranorlar. Strabane, in the county of Tyrone, within two miles of Lif ford, is the principal linen market for the southern district. Londonderry and Letter kenny are the markets for the district to the north. Burning kelp continues to be a profit able occupation along the coast. About the beginning of the present century private dis tillation was carried on to an immense extent all over this county, particularly in the baronies of Inishowen and Kilmacrenan: repeated ba ronial fines and the vigilance of the authori ties have latterly checked the practice, but it still exists to some extent in the mountain districts. Considerable numbers of whales have from time to time been taken off this coast ; but this, as well as the herring fishery, is now neglected. In 1802 there were but two flour mills in this county. There was a few years back an export of 3000 to 4000 tons of corn annually from Letterkenny, and the re maining export of the county is from London deny ; but it has suffered in the recent gene ral depression of Ireland.
