North of Tucuman are the provinces of Salta and Jujuy, both of which reach to the borders of Bolivia. To the west of Tucuman lie the provinces of Rioja and Catamarca, as well as the territory of Los Andes, all of which border Chile. These are all mountainous states, but they are neither small nor unimportant. The smallest one is as large as Massachusetts, Rhode Island and Maryland, and the largest one, Salta, is nearly as large as all of New England. The altitude of the towns varies from Rioja, the capital of the province of the same name, at an altitude of only seventeen hundred feet, to Jujuy, capital of that province, which lies four thousand two hundred and seventy feet above sea level, and is the highest city in the republic. Jujuy is distant just about one thousand miles from Buenos Aires by railroad, and is at the foot of the spurs of the range of mountains that reach up into Bolivia. Although so near the Tropic of Capricorn yet the elevation prevents the extreme heat that prevails in the lowlands during the summer, while the freezing point is never reached in winter. The scenery in the neighbourhood of this city is really beautiful, for hill and valley, wood and plain all contribute to make up an enchanting landscape. When the connection with the Bolivian railway is completed this city will be on another transcontinental line from the Atlantic to the Pacific. The territory of Los Andes, in the extreme northwestern corner of the country, is the most mountainous section and is very little known. The provinces of Cordoba and Santa Fé are the home of many beautiful birds. One of the most gorgeous of humming-birds is to be found here. Its body is green streaked with gold, with a vivid scarlet tail. A common song bird is the _bien te veo_ (I see you well), so named because its song is supposed to represent those words. The call, which is an extremely musical one, is repeated over and over again. It is brightly coloured and is a species of thrush. The oven-bird is a favourite bird and is looked upon much as the robin with us. It is chiefly remarkable for its nest, which is built of mud and is entered by a doorway. The nests are usually built upon any convenient post, and in places one will find half of the telephone and telegraph posts surmounted by one of these nests. It is a common saying that the oven-bird will not, under any consideration, build its nest on a Sunday. There are many birds of the vulture tribe in Argentina. Patagonia is especially a wonderful country for these birds of prey. Of these the chinango is a small carrion-hawk of a brown-gray colour. Another is the carancho, which is very common throughout the Camp. This bird is a dark brown with a light band across the wings. These two birds prefer carrion, but will attack enfeebled and helpless small animals such as hares or lambs.
