The plant consists of an aggregation of thick, flat, oval leaves, which are joined together by narrow bands of woody fiber and covered with bundles of fine, sharp needles. Its pulp is nutritious and cattle like the young leaves, but will not eat them after they become old and hard unless driven to do so by the pangs of hunger. In Texas the plant is gathered in large quantities and ground into a fine pulp by machinery which is then mixed with cotton-seed meal and fed to cattle. The mixture makes a valuable fattening ration and is used for finishing beef steers for the market. The cholla, or cane cactus, is also a species of Opuntia, but its stem or leaf is long and round instead of short and flat. It is thickly covered with long, fine, silvery-white needles that glisten in the sun. Its stem is hollow and filled with a white pith like the elder. After the prickly bark is stripped off the punk can be picked out through the fenestra with a penknife, which occupation affords pleasant pastime for a leisure hour. When thus furbished up the unsightly club becomes an elegant walking stick. The cholla is not a pleasant companion as all persons know who have had any experience with it. Its needles are not only very sharp, but also finely barbed, and they penetrate and cling fast like a burr the moment that they are touched. Cowboys profess to believe that the plant has some kind of sense as they say that it jumps and takes hold of its victim before it is touched. This action, however, is only true in the seeming, as its long transparent needles, being invisible, are touched before they are seen. When they catch hold of a moving object, be it horse or cowboy, an impulse is imparted to the plant that makes it seem to jump. It is an uncanny movement and is something more than an ocular illusion, as the victim is ready to testify. These desert plants do not ordinarily furnish forage for live stock, but in a season of drought when other feed is scarce and cattle are starving they will risk having their mouths pricked by thorns in order to get something to eat and will browse on mescal, yucca and cactus and find some nourishment in the unusual diet, enough, at least, to keep them from dying. The plants mentioned are not nearly as plentiful now as they once were. Because of the prolonged droughts that prevail in the range country and the overstocking of the range these plants are in danger of being exterminated and, if the conditions do not soon change, of becoming extinct.
