peaks-, viz., the northern or Okunoin 2664 m. high, the southern or 

 Bessan 2376 m. high, and the central or Gozen, which is the highest 

 of all, 2687*5 m. 10 ) high. These peaks are for the most part of the 

 year covered with snow, to which fact the origin of the name Haku- 

 san or ' white mountains ' is probably due. From this part a range 

 branches off to the west, forming the boundary between Kaga and 

 Echizen, and a little further south, another branch runs in the 

 opposite direction, crossing the boundary between Hida and Mino. 

 For some distance the central range trends southward ; then turns 

 to the west and then again to the south. Here it blends with the chain 

 of Ibuki in Omi. The range in Kaga quickly decreases in height as 

 it extends westward, ending in a broad belt of plain running parallel 

 with the coast of that province. 



The Hakusan group, occupying the highest part in the whole 

 chain and soaring between the three provinces above named, gives 

 rise to numerous watercourses which feed the Tetorigawa in Kaga, 

 the Kuzuryfigawa in Echizen and the Shirakawa in Hida, all of 

 which empty themselves into the Japan Sea. 



The Tetorigawa has two sources. A stream that springs in 

 Okunoin called Ozôgawa flows northward and joins with the Haku- 

 sangawa coming from Bessan at Kinameri. The river then runs north - 

 ward through a narrow valley down to Tsuruki, a little below which 

 it trends to the west, and flowing through a wide alluvial flat finally 

 enters the sea at Yoshikawa, after a course of 20 ri (78 kilom.) 



The Kuzurijagawa is fed by three principal streams. One of 

 these, the Ishidoshirogawa, has its source in Bessan and flows south- 

 west from that mountain to Asahi, where it joins with the other two 

 coming from the boundary of Mino. The river then pursues a north-

 measurements may be considered more accurate than those published hitherto.
