HOT SPRINGS in ICELAND. 149 
Or thefe jets we counted twenty in an hour and an half, 
during which the waters had filled the pipe and in part the 
bafon. It then feemed oftentimes agitated, and boiled with 
great violence. The jets were more beautiful, and continued 
songer, as the quantity of water ia the bafon increafed. The 
refiftance being greater, their force was in fome degree broken, 
and their form, more divided, produced a greater difplay of 
foam and vapour. 
Wuite the pipe was filling, we threw into it feveral {tones: 
of confiderable weight, which, whenever the water burft forth 
with any violence, were projected much higher than itfelf. 
Thefe ftones in falling were met by other columns of water, 
and amidft thefe they rofe and fell repeatedly. They were ea- 
fily diftinguifhed in the white foam, and contributed much to 
the novelty and beauty of this extraordinary phenomenon. 
WueEn the bafon was nearly full, thefe occafional eruptions: 
were generally announced by fhocks of the ground, fimilar to. 
thofe preceding the great eruptions. Immediately after the: 
fhocks, the whole body of water in the bafon heaved. exceed- 
ingly 5 a violent ebullition then took place, and large waves. 
f{pread themfelves in circles from. the centre, through which: the: 
column forced its way. 
WueEw the water had been quiet in the bafon for fome time,, 
the thermometer placed in it ftood at 180° only, but imme- 
diately after an eruption it rofe to 200°. We boiled a piece of. 
falmon in it, which was exceedingly eg tafted. Our cookery’ 
at Rykum had not been quite fo fuccefsful. 
THE water thrown out from the Geyzer is joined at the: 
bottom of the mound by that which flows from the {pring 
called the roaring Geyzer, formerly defcribed. The ftream pro- 
duced by their united waters flows three or four hundred paces 
before it falls into the river, where its temperature is reduced. 
to 72°. Even at this place it depofited much of the fubftances, 
it.contained ; but during the whole of its courfe, the plants:
