savages inhabiting the interior of Borneo.

As I have said, this more or less rhythmic clanking of stones
together, the striking of wooden paddles against the side of
a canoe, or the clashing of stone spearheads against wooden
shields, could not constitute the first musical instrument. But
when some savage first struck a hollow tree and found that
it gave forth a sound peculiar to itself, when he found a
hollow log and filled up the open ends, first with wood,
and then--possibly getting the idea from his hide-covered
shield--stretched skins across the two open ends, then he had
completed the first musical instrument known to man, namely,
the drum. And such as it was then, so is it now, with but
few modifications.

Up to this point it is reasonable to assume that primeval man
looked upon the world purely subjectively. He considered himself
merely a unit in the world, and felt on a plane with the other
creatures inhabiting it. But from the moment he had invented the
first musical instrument, the drum, he had created something
outside of nature, a voice that to himself and to all other
living creatures was intangible, an idol that spoke when it
was touched, something that he could call into life, something
that shared the supernatural in common with the elements. A
God had come to live with man, and thus was unfolded the
first leaf in that noble tree of life which we call religion.
Man now began to feel himself something apart from the world,
and to look at it objectively instead of subjectively.

To treat primitive mankind as a type, to put it under one head,
