WIA, an isle, in the parish of South-Uist, county
of Inverness. It lies on the south-east of the island of
Benbecula, from which it is separated by a very narrow
channel called the Sound of Wia, where is a small and
safe harbour. The isle is about two miles in length and
one mile and a quarter in breadth, and is much indented
on every side. Its rocks, like those of nearly all the
islands in this quarter, are wholly gneiss.
