The different states of this part of South America, such as Entre Rios, Cordova, Santa Fe, Mendoza, &c. sent Members, to attend the congress in Buenos Ayres, empowering the government to act for them in the treaty with England; which, after considerable discussion, has been signed and ratified. Mr. Parish, attended by the vice-consuls and other gentlemen, went in state to pay his respects to the governor upon the occasion. The reception of the consul was, of course, flattering: the flag was hoisted at the fort, and a gun fired. The clause which caused most debate in the congress, was that of religious toleration. Some of the members seemed alarmed. It was, however, allowed, with free liberty for Protestants to build their own places of public worship. This is something gained from ancient prejudices. I have not, however, a high opinion of English devoutness in Buenos Ayres. We have now a sort of prayer, or methodist meeting, held in a private house. A captain of a Liverpool brig brought out some religious tracts, which he circulated, and hoisted the Bethel flag in his vessel: I fear he found Buenos Ayres an uncongenial spot for those subjects. Another article in this treaty which has given general satisfaction, is, that no British subject shall be compelled to military service. In any disputes upon this topic, the British have been the only foreigners who have stood forward to resist it; the others have remained passive spectators. On Sundays and holidays, the British and American consuls hoist the flags of their respective nations from the tops of their houses. The Buenos Ayres flag floats by the side of the American: Colonel Forbes, like a skilful manager, studies the taste of the town. I have noticed, that many of my countrymen, in their desire to visit their native land, still talk of returning to Buenos Ayres. They certainly must feel some attachment to a country in which they have lived happily for a series of years. Eight or ten years of absence from home makes a great alteration amongst our dearest friends; some are dead, and others are absent, or indifferent. In England, too, every one must be content to mix with the crowd. A great many of the English are perfect masters of the Spanish language, having obtained their knowledge of it by a long residence in the country, and by coming to it at a very early age. I have been surprised at the quickness with which English children learn it: in a few months they are able to carry on a conversation, whilst those of riper age take years to attain it. When a man gets near thirty years of age, he feels little inclination to study languages.
