the east coast of th«- island. As already stated (p. 1«\ the origmul 

 surface of this steep slope i.s covered for the most part by later 

 lavas and éjecta, being protected from marine abrasion, while only 

 at the part where the 170 ;/?. cliff is now developed could no 

 covering of later materials be seen. This part, then, must liave 

 been subjected to marine action for a long time and the high chff 

 must have consequently been formed. The steepness of the original 

 slope may also have favoured the development of this high cliff. 



The action of tlie weaves has clearly been far more vigoro'.is 

 than the dissecting action of streams, for at every point whero 

 a valley ends it hangs high on the sea cliff. The sole, more or 

 less permanent stream in Oshima near the eastern shore flows down 

 into the sea over a hansing vallev in a water-fall called Funo 

 no Taki'^ (3c ; Fig. 30).
