March 30th.—While in Buenos Ayres, we were indebted for repeated hospitality, at dinners and other entertainments, to the American Minister and other fellow-citizens from the United States, including my kind friends of the Methodist parsonage, where I was a constant guest.

We left on the 25th ult. The Montevideans exult greatly in the overthrow of Rosas; and, on our return, we found the citizens in the midst of public rejoicing, and various festivities. The 12th inst. was a grand gala for the reception of the troops of the Republic, which had been engaged in the battle of Monte Caseros. Among the most gallant of these was the negro regiment. A few days afterwards, I witnessed a religious ceremony of thanksgiving, at the cathedral, characteristic of the services of the church here, in which this composed the audience. Marching into the public square in two detachments, each led by a band, they formed in line, in front of the church, and entering it in military procession, filled its spacious nave. The bands took a stand on either side near the chancel. The soldiers, at the word of command, knelt with their arms reversed; the priest approaching the altar, opened the books and commenced the service, not by reading, at least not so as to be heard, but in pantomime. One of the bands, at the same time, began the performance of an opera, in which it was relieved at intervals by the other; while the bell of the priest gave signal, from time to time, to the soldiers, for the requisite smitings on the breast, crossings of the forehead, lips and chest, and bowings of the head. The music of the opera was continued without intermission for half an hour, till the performance at the altar was brought to a close; and then changed to a lively quick-step, to the gay movements of which, the troops again marched to their quarters.

The French Admiral, Lepredour, and the Brazilian Admiral, Grenfell, both received official intelligence from their respective governments by the last mail-packet, of their advancement from the rank of rear to that of vice-admiral, in acknowledgment of the importance of their services here. The 21st inst. was made a festival in the squadrons of both, as the day on which their new flags were first hoisted, when they received a salute from the vessels of their respective squadrons, from those of other nations here, and from the batteries on shore.

Admiral Grenfell, an Englishman by birth, and originally an officer in the Royal Navy, is greatly distinguished for his gallantry, and for many brilliant acts in the naval history of the South American States: first, under Lord Cochrane,—the present admiral, Earl Dundonald—in the Chilian Navy; and afterwards under the same officer in that of Brazil on the Atlantic coast. For twenty years past he has rendered most important service in the Imperial Navy; has had chief command on occasions of distinction and honor; and, still in the confidence of the Emperor, was called from the civil appointment of consul-general in England, to take command of the squadron sent to facilitate the operations of the allied forces of Entre-Rios and Brazil, against Rosas. This he successfully did, rendering abortive the defences which Rosas planned to prevent Urquiza and Caxias from crossing the Parana—thus removing the only obstacle in their march to Buenos Ayres. For this service, to the order of the Southern Cross, previously conferred on him, that of the Grand Cross of the Imperial Order of the Rose is added, and he promoted to the highest rank in the Brazilian Navy. He has been a regular attendant on the Sabbath in the chapel, in which I officiate on shore; and apparently is one of the most devout of the worshippers there, and one of the most attentive of my hearers.

Shortly after my return from Buenos Ayres, it was intimated to me that some appropriate notice of the important political events which had occurred, not only in the relief of Montevideo from siege, but in the overthrow of its most powerful enemy, would give satisfaction to the church and congregation. On the succeeding Sabbath, therefore, my discourse, in addition to such allusions as I thought proper to make—in regard to the affairs of the Republic of which this place is the capital—embraced the duty of Protestant Christians, resident in it, though not themselves citizens, towards the people and their rulers. The general tenor of my subject may be inferred from the text, “I exhort, therefore, first of all, that supplication, and prayers, intercessions and giving of thanks be made for all men: for kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty.” The practical application which I attempted to enforce will be most readily condensed by a quotation from a familiar hymn:

“So let our lips and lives express

The holy Gospel, we profess,

So let our works and virtues shine,

To prove the doctrine all divine.

Thus shall we best proclaim abroad
