Ere reaching the station of Paso del Cerro a great grove of carolina-trees rises majestically, and in the grateful shadow of the branches a long line of bullock-wagons, each vehicle loaded with the wool for which the region is noted, goes winding its way towards the station in the stolid fashion of such processions. Paso del Cerro is delightfully situated, facing as it does a range of hills whose surface is dotted with ranches that appear picturesque enough in the distance. Beyond this point lofty cliffs of rock soar aloft, pressing near to the line. In the nooks and crannies of the great walls are dwarf trees of fantastic shapes that make pleasant breaks here and there in the bare rock of the surface.

A little farther on the colour of the soil begins to undergo a transformation, and soon the red sandstone—the colour that is typical of the same, as well as the more northern, latitudes in the surrounding republics—is stretching everywhere to join with the green in dominating the landscape. A few more wayside stations, and then Rivera and the Brazilian frontier are drawing near, while the mountain ranges that mark the Brazilian territory are already in sight.

Rivera is a town of no little local importance, small though its extent may be as it nestles in a hollow in the midst of the hills. The soft pink of its buildings and the red of its roads and hillsides contrast delightfully with the green foliage and brilliant flowers with which the spot is so liberally endowed. Rivera, moreover, is a place that can lay claim to some quite notable characteristics of its own. It possesses, for instance, a magnificent avenue, the Sarandi, that stretches for over a mile, shaded by trees for all its length, from off the central portion of which lies the pretty little plaza.
