On previous occasion (Geol. Mag., Dec. V, Vol. IV, 1907, pp. 17–20) an account was given by the author of lornagnt Strand in the estuary of the River Suir; and the nature anddevelopment of the drift deposits further up the river may now be described.

On the north side of Knockavelish Head (which bounds Fornaght Strand on the north), the coastfrom Ballyglan is bordered by low sand dunes for a distance of about a mile and a half, and thereis no cliff or exposure of any solid rock, the old sea margin being apparently situated now some way inland behind an area of more or less marshy laud at the back of the dunes. Traces of the former sea-cliff can, however, be recognised here and there by a sudden slight rise in the ground. A wide flat expanse of sand and mud, known as Woodstown Strand, is uncovered at low tide along this stretch of coast, extending out fully a mile from high-water mark, but so far no trace of the submerged forest of Fornaght has been here discovered.
