The city of Mendoza, which, according to Bauza, is in south latitude 32° 52´, west longitude 69° 6´; at an elevation of 4891 feet above the sea, and at the very foot of the Andes, is shut out from any view of the great Cordillera by a dusky range of lower hills which intervene. Its appearance is neat and cheerful: the houses, for the most part, built of sunburnt bricks, plastered and whitewashed; and the streets laid out at right angles, as usual in that part of the world. It boasts of an Alameda, or public walk, said to equal anything of the kind laid out, as yet, in South America:--it is nearly a mile long, neatly kept, and shaded by rows of magnificent poplars:--there are seats and pavilions at either end for the accommodation of the inhabitants, by whom it is much frequented as a lounge, especially of an evening. The climate is delightful and salubrious, and is remarkably beneficial to persons suffering from pulmonary affections. The only ailment to which the people seem more liable here than in the interior is the goitre, which I suppose may be attributed to the same causes, whatever they are, which seem to produce it in almost all alpine districts. SAN JUAN. The province of San Juan, which adjoins that of Mendoza, occupies the space between the great Cordillera and the mountains of Cordova, as far north as the Llaños, or plains, of La Rioja. It is said to contain about 25,000 inhabitants, governed, at present, like those of Mendoza, and occupied very much in the same manner, in the cultivation of their vineyards and gardens, and in agricultural pursuits. Their exports of brandies and wines to the other provinces are little short of those from Mendoza, and the quantity of corn they annually grow has been estimated at from 100,000 to 120,000 English bushels. The same lands produce yearly crops under the process of artificial irrigation from waters highly charged with alluvial matter. The ordinary crops are 50 for 1, in better lands 80 to 100, and in some, as at Augaco, about five leagues to the north of the city of San Juan, they have been known to yield 200 and 240. The price in the province is from one and a half to two Spanish dollars for a fanega, equal there to about two and a half English bushels. The wages of a day labourer are from five to six dollars a month, besides his food, which may be worth a rial a day more.
