We determined to return the complaisance of the natives by giving a ball on board our ship to our acquaintances in Talcaguana, and some from Conception. My officers made every effort to surpass the Chilians in the elegance of their entertainment; and having been detained on shore during their preparations, and till the hour appointed for the ball, I was really astonished to see how much they had been able to achieve. The deck was changed into a large illuminated saloon, decorated with fine myrtle trees, luxuriant garlands, and bouquets of flowers of every colour, exhaling the sweetest perfumes, and appropriate transparencies in the background opposite the entrance. The cabins had been cleared for refreshment-rooms; and the musicians, concealed behind a curtain, were to pour forth their animating strains unseen by the dancers. The cheerful scene was rapidly filled with cheerful faces; graceful figures moved in the lively dances; and love and beauty alone seemed to preside within the joyous precincts. But suddenly a universal confusion and panic terror was spread among the company, and chiefly among the ladies. Some suspicious simpleton or mischievous wag had whispered that we had a design of secretly weighing anchor during this festivity, and sailing away with our beautiful prisoners. My friend Mendiburu, however, at length succeeded in banishing this ridiculous apprehension, and restoring tranquillity. Pleasure and confidence again reigned over the revels, till the sun stood high in the heavens; and like every other earthly enjoyment, even our ball drew to a close, though it bade fair to linger long in the recollection as well of our returning guests as of some of the young entertainers. The delightful weather tempted us, soon after this, to make an excursion to the opposite shores of the bay, and visit the ruins of the old town of Conception. Mendiburu was of the party, as were all of our scientific brethren, and as many of the officers as duty permitted to be absent. Very early, on a beautiful morning, we distributed our party in three large boats, and rowed, in two hours, to the destined point. We landed at the village of Pencu, which, like Portici upon Herculaneum, is built upon the ruins of the former town of Conception, and whose inhabitants live quietly and cheerfully over the graves of their unfortunate predecessors, and disturb themselves little with the thought, that the same fate may bury them one day in a living tomb. About fifteen houses, surrounded by gardens, lie scattered here over a lovely plain, watered by the small river St. Peter. Nature here appears more luxuriant and productive than at Talcaguana. The mountains which encircle this valley rise gently to a moderate height, and delight the eye by the freshness of the shrubs with which they are covered.
