repair of a dam would be necessary to make it again
effective.

MONTEZUMA CASTLE NATIONAL MONUMENT

Small though it is, Montezuma Castle is justly one of the most
celebrated prehistoric ruins in America. Its charming proportions, and
particularly its commanding position in the face of a lofty precipice,
make it a spectacle never to be forgotten. It is fifty-four miles from
Prescott, Arizona.

This structure was a communal house which originally contained
twenty-five rooms. The protection of the dry climate and of the shallow
cave in which it stands has well preserved it these many centuries. Most
of the rooms are in good condition. The timbers, which plainly show the
hacking of the dull primeval stone axes, are among its most interesting
exhibits. The building is crescent-shaped, sixty feet in width and about
fifty feet high. It is five stories high, but the fifth story is
invisible from the front because of the high stone wall of the facade.
The cliff forms the back wall of the structure.

Montezuma's Castle is extremely old. Its material is soft calcareous
stone, and nothing but its sheltered position could have preserved it.
There are many ruined dwellings in the neighborhood.

TONTO NATIONAL MONUMENT

Four miles east of the Roosevelt Dam and eighty miles east of Phoenix,
Arizona, are two small groups of cliff-dwellings which together form the
Tonto National Monument. The southern group occupies a cliff cavern a
hundred and twenty-five feet across. The masonry is above the average.
The ceilings of the lower rooms are constructed of logs laid lengthwise,
upon which a layer of fibre serves as the foundation for the four-inch
adobe floor of the chamber overhead.

There are hundreds of cliff-dwellings which exceed this in charm and
interest, but its nearness to an attraction like the Roosevelt Dam and
glimpses of it which the traveller catches as he speeds over the Apache
Trail make it invaluable as a tourist exhibit. Thousands who are unable
to undertake the long and often arduous journeys by trail to the greater
ruins, can here get definite ideas and a hint of the real flavor of
prehistoric civilization in America.

WALNUT CANYON NATIONAL MONUMENT

Thirty cliff-dwellings cling to the sides of picturesque Walnut Canyon,
eight miles from Flagstaff, Arizona. They are excellently preserved. The
largest contains eight rooms. The canyon possesses unusual beauty
because of the thickets of locust which fringe
