THE SAND-DUNES OF THE LITTORAL 



A STUDY of the conformation of the east coast of 

 Africa reveals a curious repetition of outline. It 

 is a succession of bulges and bights, shrinking 

 in dimensions as we proceed southwards. From 

 Cape Guardafui one great westward sweep culmi- 

 nates at Saandani, opposite Zanzibar. From there 

 the coast curves boldly outwards to Mozambique, 

 and then gives again to Sofala. At Inhambane 

 and Delagoa Bay, St. Lucia Bay and the Tugela, 

 the bulge and bight are twice again repeated, and 

 then disappear. This coincidence of contour in 

 so far as the Province of Mozambique is con- 

 cerned is, I think, capable of explanation by a 

 study of the effects of the natural forces now 

 at work, and which have been at work doubt- 

 less for ages past. 



The great rivers of the Province have, of course, 

 been important instruments of architecture, and 

 have built themselves enormous alluvial plains 

 through which they now flow with leisurely
