SAILING DIRECTIONS AND NAUTICAL REMARKS. 385 



To make the foregoing directions more easily comprehended, they have heen rendered as con- 

 cise as possible ; but to furnish further information to navigators bound to or passing the port, 

 the additional remarks are appended. 



The harbor of Simoda is near the southeastern extremity of the peninsula of Idzu, which 

 terminates at the cape of that name. To the northward of the harbor a high ridge intersects 

 the peninsula ; and south of this, all the way to the cape, it is broken by innumerable peaks of 

 less elevation. 



The harbor bears S.W, by W. from Cape Sagami, at the entrance of Yedo bay, distant 

 about forty-five miles. 



Eock island is about 120 feet high and a third of a mile in length, with precipitous shores 

 and uneven outlines. It has a thick matting of grass, weeds, moss, &c, on the top. 



From the summit of this island overfalls were seen, bearing N. ^ W., distant a mile or a 

 mile and a half. These may have been caused by a rock or reef. An attempt was made to 

 find it, but the strong current and fresh wind prevented a satisfactory examination. The 

 Japanese fishermen, however, deny the existence of any such danger. 



N. by W. from Eock island, distant two miles, are the Ukona rocks. These are two rocks 

 though they generally appear as one. The largest is about 70 feet high. Between these and 

 rock island the current was found setting E. N. easterly, fully four miles an hour. 



Centre island bears from rock island N. \ E. , distant 5\ miles, and from Ukona rocks, N. by 

 E. \ E., distant 3£ miles. 



Buisako islet lies N.N.E. from Centre island. It is about 40 feet high, and covered with 

 trees and shrubs. 



Should the buoy on Southampton rock be removed, the east end of Centre island on with the 

 west end of Buisako, will clear the rock to the westward. 



Off the village of Susaki, and distant one-third of a mile from the shore, is a ledge of rocks 

 upon which the surf is always breaking ; give them a berth of two cables in passing. 



Cape Idzu, latitude, 34° 36' 00" N., longitude, 138° 50' 35" E. Kock island, latitude, 

 34° 34' 20" N., longitude, 138° 51' 10" E. 



S. W. from Koza-Sima, distant about 20 miles, and south a little westerly from Cape Idzu, 

 distant about 40 miles, there are two patches of dangerous rocks, 15 or 20 feet high, which 

 have been named Eedfield rocks. They are in latitude 33° 56' 13" N., longitude 138° 48' 31" 

 E., and latitude 33° 51' 31" N., longitude 138° 49' 13" E. 



These positions may not be strictly correct, but it is believed they are not much out of the 

 way.

A lookout place shall be established at some convenient point, from which vessels appearing 

 in the offing can be seen and reported ; and when one is discovered, making apparently for the 

 harbor, a boat shall be sent to her with a pilot.
