At San Pedro the steamer emerges from the Parana de las Palmas and enters the main channel of the river. A notable locality a few leagues above San Pedro is the Obligado, where the Parana becomes so narrow that the channel lies within pistol-shot of the right bank. The Obligado is interesting in an historical point of view as having been the scene in 1845 of a fierce engagement wherein the English and French fleets ran the gauntlet of the Argentine batteries there, which attempted to prevent their passage. One of the English vessels, under a withering fire, cut a chain that barred the channel. A humorous sequel to this brilliant feat of arms is this, that since that occurrence every French sailor, and especially every deserter from the French merchant marine who goes to La Plata, boasts that he "assisted" at the affair. He will narrate all the details in the most bombastic manner to any pecuniarily prosperous fellow-countryman who will listen to him, and will then close with a proposition that he and his compatriot shall "take something." The payment for the score naturally falls to the lot of the listener or victim, and hence has arisen a saying among Frenchmen in La Plata: "Distrust the gentleman who was at the combat of the Obligado."

Twenty-four hours after leaving Buenos Ayres the steamer stops at Rosario, having previously passed the town of San Nicolas de los Arragos, with its ten thousand inhabitants, its picturesque cathedral flanked with a white tower on either side, its progressive tramways or horse-cars, and its reputation for furnishing an excellent article of hides, the province being celebrated for the quality of its cattle.

Rosario is the second port of the confederation. It stands a short distance away from the river on a barranca or cliff. Passengers on landing are conveyed in horse-cars to the town, which is laid out in handsome streets and built up with charming and comfortable houses. The barn-like church, of the "horrible Jesuit style," as M. Forgues calls it (the heavy style of architecture common to nearly all the church edifices of South America), is very ugly, and as to the "faithful élégantes" who worshiped in it, our traveler did not deem them as handsome as their sisters of Buenos Ayres. Much of Rosario's increasing prosperity is owing to the railroad which connects it with the interior town of Cordova to the west. This road also extends down the Parana to a point about half-way to Buenos Ayres. When completed to the latter city and to its western terminus, which will be at no distant day, Buenos Ayres, on the Atlantic, will be connected with Valparaiso, in Chili, on the Pacific. There is also a line of English steamers which ply directly between Rosario and the English ports.

At Rosario the Republica takes on passengers, coal and freight, and resumes her voyage. Above the city, the cliffs, increasing in height, attain an altitude of nearly one hundred and fifty feet. They are composed entirely of a hard brown earth having the appearance of pulverized chocolate; and the river, rushing between them, assumes a dirty, brownish hue for many miles. In their shadow, as the steamer passes, lie a Brazilian gunboat and two monitors of the same nationality: one of the latter is deeply dented in places where she was struck by Paraguayan cannon-balls.

PUBLIC SQUARE IN PARANA.

About twelve hours' distance from Rosario the Diamante, or Diamond Cliff, is reached. Here the cliffs that line the left bank culminate. They are especially interesting to the geologist because of their extraordinary richness in fossils of various kinds. Fragments of the megatherium and of the glyptodon have been found there, but the most important discovery of all was a very complete skeleton of the former animal—the most complete in existence, in fact—which now adorns the museum at Buenos Ayres. The village of Diamante, with a population of five or six hundred souls, is situated near by. Twenty hours later the Republica arrives at Parana, a handsome city, formerly the capital of the confederation. The removal of the seat of government to Buenos Ayres was a great blow to the prosperity of the old capital. Once the diplomatic corps had their residences there. The climate of the place is delicious, and under its balmy influence the orange tree flourishes in the open air and bears fruit of exquisite flavor. The country around Parana is very picturesque, and the town itself, though since it has ceased to be the Argentine capital it presents an appearance of emptiness, is very gay. Among its attractions are a theatre and a fine public square adorned with shade trees. The community has musical tastes, and nearly every second house contains a piano—a fact of which the stranger strolling through the place is kept constantly aware. Many of the streets are paved and macadamized.

A BLANCO INSURGENT.

Parana is the chief city of the province of Entre Rios, the people of which are possessed of a fierce spirit of independence, and, like the Basques of Spain, claiming the right to administer their domestic affairs in their own way, they are often in insurrection against the central government at Buenos Ayres, which resorts to force to check their "separatist" tendencies. Within four years two or three efforts at revolution have been made on the part of the people of Entre Rios under Lopez Jordan, their principal leader, General Mitre, and others. One year previous to the journey we are now describing our traveler had gone from Buenos Ayres to Parana on business. In consequence of a municipal election having gone in favor of the government candidates by a majority of thirty votes, a fresh insurrection had just broken out in the city, and when M. Forgues reached his destination he found the national troops in possession of Parana, which was closely besieged by the Blancos or "Whites," as the insurgents were called from their trappings, to distinguish them from the Colorados or "Reds," which was the name given to the Buenos Ayres party. On the occasion of this visit he had need to seek the insurgent camp in furtherance of his mission, which was to obtain possession of eight thousand hides that were within the insurgents' lines. He returned to Parana, after successfully conducting the negotiations, with a sketch of one of the mounted Blancos, a picturesque, stately fellow, with the proud bearing of a brigand, having enormous spurs on his heels, a white band around his hat, and armed with a lance and a long cavalry sword.
