San Juan is insignificant in point of size, but its population seems to be well to do in the world, in the relative sense in which that term is to be interpreted in Central America. Here we found that the river forks,--the principal branch, however, which retains the name of Goascoran, still preserving its general course north and south. The smaller branch, called Rio de San Juan, descends from high mountains to the westward, having its rise, we were told, near the secluded Indian _pueblos_ of Similaton and Opotoro. We found the elevation of San Juan to be nine hundred feet above the sea,--an altitude sufficiently great, combined with the proximity of the Cordilleras, to give it a generally cool and delightful climate. The change in temperature from that of the sea-coast, however, is less marked than the change in scenery and vegetation. It is true, we find the ever-graceful palm, the orange, plantain, and other tropical fruit-trees; but the country is no longer loaded down with forests. It spreads out before the traveller in a succession of swelling hills and level savannas, clothed with grass, and clumped over with pines, and miniature parks of deciduous trees, sufficiently open to permit cattle and horsemen to roam freely in every direction. During the dry season, however, this open region becomes dry and parched, and the traveller passing over it then would be apt to pronounce the whole country sterile and without cultivation. But in little lateral valleys and _coves_ among the mountains, sheltered from the sun, and watered by springs or running streams, there are many plantations of sugar-cane, maize, rice, and other standard products of the tropics, of unsurpassed luxuriance. We sometimes came on these green places unexpectedly, far away from any habitation, and all the more gem-like and beautiful from their rough setting of sere savanna and rugged mountain.
