[1] Died in 1878. The Century Co. published a small volume of his poems a few years ago. This poem has never before been printed.--ED. [Illustration: From col. Chi. Acad. Sciences. CACTI. 1/2 Life-size. Copyright 1898, Nature Study Pub. Co., Chicago.] THE CACTUS. PROF. W. K. HIGLEY. Because the Greeks in olden times applied the word Cactus to a prickly plant, Linnæus, often called the Father of Botany, gave the same name to our wonderful American growth and since his time these strange and varied plants have borne this nomenclature. We can hardly imagine any group of plants more interesting. There are over eight hundred varieties of curious and unexpected forms, bearing tubular or rotate flowers most varied in size and color--white, pink, purple, yellow, crimson, deep red--all beautiful and fascinating, and in our Northern country, protected in the conservatories. The Night-blooming Cereus is most renowned, most admired of all. The Cacti are commonly found in the United States, in Mexico, and in South America, and some species are cultivated on the borders of the Mediterranean Sea, where the fruit is eaten. They vary in size from an inch or two in height to enormous growths of fifty or sixty feet (_Cereus giganteus_) which stand like telegraph poles, sometimes nearly bare, sometimes with many vertical branches, reminding one of a huge candelabrum. Then again some forms are nearly spherical, while others are long, jointed, and square, one species (_Echinocactus visnaga_) grows about nine feet in height with a diameter of three feet or more and a single plant of this species will sometimes weigh a ton. One of our most common forms is flat and broad. This, the Prickly Pear or Indian Fig (_Opentia Vulgario_), is the only species found as far north as Wisconsin and New York. As many of the Cacti require but little care, they are quite extensively cultivated, not only for the rare beauty of their flowers, but for economic purposes. However, nearly all are worthy of culture because of their peculiar forms. In structure they are fitted for growth in the most arid regions; they abound in the deserts of New Mexico and southward, in many cases obtaining their food from a soil in which no other plant will grow, their thick coats enabling them to retain moisture and vitality for many weeks. Specimens of the Prickly Pear have been known to grow after lying on a dry floor, in a closed room, for six months and they have blossomed when left in this condition for some time. These plants, which are more or less succulent, are usually protected from the ravages of animal life by a formidable array of spines and prickles. Those who have carelessly handled our common Prickly Pear can attest to the intensely irritating character of its defensive armor. Thus does nature provide for the care of its otherwise defenseless forms.
