Palm Sunday opens the ceremonies. We drove to the Vatican this morning, at nine, and, after waiting a half hour in the crush, kept back, at the point of the spear, by the Pope's Swiss guard, I succeeded in getting an entrance into the Sistine chapel. Leaving the ladies of the party behind the grate, I passed two more guards, and obtained a seat among the cowled and bearded dignitaries of the church and state within, where I could observe the ceremony with ease. The Pope entered, borne in his gilded chair by twelve men, and, at the same moment, the chanting from the Sistine choir commenced with one long, piercing note, by a single voice, producing the most impressive effect. He mounted his throne as high as the altar opposite him, and the cardinals went through their obeisances, one by one, their trains supported by their servants, who knelt on the lower steps behind them. The palms stood in a tall heap beside the altar. They were beautifully woven in wands of perhaps six feet in length, with a cross at the top. The cardinal nearest the papal chair mounted first, and a palm was handed him. He laid it across the knees of the Pope, and, as his holiness signed the cross upon it, he stooped, and kissed the embroidered cross upon his foot, then kissed the palm, and taking it in his two hands, descended with it to his seat. The other forty or fifty cardinals did the same, until each was provided with a palm. Some twenty other persons, monks of apparent clerical rank of every order, military men, and members of the Catholic embassies, followed and took palms. A procession was then formed, the cardinals going first with their palms held before them, and the Pope following, in his chair, with a small frame of palmwork in his hands, in which was woven the initial of the Virgin. They passed out of the Sistine chapel, the choir chanting most delightfully, and, having made a tour around the vestibule, returned in the same order. The ceremony is intended to represent the entrance of the Saviour into Jerusalem. Bishop England, of Charleston, South Carolina, delivered a lecture at the house of the English cardinal Weld, a day or two ago, explanatory of the ceremonies of the Holy week. It was principally an apology for them. He confessed that, to the educated, they appeared empty, and even absurd rites, but they were intended not for the refined, but the vulgar, whom it was necessary to instruct and impress through their outward senses. As nearly all these rites, however, take place in the Sistine chapel, which no person is permitted to enter who is not furnished with a ticket, and in full dress, his argument rather fell to the ground.
