The close of the year 1824 witnessed a great increase of crime in Buenos Ayres. An atrocious murder was committed by two black fellows, upon a Genoese, who kept a tin shop near the College church. The murderers were apprehended, and shot at the Retiro, and their bodies afterwards suspended upon a gallows. A boy, accessary to the fact (having let the villains into the house), escaped capital punishment, being under the age regulated by law: he was, however, present at the execution. Two fellows broke into the house of Mr. Nelson, an English merchant, and stabbed his man-servant in several places; an alarm being given, they effected their escape. The servant recovered from his wounds. Numerous other robberies have taken place; amongst which, Mr. Parvin, an American clergyman, and three of his friends, were stripped of their clothes, a short distance from town. The first execution in this country for forgery took place in February, 1825, upon the person of Marcelo Valdivia, who was shot at the Retiro. By the old Spanish law, a person convicted of forgery was condemned to lose his hand. This young man had been before sentenced to death for the same crime, but his punishment was commuted to exposure in the Plaza, imprisonment for eight years, and banishment for life. In July, 1824, he underwent the first part of his sentence, being seated in the Plaza for four hours, with the notes he had forged suspended from his breast. In prison, he committed other forgeries, including a forged order for his own release. The government have been highly applauded for their firmness in punishing this criminal. His friends applied to the British consul for his intercession, which was declined. Colonel Forbes, the American agent, was much censured for having, in 1821, interfered and saved a murderer from justice. A black woman was shot, for attempting the life of her mistress. The execution of a female is a rare thing in this country. Much as Buenos Ayres has improved in her jurisprudence, she has still a great deal to amend--that part which relates to committal before trial for civil offences particularly. The two following circumstances passed under my observation. Upon the first issue of paper money, some forgeries were detected. An English captain, West, of the brig _Fortune_, conversing on this subject at a tavern, remarked, that a forgery might easily be effected; and that the gentlemen in that line at home would not be long about such a thing. This was reported to the police; and he was sent to prison without examination, upon suspicion of knowing of the forged notes, and was not released for some days. In another case, Captain Harrison, of the brig _Asia_, was imprisoned nearly a month, for bringing a false report of Monte Video being blockaded; which was indeed partly true, Brazilian schooners of war having been off there, and sailed for Colonia.
