After seeing the handsome, dark-eyed boys of the college, its fine library and other interesting apartments, I ascended with Father Osoro to look at the observatory en the top of the building. This solid and business-like structure possesses the newest and most complete astronomical and meteorological instruments, and the accuracy of the scientific results arrived at by the Fathers, has become justly celebrated. They received a manifestation of merit from the Centennial Exposition of '76, on account of their meteorological observations, and the Parisian Exhibition presented them with a magnificent medal. Father Benito Vines, the president, communicates regularly with Washington and nearly every civilized nation. After viewing the interior of the observatory, we came out on the roof, and here I beheld a novel and wonderfully lovely sight. Stone and brick walks, four or five feet wide, with railings at each side spread away, intersecting each other at different points, and all were above the dark, red-tiled roofs of the institution. Strong little edifices like watch towers, painted in blue and white, stood out prominently near the walks, and no sooner did the eye turn from these immediate objects, than it was dazzled by the superb panorama of city, ocean, bay, sky and woodland that spread before it. Father Osoro enjoyed the expressions of admiration that escaped me, as I gazed on the high and low roofs on every side, the black turrets, the walls of houses, red, green, blue, crimson, yellow, and white all mellowed by age. Down below us were the narrow streets, the iron-barred windows, the curious shops, verandas, balconies, flag staffs, flying pigeons, flowers blooming on the roofs, and bananas growing. Away to the north-east stood the grand Morro Castle, the sentinel of the harbor, with its frowning guns, and its grand, revolving light shining like a gem above the sea. Behind it, Fort Cabana looked long, bold and ancient, backed on the east by evergreen hills, and decorated on the south by palms and other tropical trees. The harbor, which glittered with sunlight, was full of ships, buoys, sail-boats, music and sailors. On this side of the bay appeared the old cathedral, with its dark gray walls and black and brown roof. Yellow pillars, old towers, picturesque wind-mills, brown iron stairs running up to the roofs of mansions, palaces, domes, cupolas, plants of great beauty in vases on roofs, and numerous old spires intervened. On the right, near the bay, could be seen the old church, de San Francisco (now a customs storehouse), the church de San Augustin, the church de Sancto Spiritu, and the palace of the admiral to the south, the church de Mercede, that of St. Paul, the arsenal, military hospital, gas houses, the Castello de Princepe, and the suburban gardens of the captain-general. On the north, we beheld the ocean, the Castello de Punta and the Casus de Benefecentia. The Campo de Marte, Parque de Isabella, the parade grounds, trees,
