Also, the camel is now fairly naturalized in Texas and New Mexico, and the two-toed ostrich in South America; on the pampas of that continent travellers may meet with the gazelle, the springbok, the oryx, and the kangaroo. Elephants are domesticated and used for court occasions in Brazil, as they are in India. Tea and coffee are now largely cultivated in California, Georgia, Tennessee, North Carolina, and Virginia. In exchange, the cinchona tree abounds more now in India than in Peru, and the cacao or cocoa tree has been planted by thousands upon the southern slopes of the Himalayas and in Persia. On the other hand, the bison and the prong-buck are almost extinct in the west. But for the great national parks, Yellowstone, Yosemite, Niagara and others, carefully guarded, the American deer, elk, and moose would all likewise disappear. Forest-culture, however, is, by the pressure of necessity, attracting, as it ought, a great deal of attention, under the guidance of the government Agricultural Department. * * * * * It seems to work well, better than some expected, to have our national Cabinet enlarged by the introduction to full rank in it of the three new Secretaries, of Agriculture, Education, and Health. The importance of the last named of these is universally acknowledged; as well as the necessity for State Boards of Health in all the States. * * * * * How much sanitation has advanced during the last half century! Human life now averages 50 years in the United States; rather more in England, and nearly as much in France and Germany. By stringent regulations for maintaining cleanliness of ships, wharves, and, indeed of cities throughout, along with the abolition everywhere of the useless and detestable antiquated personal quarantine, yellow fever has been almost absolutely extinguished; only ten deaths from it occurring last summer in Havana, one or two in Pensacola, and not one in New Orleans, Memphis, Nashville, or any other city in the United States. Cholera, likewise, through sanitary improvements, has disappeared from the world, except a score or two of cases annually in the worst crowded villages near the Ganges in India. What a grand triumph of medical art, also, following Jenner's vaccination, and Pasteur's later investigations, is the protection afforded against the dangers of scarlet fever, measles and whooping-cough, by inoculation with a modified virus, appropriate to each!
