ties of glass bottles drifting off the coast, which only 
the inhabitants of the Lofoden Isles, and of Finmarken 
use in their cod fisheries as floats for the nets. 
Thus the northern parts of Norway are not only 
habitable, but are considered by many as agreeable 
places of residence. 
But there is another cause, which, in connection with 
the above, exercises a great influence on the vegetation 
of the whole country—the more appreciable the higher 
the latitude,—and that is the long days, or, in other 
words, the continued light. Under lat. 70° the sun 
never sinks below the horizon from May 24th til 
July 19th. At Throndhjem, lat. 63° 25' 45", it rises 
at 1°50 a.m. on June Ist, and sets at 10°13 P.m.; 
and at Christiania, lat. 59° 54' 43”, it rises on this date 
at 2°40 am., and sets at 9°23 p.m. Consequently, 
during this period, the earth does not become so cooled 
during the short nights as in more southern latitudes, 
and therefore vegetation continues without interruption. 
Thus, in Norway, a continuous degree of warmth 
produces the same effect that a higher temperature 
during the day, and colder nights do in countries 
further to the south. 
_ It might not unnaturally be supposed that, owing to 
the greater distance from the equator, a longer time 
would be required for the development of a plant 
the further it is found to the north. Such, however, is
