The prickly pear "nopal" was the most common, and bore delicious, juicy and refreshing fruit.

Indeed, being out of water and short of "chuck," we were glad to accept Nature's offering, but at a dreadful cost, for in a little while our mouths and tongues were a mass of tiny, almost invisible spines, which the most careful manipulation of the fruit could not prevent.

But the most astonishing of these growths was the pitahaya (correct name saguarro), or gigantic columnar cactus, growing to a height of thirty to fifty feet, bearing the fruit on their crowns; a favourite fruit of the Pima Indians, though by what means they pluck it it would be interesting to know.

Besides an infinite variety of others of the cactus family, there were yuccas, agaves and larreas; the fouquiera and koberlinia, long and thorny leafless rods; artemisias and the algarrobbas or mesquite bean-trees, another principal food of the Indians and valuable for cattle and horses.

The yucca when in full bloom, its gigantic panicles bearing a profusion of large white bells, is one of Nature's most enchanting sights.
