The 25th of May, 1810, is the æra of the independence of Buenos Ayres; the period when, the French armies having overrun Spain, the people of this city deposed the viceroy, and appointed a junta of nine as a provisional government. This event is annually commemorated by a festival of three days. It commences on the evening of the 24th, when the Plaza is illuminated, by means of a lofty circle, formed of wood-work, erected round it. At sunrise on the 25th, the national hymn is sung by boys, &c. opposite the pyramid in the Plaza: to hail the rising sun is a Peruvian custom. In the day-time, various sports take place: greased masts are erected, at the summit of which are shawls, watches, and purses of money; and whoever can reach the top, may take any one of the above prizes. An English sailor, in 1822, brought down all the stock in trade, wrapping the shawls about his body, and putting the watches, money, and other articles, in his pockets and mouth. On his descent, he was surrounded by soldiers, who took away his booty; and on Jack making a shew of resistance, they marched him to prison. The bystanders, however, were indignant at this, and he was soon released, and allowed to retain one of the prizes. These masts cause great diversion, as very few succeed in mounting them; and our sailor was highly applauded. There is also an ingenious machine, called _rompe cabeza_, or break head, consisting of a pole placed lengthwise on pivots, elevated from the ground, with a cord on which to rest the feet. The difficulty is in getting along this pole; in doing which, hundreds are thrown off: the successful candidate obtains a piece of money. Military music plays at night in the galleries of the Cabildo; and fire-balloons and fire-works are let off, the latter emitting their balls of fire among the people. From the careless manner in which the fire-works are used by boys in the streets, I am surprised that no accidents happen. The theatre is open every night of the holidays, and is always crowded; the anthem is sung; and they have extra lights, &c. The governor and his suite attend. In the College church, on the 25th of May, prizes are distributed to those young females who have excelled in any particular branch of their studies. The ladies of the town take great interest in this, and attend the church in crowds. The organ performs during the ceremony, as well as other music. In 1821, the rejoicings went off gloomily, with little or no preparations.
