GENERAL REMARKS 
the flowers are even produced during the Enow. The leaves of 
the tujjilago , however, never come out till about a fortnight after 
the fnow is gone. 
The Andromeda crermea adorns the bogs of Lapland. I found 
fome entirely white, and gathered feveral fpecimens of them. 
The willows are numerous in Lapland, but it is rather difficult 
to know them, as in many the time of the flower and that of the 
leaves is different. They are a ufeful production for the economy

and by their long and winding roots, they keep the banks of 
brooks and rivers together, which would otherwife crumble to 
pieces. The Laplanders make cords of the roots of the willow, 
which they ufe in their fiflieries. 
The quicknefs of the vegetation in Lapland is a thing of which 
we have no conception in other parts of Europe. The whole is 
accomplifhed in the fpace of tw T o months; and to give the reader 
a more accurate idea of it, I will mention as an example, that a 
tobacco plant at Enontekis generally increafes more than an inch 
in circumference during the interval of tw T enty-four hours. 
I remarked in my travels what trees extended farthefl to the 
north, and from this 1 abftraded a kind of rule for the latitude 
in which I found myfelf. For inftance, from Tornea as far as 
Ketkemando, you meet with firs, pines, and birches, promifeu- 
oufly: but beyond Ketkemando the firs difappear, and you only
