306 Lieut.-Col. Hagclstam on the Regions of 



From 64° to 63°. — Gooseberries. The snow region to the west 

 of the mountain range (Fjallrygg) is 4800 feet. Maple. Apple- 

 trees. Cherry and plum trees in the valleys near the coast. 



From 63° to 62°.— Pear-trees. Hazle. The oak found 

 wild only along the coast, and most between Holmestrand and 

 Mandal. It is planted as high as Drontheim, although very 

 thinly. The snow region is 5300 feet above the Dovrefield. 

 The walnut is planted, though it does not produce any fruit. 

 Elm and linden. 



From 62** to 61°. — The snow region upon the Langfield is 

 5410 feet. Asparagus. Between the Latitude of 58|° and 62°, 

 the surface of the principal mountain chain is nearly altogether 

 flat. 



From 61° to 60°.— At 61° the snow region upon the Fillefield 

 is 5600. The perpetual glacier upon the Sneebraen and the 

 Folgefonden has now increased downwards to J 000 feet above 

 the level of the sea in several places. 



From 60° to 59°. — The snow region upon the mountain chain 

 is 5800 feet ; upon the Folgefonden it is 5000 feet. A water- 

 fall of 946 feet perpendicular has been lately discovered, by 

 Professor Esmark, in a valley in Bradsbergs Amt ; it is called 

 Raukenfossen. Beech wood is found only in the country be- 

 tween Laurvig and Tonsberg. 



From 59° to 58°. — Wild rein- deer upon the chain of moun- 

 tains. 'The constant temperature of the earth along the Nor- 

 way coast is, at Vadsoe, in East Finmark, 34° T ; at Alten- 

 gaard, in Finmark, 35° /^ ; about Drontheim, 40° ; at Lyster, 

 in the northern part of Bergen's Amt, 42° 8^ ; at Laurvig, 

 about 45° 5' ; at Christiana, about 44° 6' ; (at Paris it is 53° 3'). 



The above observations were made before 1810. In the 

 centre of the Scandinavian peninsula, and on each side of the 

 alpine ridge, in round numbers 500 perpendicular feet above 

 the level of the ocean, cause as great a change and decrease in 

 the climate and vegetation, as from 120 to 150 miles horizontal 

 distance towards the north ; 1000 feet in perpendicular height, 

 equal from 26 to 325 miles ; and 2000 perpendicular feet, about 

 585 miles. To the northward of Drontheim, up to Lat. 67° N. 

 500 feet in perpendicular height are equal only to from 120 to 

 130 miles, and 1000 perpendicular feet from 225 to 260 miles,
