APPENDIX. 



Farther inshore are ranges of mountains alway s covered with snow, 

 whose height is from two to four thousand feet, and in a few instances 

 about six or seven thousand. 



With dayUght and clear weather a vessel may close the shore with- 

 out risk, because the water is invariably deep, and no rock is found, 

 which is not so marked by sea- weed (or kelp as it is generally called), 

 that by a good look-out at the mast-head, its situation is as clearly 

 seen as if it were buoyed. By avoiding kelp you are sure of having 

 sufficient water for the largest ships on any part of this coast. At 

 the same time, it must be remembered that kelp grows in some 

 places from a depth of thirty fathoms, and that on many parts of this 

 coast you may pass through thick beds of sea-weed without having 

 less than six fathoms water ; still it is always a sign of danger, and 

 until the spot where it grows has been carefully sounded, it is not 

 safe to pass over it with a ship. As an instance ; — after sounding a 

 large bed of this weed in one of the Beagle's boats, and thinking it 

 might be passed safely, a rock was found, not more than four feet in 

 diameter, having only one fathom w'ater over it. 



Viewing the coast at a distance, it appears high, rugged, covered 

 with snow, and continuous, as if there were no islands. When near 

 you see many inlets which intersect the land in every direction, and 

 open into large gulfs or sounds, behind the seaward islands : and 

 you then lose sight of the higher land, which is covered with snow 

 throughout the year, and find the heights close to the sea thickly 

 wooded towards the east, though barren on their western sides, owing 

 to the prevailing winds. These heights are seldom covered with 

 snow, because the sea winds and the rain melt it soon after it falls. 



Opposite to the eastern valleys, wl\ere the land is covered with 

 wood, and water is seen falling down the ravines, good anchorage is 

 generally found. But these valleys are exposed to tremendous squalls 

 which come from the heights. The best of all anchorages on this 

 coast is where you find good ground on the western side of high land, 

 and are protected from the sea by low islands. It never blows near 

 so hard against high land as from it ; but the sea on the weather side 

 is of course very formidable, unless stopped, as I mentioned, by islets. 



Where the land is chiefly composed of sandstone or slate, anchor- 

 ages abound ; where of granite, it is difficult to strike soundings. 



The difference between the granite and slate or sandstone hills, 

 can be distinguished by the former being very barren and rugged,
