implements of the stone age, but are of sufficient variety to
indicate a succession of races that were both primitive and
cultured and as widely separated in time as in knowledge.

The cliff dwellings were not only the abodes of their original
builders, but were occupied and deserted successively by the
chipped stone implement maker, the polisher of hard stone, the
basket maker and the weaver.

Among the relics that have been found in the ruins are some very
fine specimens of pottery which are as symmetrical and well
finished as if they had been turned on a potter's wheel, and
covered with an opaque enamel of stanniferous glaze composed of
lead and tin that originated with the Phoenicians, and is as old
as history. Can it be possible that the cliff dwellers are a
lost fragment of Egyptian civilization?

The cliff ruins in Arizona are not only found in the canons of
the Colorado river, but also in many other places. The finest of
them are Montezuma's Castle on Beaver creek, and the Casa Blanca
in Canon de Chelly. Numerous other ruins are found on the Rio
Verde, Gila river, Walnut Canon and elsewhere.

The largest and finest group of cliff dwellings are those on the
Mesa Verde in Colorado. They are fully described in the great
work[5] of Nordenskiold, who spent much time among them. The
different houses are named after some peculiarity of appearance
or construction, like the Cliff Palace, which contains more than
one hundred rooms, Long House, Balcony House, Spruce Tree House,
etc.
