136 An ACCOUNT of 
Mr Barwne, by a meafurement of the depth, the breadth and 
the velocity of the ftream flowing from the little Geyzer, found 
the quantity of water thrown up every minute by it to be 
590.64 wine gallons, or 78.96 cubic feet. Mr Wricut and 
myfelf followed the ftream, to obferve how far any matter con- 
tinued to be depofited by the water. We found fome little ftill 
depofited where it joined the river, a quarter of a mile at leaft 
from its fource. At that place, it retained the heat of 83 de- 
grees by FAHRENHEIT’s thermometer. 
Tue vegetation on the banks of the ftream, and in the plea- 
fant meadows through which it flows, is exceedingly luxuriant. 
The farmer and his people were at this time employed in cutting 
the hay in them, which, though not high, was thick, and re- 
markably fweet. The plants which Mr Wricut found in the 
greateft perfection, were the fedum acre*, the veronica beca- 
bunga +, the polygonum viviparum {, and the comarum pa- 
luftre ||. 
A LITTLE above, where the current from the little Geyzer 
falls into the river, part of the lava, which has defcended 
from the upper into the lower plain, has affumed clofe to its 
banks, for the fpace of fome yards, a regular columnar fhape. 
The pillars are fhort, and have five or fix fides. I cannot be 
very exact in my account of them, as they were on the oppo- 
fite fide of the river. I fhould fuppofe they were nearly a foot 
and an half in diameter.. Some were horizontal, and others ver- 
tical. We obferved the fame appearance in many of the traéts 
of lava we traverfed on our journey, and, in one or two in- 
ftances, in thofe which had flowed from the fides of Mount 
Hecla, though the pillars there were lefs perfectly defined. 
So many ftreams of hot water fall into the river, that it re- 
ceives from thence a very perceptible degree of heat. The
