Abstract
THE Seychelles Archipelago is situated in the Indian Ocean some 1,100 miles to the east of Mombasa. It is made up of nineteen islands and a number of islets of which all but two are granitic in composition. The only two coral islands in the group are Bird and Denis, which lie at a distance of about sixty miles north of Victoria, Mahé. Mahé itself is the largest of the islands, being seventeen miles long and up to seven miles wide. Rugged peaks of granite rise to a height of almost 3,000 ft. above sea-level and show marked erosion features. Praslin, Silhouette and Digue are the other main granitic islands of the group.
