A mail arrived yesterday ...
A inail arrived yesterday from Buenos Ayres, with letters to the 26th of June. By this packet hag come passenger M. fRVAI)AVIA, through whose wiscadministration for the last four years that State has been enable(d to make sRAch rapid advances in prosperity. He wvas in fact at the hcad of the Governmnent, though he bore only the title of Prin- cipal Secrctary or State. It is said that IM. RIVADAVItA hNu entirely ciosed his political career *vith his resignation of his late office, antI that he intends to retire to private life; but it is obvious that his residtence here or in any part of Europe rnay, by the very general knowledge of, and Gonfidence in, his character, be tmade productive of great good to Bucnos Ayres, as well as to the grcat cause itself oflSoutl Atnerican inflopendencc. 'I'hc fol- lowing is an extract. from the Buenos Ayres paper entitled ThLe Arqos, of the 23d of Jtnc, which cat-eby thc snme con- veyance:-"Among the various articles of intelligence coin- municated from Salta by the last courier, wlho arrived at the end of the preceding week, is the report that in Cabija, a port of Atacama, had disembarked General MIILLER, belonging to the Army of Independence, with the title of General of the Vanguard. In this army werc expected 2,SOO destined to act against the Royalist General Ot.ANETA. It is positively stated, likewise, that Brigadier ESPARTERO, the par- tieular friend of General LA SERNA, anl mnuch co:1]- promise(d in the plans of command in which that Ge- neral insists, under contlition of playittg tlte prin- cipal part, ha(d embarked under pretext of procee(ling to Spaini, but with the real object of going to another qiiarter to combine plans of importance. By the same convoy it is communicated, that the Constitutional General VAL.DE7, having been much weakened in Mora, had been conducted to La Paz, where he died in a few days. If this newvs be true, OLAN ETA has lost one of his principal rivals, FERDINAND VII. one of his greatest enemies, and the cause of independence one of its most zealous supporters."
