served the same circumstance, so that in all pro¬ 
bability their subterraneous streams are quite 
independent of each other*. We were informed 
by the people living in the neighbourhood, that 
in the spring of last year (1808), a violent shock 
of an earthquake was felt, which made an aper¬ 
ture for another hot spring, and caused the whole 
of them to cease flowing for fifteen days. The 
ground, at that time, appeared to be lifted up some 
feet; a house was thrown down, and all the cattle, 
which were at pasture, ran home to the dwel¬ 
lings of their masters, and showed symptoms of 
the greatest terror. Earthquakes in this quarter 
* Horrebow, indeed, seems to lead to a contrary conclusion, 
from the following observations: “ In the parish of Huusevig , 
“ at a farm called Reykum, there are three springs which 
“ lie about thirty fathoms from each other. The water boils 
(e up in them in the following manner: when the spring or 
“ well at one end has thrown up its water, then the middle 
(( one begins, which subsiding, that' at the other end rises, 
ft and after it, the first begins again, and so on in the same 
se order by a continued succession, each boiling up three 
“ times in about a quarter of an hour.” Page 21 .—Povelsen 
and Olafsen, also, mention a remarkable circumstance, 
which proves a communication between the two springs, 
called Akraver, in the canton of Olves, situated at the dis¬ 
tance of an hundred toises from each other. On throwing 
in the lead, for the purpose of sounding the depth of one 
of these wells, they found the water immediately diminished 
a foot and a half in depth, whilst at the same time it flowed 
over from the other well.
