Rh waste. The great naked mountains and the leafless character of much of the vegetation give to some portions of Mexico a sterile appearance which always makes an impression on strangers. Some varieties of prickly pear grow to the size of quite large trees. The fluted columns of the organ-cactus tower up to the height of sixty feet in favorable soil. The prickly-pear cactus is

used for hedges, and, as it bristles with thorns and spines, intruders are kept at a respectful distance. The Indians, who are very fond of the fruit of this cactus, go out in August, when it is ripe, and hook it down with forked sticks. Mexico seems to be the home of the cacti. Their grotesque forms are seen everywhere, brightened in their season with beautiful blossoms—pink, pale-yellow, warm tints of red or deep gold.
