The saguaro, or giant cactus, is one of nature's rare and curious
productions. It is a large, round, fluted column that is from
one to two feet thick and sometimes sixty feet high. The trunk
is nearly of an even thickness from top to bottom but, if there
is any difference, it is a trifle thicker in the middle. It
usually stands alone as a single perpendicular column, but is
also found bunched in groups. If it has any branches they are
apt to start at right angles from about the middle of the tree
and curve upward, paralleling the trunk, which form gives it the
appearance of a mammoth candelabrum.
The single saguaro pillar bears a striking resemblance to a
Corinthian column. As everything in art is an attempt to imitate
something in nature, is it possible that Grecian architecture
borrowed its notable pattern from the Gila valley?
Southern Arizona is the natural home and exclusive habitat of
this most singular and interesting plant and is, perhaps, the
only thing growing anywhere that could have suggested the design.
Wherever it grows, it is a conspicuous object on the landscape
and has been appropriately named "The Sentinel of the Desert."
Its mammoth body is supported by a skeleton of wooden ribs, which
are held in position by a mesh of tough fibers that is filled
with a green pulp. Rows of thorns extend its entire length which
are resinous and, if ignited, burn with a bright flame. They are
sometimes set on fire and have been used by the Apaches for
making signals. The cactus tree, like the eastern forest tree,
is often found bored full of round, holes that are made by the
Gila woodpecker. When the tree dies its pulp dries up and blows
away and there remains standing only a spectral figure composed
of white slats and fiber that looks ghostly in the distance.
Its fruit is delicious and has the flavor of the fig and
strawberry combined. It is dislodged by the greedy birds which
feed on it and by arrows shot from bows in the hands of the
Indians. The natives esteem the fruit as a great delicacy, and
use it both fresh and dried and in the form of a treacle or
preserve.
The ocotillo, or mountain cactus, is a handsome shrub that grows
in rocky soil upon the foothills and consists of a cluster of
nearly straight poles of brittle wood covered with thorns and
leaves. It blossoms during the early summer and each branch
bears on its crest a bunch of bright crimson flowers.
If set in a row the plant makes an ornamental hedge and effective
fence for turning stock. The seemingly dry sticks are thrust
into yet drier ground where they take root and grow without
water.
