them living within a quarter Of a nail.

The subterranean lake Of the Dru..n
is the largest known. being about zee
yards long and 81 yards wide, vita
maximum depth of 30 feet. As the
water seems to be a mixture OF sea
water with three times its volume Of
fresh water, there is probably esaas
communication with the MediteHs-
mean. The roof over the lake is stuases
with stalactites. and stalagmites sss7s
in it as islands.

without interruption from Naples 10
Baia, and these are being accurately
charted. The work done indicates hst
the level of the Mediterranean hs.

piers and villas were constructed. the
survey will have great practical value .
as well scientific interest, for the
submerged foundations endanger asvi-
cation and many vessels strike on
them.
