Ma-s.vn-i-h.. ^Ve ilnally readied the newly opened port of Masan-pJio 



(IM. 1 1. .////. o). This port was formerly called TIap-pho^\ and 

 is the place where the combined forces under the ^longol 

 (ieneral Hung "'•' and the Korean (leneral Kbe ^-^ made their prepara- 

 tions, and set sail for the ever memoral)le invasion of llakata in 

 northern Kynsliü, but were completely annihilated by a destruc- 

 tive gale in the Tsu-shi-ma Straits in 1281. We can still tind a

 ers. There is still another relic of historic importance. I refer 

 to the citadel of the Daimyo Shimadzu ^' ? (see fig. ?>) during the 

 invasion of ITideyoshi from 1502 to 1598. The citadel Mes behind 

 the native village of Ma-mn-phn, and is itself a low isolated hill 

 of granite, capped as usual In- the green eruptive. It is a detach-

 the formation of the hai'bor of Ma-san-pho is surely due. 



The canal of Ma-san-pho and the gulf of Cliin-häi are twin 

 arms of the sea sepai'ated by a small tongue of land and 

 protected in front by (he large island of /\'ö-/^öi". They have a, 

 common entrance towards the south-east between this and the 

 island of Ka-döJx''\ I'otli harbors are well-protected by surround- 

 ing mountains, and are deep enough to aflbrd good anchorage. 

 Tiiey are destined to Ix'come the important harbors of the south- 

 eastern extremity of the Korean ])cninsula.
