G40 DU. JOHN LOWE ON WAYSIDE BOTANY IN NOUWAT. 
in all these cases is found more or less throughout the year, as in 
the root of the Fl(rrenHne irix ; but I think it is strongest in the 
autumn, and especially after frost, which developes strong perfumes 
in the leaves of several of our forest trees, such as the Plane-tree, 
which gives out a powerful scent, and the Ash, in which I have 
several times observed a very strong odour like that of Stephanotis. 
In these the scent is only developed after frost. 
On the mountains above Jerkind, Juniper and Dwarf Birch 
{Betula vana) abound. Many plants of the latter are apparently 
of great age, spreading along the ground for four or five feet. These 
serve as a great protection to various species of Cladonia, which 
e.xist here in singularly beautiful forms. Where the Birch and 
Juniper are absent, large patches of mountain are stripped of 
Reindeer Moss by the wind. 
The highly-elevated snow-line, and the absence of glaciers on the 
Dovrefjeld, have been the frequent subject of comment by writers 
on Norway. Thus, Lieut. Biddulifii " says : “ It is worthy of remark 
that the Folgefond, though of less elevation than the Hardanger, from 
which it is only separated by the Fjord, holds more ice and snow ; 
the latter exhibiting no glaciers, even round the towering peak of 
the Harteigen. But it is still more remarkable that the Dovre- 
fjeld, one hundred and fifty miles farther north, which rears its 
highest point, Sneehatten, to the height of 7513 feet (upwards of 
2000 feet higher than the highest part of the Folgefond), and is 
further inland, and consequently more removed from the mollifying 
influences of the Atlantic breezes, has not a single glacier and no 
extended back of snow.” Professor Edward Forbes t noticed that 
the snow level on the mountains near Vossevangen was extraordi- 
narily low compared with that of the Fillefjeld and Dovrefjeld.” 
The reason of this is not far to seek, and may be found, I think, in 
the fact that the large amount of vapour brought along the coast 
by the Gulf Stream is precipitated by the cold of the Folgefond 
and the mountains near the coast, falling as rain in the Bergen 
district, and as snow on the Folgefond and mountains. The rain- 
clouds are thus almost deprived of moisture, the rainfall at Bergen 
being annually 72'25 inches, and at Floro 75*27 ; while on the 
Dovrefjeld it is only 14*39 inches, and thus the snowfall in this
