breast of a skeleton, in a carefully constructed stone coffin, in a
mound near Nashville, Tennessee.

Lenormant remarks ("Anc. Civil.," vol. ii., p. 158) that the bronze
implements found in Egypt, near Memphis, had been buried for six
thousand years; and that at that time, as the Egyptians had a horror of
the sea, some commercial nation must have brought the tin, of which the
bronze was in part composed, from India, the Caucasus, or Spain, the
nearest points to Egypt in which tin is found.

Heer has shown that the civilized plants of the lake dwellings are not
of Asiatic, but of African, and, to a great extent, of Egyptian origin.
Their stone axes are made largely of jade or nephrite, "a mineral which,
strange to say, geologists have not found in place on the continent of
Europe." (Foster's "Prehistoric Races," p. 44.)

Compare this picture of a copper axe from a mound near Laporte, Indiana,
with this representation of a copper axe of the Bronze Age, found near
Waterford, Ireland. Professor Foster pronounces them almost identical.

Compare this specimen of pottery from the lake dwellings of Switzerland
with the following specimen from San Jose, Mexico. Professor Foster
calls attention to the striking resemblance in the designs of these two
widely separated works of art, one belonging to the Bronze Age of
Europe, the other to the Copper Age of America.
