Everywhere near the shady creeks I saw the evening primrose, brilliantly yellow, while the intense, carmine-red flowers of the lobelia peeped out from under the shrubs.

But of all the flowers on the banks of the streams, the most remarkable was the exquisitely beautiful _Datura meteloides_, with its gorgeous white crown, six inches long and four inches wide.

We saw one cluster of this creeper fully fifty feet in circumference.

It is well known among the Navajo Indians that the root of this plant, when eaten, acts as a powerful stimulant; but the better class among the tribe look upon it with disfavour, as its use often leads to madness and death.

The effect of the poison is cumulative, and the Indians under its influence, like the Malays, run amuck and try to kill everybody they meet.
There is also found a species of cactus, with a root which looks like an enormous carrot.
