TOPOGRAPHY OF THE SAGAMI SEA. 11 



those ill tlie southern part of the Miura Peninsula, are made 

 use of, the two sets of lines serving as coordinates in fixing 

 the position of a given spot. The summits of Nokogiriyama, 

 Mineokayama and Tomisan (' Double Peak ') and Cape Dai- 

 busa, are all useful landmarks on the Awa side, but the most 

 important are furnished by Cape Mera and a range of adjoining 

 hills, which successively heave in sight beyond the steep brow 

 of Sunosaki as one sails outwards in a southerly or south-westerly 

 direction from Misaki. (See the woodcut on p. 15). On PI. 

 XIV, I have inserted a few of the lines of this series, based on 

 theodolitic observations which 1 myself have conducted at 

 Sunosaki against the different sight-marks concerned on the 

 promontory of Mera. Testing on several subsequent occasions 

 has shown the approximate accuracy of the lines. They are : 



1. ' Mera just out;' i.e., the line on which the extreme 



head of C. Mera is just visible beyond the brow of 

 C. Sunosaki. 



2. ' Jlera 1 ' (Jap.: Mera hitots) ; i.e., the line on which 



the first hill of Mera is completely in sight or the 

 first notch of the Mera ridge is in line with C. 

 Sunosaki. 



3. 'Mera 2' (Jap.: 3Iera futats) ; i.e., the second hill 



completely in sight. 



4. ' Mera 3 ' (Jap.: Mera mlts) ; i.e., the third hill com- 



pletely out. (See the woodcut on p. 15). 



5. MncMyama -e- C. Sunosaki. For the former, a conspicuous 



tree on the sky-line of the IMera hills serves for a 

 landmark. 



6. Otaka-e-C Sunosaki. The former should be a locality 



farther inland than Mochiyama.
