A lady, belonging to the Presbyterian Church at which I preached, kindly sent her carriage to take us about to see the city. We visited the new Roman Catholic Cathedral, one of the principal “lions.” It was begun in 1841, and, though used for public worship, is not yet finished. The building is a parallelogram of 200 feet long by 80 feet wide, and is 58 feet from the floor to the ceiling. The roof is partly supported by the side walls, and partly by two rows of freestone columns—nine in each row—at a distance of about 11 feet from the wall inside. These columns are of the Corinthian Order, and are 35 feet high, and 3 feet 6 inches in diameter. There is no gallery, except at one end, for the organ, which cost 5, 400 dollars, or about 1, 100l. sterling. The floor of the building is furnished with a centre aisle of 6 feet wide, and two other aisles, each 11 feet wide, along the side walls, for processional purposes. The remainder of the area is formed into 140 pews, 10 feet deep. Each pew will accommodate with comfort only six persons; so that this immense edifice affords sitting room for no more than 840 people! It is a magnificent structure, displaying in all its proportions a remarkable degree of elegance and taste. The tower, when finished, will present an elevation of 200 feet, with a portico of twelve Corinthian columns, six in front and three on either side, on the model of the Tower of the Wind at Athens.
