On the Physical Geography of Norvjay. 303 



1. The Folgefond, on the south-west of the Har danger 

 country, is the most important of that region. An outlying 

 hill (latitude 59 0, 9) above Rosendal, called Melderskin, is 

 covered with perpetual snow (according to Hertzberg), though 

 its height is only 4558 Rhenish, or about 4700 English feet. 

 We may suppose the snow line to be at least 200 feet lower, 

 as the summit is isolated, say 4500. 



2. Lat. 60°*1. On the western or seaward side of the 

 Folgefond, nearMoranger-fiord, by my observation, the snow 

 begins at 3800 or 3900 English feet.* 



3. Lat. 60°-l. The landward or eastward side of the Folge- 

 fond ceases to be covered with snow according to the same 

 authorities, at 1697 metres, or about 5240 English feet. 



4. This last elevation has been also determined by Nau- 

 mann {Travels, i. 130), but with a very different result. The 

 mean of two observations of 4100 and 3950 Rhenish feet cor- 

 responds to 4150 English feet. 



All the preceding determinations are subject to some 

 doubt. In the first the snow line is not directly measured 

 at all, only the summit of the hill. In the second, the baro- 

 meter was acting imperfectly. The third is unquestionably 

 much too high from a comparison with the determined height 

 of various parts of the " fond" (see Gcea Norvegica, p. 159), 

 certainly many hundred feet above the snow line. The 

 fourth, on the other hand, is as certainly somewhat too low, 

 the observation having been taken (Naumann, i. 109) at an 

 outfall or depression of the glacier. It seems to me very 

 probable that a mean of the whole will be tolerably correct, 

 which gives nearly 4400 English feet. 



5. Lat. 60°-2. Hartougen, in the Hardanger-field (Smith), 

 5000 Rh. ft. = 5150 Eng.— Lat, 61°. The interior range of 

 the Fille-field (Von Buch), 1694 metres, about 5560 English 

 feet. Mean 5400 Eng. feet. 



6. Lat. 61 0, 5. Outlying portion of Justedals Brseen to- 

 wards the sea, between Jolster and Indvigs-fiord, according 

 to Naumann, about 4000 Rhenish, or 4120 English feet. 



* This observation though subject to some doubt, is well confirmed by the 

 limit of the birch, as ascertained by Professor Christian Smith of Norway.
