Glade confusion

I must know what is synthetic:
what is synthetic I must know.
Natural is the brick and stone.
Natural is the turnip row.

I must know what’s manufactured:
manufacture I must come to learn.
Natural is the rope bridge swinging
and the extinction of the fern.

I must find out what machines are:
machines—I’ve got acquaintances to make.
Natural is the iPad touch screen,
the intuitive control, the hyperlink.

I must meet with the machinery
and the factory, and everything man-made.
Natural is the way that electricity
permits you to enjoy the smell of Glade.
