Examples almost equally as striking as those of Milforcl are to 

 be found in Smith's Sound and Hall's Arm. Preservation Inlet, 



Fig. 9. — General view of Milford Sound from convergence of 

 Cleddau and Arthur canons. 



The major thrust (P) has been directed against the right hand 

 (northern) wall, as shown by marvellously undercut walls, FF and 



QQ. 



A, Mitre Rock; 5,600 feet. 



B, Sterling Falls (Hanging Valley); 504 feet. 



C, The Lion Rock: 4,.300 feet. 



D, Sinbad Valley; 5,000 feet deep. 



E, The lip of Bowen Falls; 550 feet (caused by enormous 



undercutting of wall QQ). 

 FF, Straight wall; 2,500 feet high. Sound 1,500 feet deep 



under points FFB. 

 The Sound appears to have commenced by baisining near B, 

 and then carried backwards to ZZZ by recession of ice-fall and 

 marked canon-convergences. 



(Pl.xlv.) on the other hand, exhibits canon-divergence rather than 

 convergence. Here, then, one would naturally look for islets as 

 evidencing much reduced power of scouring.
