rushing waters could flow, being

nd wide--all bctoken the tooth Of
volcanic acid gases, perhaps accom-
panied by earthquake agitation.
IN this light they would say of our
inland bays, our creek bottoms, that
hey are in the main the bottoms of
!ncient cavcrns, which in the course
of rock-denudation have become UNI
capped.
They might cite TO their support oh
serVations to be met with in Lyell's
Principles Of Geology, page 100; topic,
Caycrnous Structures in Limestones.
Mr.. Strong has foreborne the express

The marked concretionaTy struc-

ing Of an CUTLER which has escaped
erosion.
Another disclosure Of anti-yulcan
ist piocliYity in Mr.. Strong was upon
his inspecting the remarkable Blue
Mounds springs. 10 lays down Ger
tain reasons for disalloWing that they
can be the representatives Of ancient
thermal springs. One is, that they
flow most ahundantly during and
after rainy spells. An important pre-
mise N the argument il here omitted,
about which we cim only iuterrogate:
Is this not the case with all mineral
spring waters, more or less? Does ii

atmosphere, IL is said, is then lighter
than before, and the pressure ON their
mouths less. So, too, on their heads, ac-
Cording to theory, il should be less.
