DB. JOHN LOWK ON WAYSIDE BOTANY IN NORWAY.

with axes into the woods, and cut down branches, of which they 
made huge fires at stated intervals, putting on during the night 
a continual supply of green fuel, so as to create as much smoke as 
possible, the object being to fill the valley full of smoke, and thus 
to check radiation. Mr. Dombaas believes that they could always 
in this way make a difference of several degrees, and thus save their 
crops. On the present occasion the night came over thick and 
cloudy, and the freezing point was not reached, 1° Cels, only being 
registered. On the mountain opposite Dombaas were a number of 
good plants, such as Gentiana nimlix and G. t('nella, in great 
profusion; Comllorhiza inuafa also abundant; llaiteuoria riridifi, 
Gi/nniaifenia (‘ouopxm, J‘i/i oIa rotumli/nUa, /'. uuijfora, Saxi/iwja 
tridarf;/litex, Li/copoilinm a/pinuiii, etc. At .lerkind, Carex iw-urra 
was found covering the roadside for some miles, as afterwards at 
Dalen. In llritain there is, 1 believe, only one locality for this 
plant, viz., on the shore of the Frith of Forth at Long Xiddry, 
where I found it growing very many years ago. The late Professor 
Palfour told me that he had been unable to find it in this locality. 
There was a considerable patch of it in 18.‘37, but it may have since 
disappeared, as it grew near to the shore of the Frith of Forth. 
I also noticed Luznia arcuafa, Lijrhnis nWaria, L. a/j>ina, J^edte- 
idarix (e>hri, Axtrapahis ornhndex, A. a/piiia, Vahlbenje/la ajfefala, 
Itanunru/ux tjIariaJix, ('ardaiiiine aniara, Venmira a/jnua, Piiii/id- 
cilia I'lilifaris, PItIcum alphnim, Primula xcnfica, Anemone rernalix, 
etc. iSaxi/raija cerniia, which I found on the Dovrefjeld on my 
former visit, attains a much liner form than it does in Scotland, 
where it seldom llowers, being propagated only by bulbils, while 
here it produces fine llowers freely, and probably ripens its seeds. 
On digging up some roots of Primula xenfica, 1 found that they 
emitted a delicious odour of Violets, three or four roots giving off 
as much perfume as a large bundle of those flowers. The roots 
of Primula xtrirfa, which I found subsec^uently, were equally scented, 
and P. /arinoxa has the same peculiarity. In a large number of 
other species which I have since examined this odour could not be 
detected. Lindley mentions the roots of P. verix as smelling of 
aniseed, and s<ays that it was formerly employed as a nervine tonic, 
and also as a diuretic.* I should rather describe this as the odour 
of “ laudanum,” which is common to many other species. The scent
