410 APPENDIX. 



N.W. end of Saint Mary's. Having daylight to proceed 

 by, close the land near the Paps of Bio Bio, and, keeping one 

 and a half mile from the shore, stand along the coast of Tal- 

 cahuana Peninsula. 



Should the Paps of the Bio Bio be clouded, the land about 

 them may still be known by the opening into Saint Vincent's 

 Bay, and by the land receding in the direction of the Bio Bio 

 river, as well as by high rocks lying off the points. The capes 

 of Saint Vincent's Bay on both sides are high and terminate 

 abruptly, and the south one has a large rock lying some dis- 

 tance off it. The northern cape is tabled, and has a small 

 tuft of trees near its edije. Table land extends from here to 

 Quebra Ollas. The Paps viewed from the westward appear 

 like an island ; the wide opening of the Bio Bio being seen 

 to the southward, and Saint Vincent's Bay to the northward. 

 The high rocks off the capes, at the foot of the Paps, are an 

 additional distinguishing mark; and when near enough the 

 rock of Quebra Ollas will be seen lying off the N.W. end of 

 the peninsula. About one third of the way between Quebra 

 Ollas and Saint Vincent's Bay, there is a large rock called the 

 Sugar Loaf. All this coast is bold, and may be sailed along 

 at a mile and half distance. Quebra Ollas rock lies the far- 

 thest off shore, and is distant exactly one mile and a quarter 

 from the cliff; it may be rounded at a quarter of a mile dis- 

 tance, if necessary, but nothing can go within it. 



Having passed Quebra Ollas, steer to the eastward, in or- 

 der to round Pajaros Ninos as closely as possible, and imme- 

 diately haul to the wind (supposing it from the southward), 

 for a long beat up to the anchorage. There are two passages 

 into Conception, but the eastern is the only one in use. On 

 the eastern shore of this channel there is no hidden danger, 

 until near Punta Para and Lirquen, when care must be taken 

 of the Para Reef, the Penco Shoal, and the flat of Roguan. 

 When near the two latter the southern head of Saint Vin- 

 cent's Bay comes open with Talcahuana Head, it will be time 

 to go round ; and it is not advisable at any time to open the 

 northern cape of Saint Vincent's Bay, distinguished by a tuft 

 of trees upon it, with Talcahuana Head. These two land-
