gei water simply by lapping these barrel-shaped reservoirs. It is true that the very uicy pulp of these cacti when mashed and pounded will yield a mucilaginous drink, but no one dying of thirst is likely to have the strength either to make this "water" or stomach it- Actually the Mexicans have found two slightly more practical uses for these Barrel Cacti, From the strong, hooked spines of some species the\ make fishhooks, and from the juicy pulp, flasored and boiled in sugar, they make the insipid ^cactus candy" so attractive 10 tourists.

When the plant is young, these spines are borne on prominent nipples, which later develop into strong ribs. The Blue Barrel E ingens, is also extremelv popular as its bluish globular body develops attractive purple bands when it reaches three or more inches in diameter. Another old favorite is £. horiionthalonius. the Eagle Claw Cactus, with its heavy recurved pink or red spines set off by a pale silvery-gray plant and handsome frilled pink flowers in summer.

The genus Feratfacrus (fee-ro-kak'-ttis). which contains the greatest number of Barrel Cacti, is well represented by such stout barrels as F. latispinus^ with intertwined clusters of broad, hooked spines topped by a crown of ribbon-like dark pink spines and blossoms. Other fine species are the Giant-spined Barrel, F. rectispinus, with hatpin spines to ten inches in length; the Fishhook Barrel, / wtstiienii; F nobilis, and

These cacti are perhaps most successful planted out of doors and are
