APPENDIX, 259 



uncertain; but, generally speaking, three feet may be considered 

 about the extent to which it ranges. The sea breeze sets in so 

 strongly occasionally, that it is difficult for boats to pull ao-ainst it ; 

 this is particularly the case under the high land, whence it comes 

 in sudden gusts and squalls. 



In coming from seaward, the best way to make this port is to 

 stand in on a parallel of 10° 06', and when within a few leagues of 

 the coast, a sharp -peaked hill, with a large white mark on it, will be 

 seen standing alone a little north of the port : the break in the 

 hills through which the river runs, is high and clifiy on each side. 

 The land is also much lower to the northward of Legarto Head; 

 and there is a large white islet at the north end of Guarmey Bay. 



N. 34° W., seven miles and a half from the white islet at the 

 north extreme of Guarmey Bay, is Point Culebras, a level project- 

 ing point, similar in appearance to Legarto Head, as seen from the 

 northward ; the coast between is a mass of broken cliffs and innu- 

 merable detached rocks, with moderately high land near the coast. 



On the north side of Point Culebras, there is anchorage off the 

 valley of that name. From this point the coast is rocky, with small 

 sandy bays, and some rocks lying off it about three quarters of a 

 mile ; there is also a white clifiy islet, five miles to the northward of 

 Culebras ; whence the coast takes a bend inwards, forming^a bay, 

 and then runs out towards the Colina Redonda ; a point with two 

 hummocks on it, and as seen from the southward, appearing Hke an 

 island. On the north side of this point is the Caleta (only fit for 

 boats) ; and immediately over it, the Cerro Mongon. 



The Cerro Mongon is the highest and most conspicuous object on 

 this part of the coast ; when seen from the westward it has the ap- 

 pearance of being round, with rather a sharp summit ; but from the 

 southward, it shows as a long hUl with a peak at each end. It is 

 said there is a lake of fresh water on its summit, and that its valleys 

 abound with deer ; but the truth of this cannot be vouched for, as 

 our examination did not extend so far. 



From Mongon there is a range of hills running parallel to the 

 coast (which is high and rocky, with some white islets lying off it) 

 as far as Casma, where they terminate in a steep rocky bluff, that 

 forms the southern head of the port of that name. 



The Bay of Casma is a snug anchorage, something in the form of 

 a horse-shoe ; at its entrance it is a mile and three quarters in a
