NOOTKA SOUND, an inlet of British North America, on the W. coast of Vancouver Island; N. Lat. 49. 35., W. Long. 126. 35. It stretches in a N.N.E. direction for 10 miles, and forms a number of smaller bays and coves. There is a wooded island in the centre; and the greatest breadth of water is not more than a quarter of a mile. The shores are rocky, and the bay forms a very safe harbour, but is not capable of accommodating more than two vessels.
