Rhine, and which suffitiently prove that 
the denominating of America anew world 
has been an opinion too hastily taken up. 
A copper mine was opened some years 
since further down the Mississippi, and 
to the great surprise of the labourers a 
large collection of the mining tools were 
found several fathoms below the sur- 
face of the earth, Another person, in 
digging for a well, discovered a furnace of 
brick work, five fathoms below the pre- 
sent surface, and in this furnace were 
found a quantity of coals and_ burnt 
wood. Not long since, at a spot on the 
Ohio, where the banks had been wasted 
by the undermining of the water, a stone 
dropped out, of the harder kind of black 
marble, about seven pounds in weight, 
having twelve equal surfaces, each sur- 
face being mathematically equilateral 
and equiangular five sided figures. Near 
the falls of the Mississippi, there is a salt 
spring, in the bed of the river, which has 
been inclosed with stone work of un- 
known antiquity, to keep out the fresh 
water. In times of freshes, however, the 
river overflows the stone-work, and mixes 
with the brine, so that it does not afford:

river is considerably fallen. In several 
places, circular fortifications have been 
discovered im the same country; these 
are constantly inclosed with deep ditches, 
and fenced with a breast-work. Some 
other facts will appear seon on this sub- 
ject in the Travels of Mr. Asie into 
those countries. 
EAST INDIES. 
M. Jouvvitxe, the only mineralogist 
in the island of Ceylon, has transmitted 
to Dr. De Carro, of Vienna, some inter- 
esting observations on its. mineralogy. 
From these it appears that no gems have 
been discovered in their matrices, all 
that he ever saw having been found in 
currents, and no others are in that mar- 
ket. It appears that the king of Candy 
is averse to permitting Europeans to ex- 
plore his mountains, and on the other 
hand, they are so thickly covered with 
the vegetation of ages, that no fissures 
are to be seen by which the mineralogist 
can be directed. The Candians take no 
further trouble to search fur stones or 
minerals than raking for them in the beds 
of currents after the rainy season, —
