The same state of things prevails throughout the tract 

 southward as far as Sei-shi-an", the surface being covered with 

 thick ferruginous loam mixed up with Basaltic fragments, and 

 the upper and middle flows coming in direct contact, distinguish-

able only in the difference of structures. At the last-mentioned 

 locality, a ' haul-over ' of base-levelled middle flow, masked with 

 coral sand, separates the tongue of land Jiri-\ on which stands 

 a Basaltic, hat-shaped Bha-bü-sau"\ 47 m. high (Fig. 2). 



A good section may be seen along the shore, west of Jiri, 

 as is shown in Fig. 3. The columnar, upper (No. 1), and doleritic, 

 jjorous middle flows (Xo. 2), aggregating about 6 m., cap the 

 cliff, 20 feet high. That the two flows are separated by long 

 time intervals can be clearly shown elsewhere (Fig. 2) by a bed 

 inserted between them. I may cite the case of a lignite bed at 

 Baku, occurring in company with fuller's earth. Another instance 

 mav be given of it just east of Jiri, where an ash l)ed makes 

 its appearance. This ash bed is a fine, greyish-white, pulverent
