Through some halls and corridors back of the grand altar is the chapel of "Our Lady of the Sacred Heart," which is one of the most beautiful sanctuaries in the city, and remarkable for the harmony of its lines and proportions. It is in the form of a cross, ninety feet in length, eighty-five feet in the transept with an altitude of fifty-five feet. The splendour of its ornamentation, carving, sculpture, elegant galleries, panels in mosaic, original paintings by Canadian artists, and a beautiful reproduction of Raphael's celebrated frieze of "The Dispute of the Blessed Sacrament," unite to constitute this piece of ecclesiastical architecture a _chef d'oeuvre_. An iconoclast might marvel at the absorption in prayer of some of the devotees, among accessories bewildering to eyes accustomed to the plainer surroundings of other forms of ritual, but the worship of those in attendance seems sincere and complete. Following the footsteps of Cartier to where, near the foot of Mount Royal, he found the Indian village of Hochelaga, is now to be seen the St. James' Cathedral, which is a reduced copy of St. Peter's at Rome, the great centre from which radiates the Catholicism of Christendom. It is somewhat less than half the dimensions of its model, with certain modifications necessary in the differences of climate. The work was entrusted to M. Victor Bourgeau, who, to gain the information necessary to carry out successfully a repetition of the great master, Michael Angelo's conception, spent some time in the Eternal City studying the various details. But the real architect, it may be said, who made the plans and supervised and directed the building of the sacred monument, was Rev. Father Michaud, of the St. Viateur Order. To raise the funds necessary for the initial work, every member of the immense diocese was taxed; and even now, after a lapse of thirty years, it is still unfinished, so great has been the expense involved. The handsome facade is elaborately columned in cut-stone, for which only blocks of the most perfect kind were used. Like the colossal dome at Rome, this one towers above every other structure in the city, with the height of the cross included, being forty feet higher than the lofty towers of _Notre Dame_. It is seventy feet in diameter, and two hundred and ten feet above the pavement. It is after the work of Brunelleschi, whose exquisite art and genius flung the airy grace of his incomparable domes against Florentine and Roman skies.
