The force of the vapours that
llirow up this water is exceffive ; it
not
not only prevents the itoiies that are
thrown into the opening from finking,
but even throws them up to a
very great height, together with the
water. I muff not forget to mention
a very curious circurnftance : when
the bafon was full o f water, we placed
ourfelves before the fun in fuch a manner,
that we could fee our iliadows
in the water; every one obferved round
the fliadow o f his own head (though
not round the heads o f tlie others) a
circle o f almoft the fame colours
that compofe the rainbow, and round
this another bright circle : this moft
probably proceeded from the vapours
exhaling from the water, I remember
to have feen fomething fimilar tp
it when travelling in the fummer,
particularly in the meadows, and it is
fooneft obferved when riding 011
horfeback, or in a carriage, when
you have your fliadow on one fide.
Nop far from this place another
fpring, at the foot of the neighbouring
ridge of rocks, fpouted water to the
height o f one or two yards each time.
