The telescope in this tower is not the usual type
of single-barrel machine. It is constructed exactly
like an opera glass, and the layman experience no
difficulty in seeing through it, as it needs no more
adjustment than any ordinary opera glass and the
field of vision is ten to twenty times greater than
through the ordinary single barrel machine.
The north rim of the Canyon, thirteen miles away,
with its forest of pines, appears only a half mile
away through the telescope.
This machine has been installed for the benefit
of all visitors to the Canyon and no charge is made
to anyone.
