the Ifland of 5 1 . Miguel. .609 
Furnas, called the Sete Cidades^. This valley is fur- 
rounded with very abrupt mountains, about l'even or 
eight leagues round ; in the bottom is a deep lake of wa- 
ter, about three leagues in circuit, furnifhed with great 
number of water fowls. This water has no mineral 
quality; neither are there any hot fprings in the valley. 
All thefe mountains are compofed of a white crumbly 
pumice ftone, which is fo loofe, that, if a perfon thruft a 
ftick into the banks, whole waggon loads of it will tum- 
ble down. The inhabitants of the ifland relate a ftory., 
that he who firft difcovered it obferved an extraordinary 
high peak near the Weft-end ; but the fecond time he 
vifited it no fuch peak was to be feen, which he fup- 
pofed muft have certainly funk; but, however improbable 
this ftory may be, at fome period or another it muft have 
certainly been the cafe. 
If you fhould think the account of the mineral wafers 
of any fervice to the public, they are very welcome to it; 
and, fhould any perfon venture fo far for his health, a 
fmall ftock of the fuperfluities of life only need to be 
laid in, as the ifland yields every neceffary. The climate 
is very temperate : the thermometer fince I have been 
here has been no higher than 7 7 commonly from 70® 
to 75°.
