"THE WELL OF THE DESERT"
From photograph by C. C. Pierce & Co.

It was a most memorable trip. At no other season of the year does the desert present so gay an appearance as in May and early June. Blossoms, white, pink, yellow, purple, and scarlet, are to be seen on all sides, till one loses the idea that he is in the desert and almost dreams that he is in some wonderful garden. But there are no sparkling fountains and grassy lawns to complete the illusion; only the thorny shrubs with their vivid blossoms and the scorching sands, the dust, the thirst, and the cloudless sky above.

A very common species of cactus is the nopal or prickly-pear, the fruit of which is known as the tuna, and which is much prized both by Indians and by Mexicans.

A welcome plant to the desert traveler is the bisnaga, or "well of the desert." This is a cylindrical-shaped green plant thickly covered with sharp spines. By cutting out the center of the plant, a bowl is formed which quickly fills with water of an excellent quality, affording a palatable drink to the thirsty traveler. Many a life has been saved by these plants, and there have been a number of instances recorded where travelers, ignorant of the properties of the plant, have died of thirst in the midst of them.

Another cactus found in the southern desert is the grape cactus, which bears in clusters fruit resembling the tuna. The fruit is green without and purple within, is juicy, melting, and luscious.

A very common and ungainly plant is the ocotilla, growing clusters of straight poles from ten to fifteen feet in height, which are covered with spines. The poles terminate in long spikes of beautiful scarlet blossoms.

The maguey or mescal, sometimes misnamed the century plant, is common along the foothills bordering the desert. It is from this plant that the Mexicans and Indians distil the fiercely intoxicating drink known as mescal, which contains a large percentage of alcohol of a villainous quality.

From the cluster of spiked leaves, which attain a height of four or five feet, springs a pole ten to twelve feet tall, which bears large clusters of small yellow flowers filled with a sickishly sweet syrup. The maguey furnishes the native Indian with both food and clothing. From the fibers of the leaves he weaves coarse cloth, and the inner leaves, when stripped and cooked in the earth ovens by surrounding them with stones heated on coals, are considered a delicacy.
