As New-York was the first maritime city that built a chapel expressly for seamen, so it was the first to build a floating church, for although there had been previously in London and Liverpool old hulks fitted up as chapels, and moored in the docks for the use of sailors, there had never been an actual church edifice put afloat before the FLOATING CHURCH OF OUR SAVIOUR, which now lies moored at the foot of Pike-street, in the East River. This novel edifice was finished and consecrated in February, 1844. It is under the charge of the Young Men's Church Missionary Society of the City of New-York, by whom it was built, and has been under the pastoral care of the Rev. B. C. C. Parker, of the Episcopal church, from its consecration to the present time. It is seventy feet long, and thirty feet wide, and will comfortably seat five hundred persons. It has an end gallery, in which is an organ. A beautiful baptismal font of white marble, in the shape of a capstan, surmounted by a seashell, chiselled from the same block with the shaft--the gift of St. Mark's church in the Bowery, New-York--stands in front of the chancel rail. The top of the communion-table is a marble slab, and the Ten Commandments are placed on the panels on each side in the recess over it. An anchor in gold, painted on the back-ground between these panels, rests upon the Bible and prayer-book. The roof, at the apex, is twenty-six feet high, and eleven feet at the eaves. The edifice is built on a broad deck, seventy-six by thirty-six feet, covering two boats of eighty tons each, placed ten feet apart. The spire contains a bell, and the top of the flag-staff is about seventy feet from the deck. Divine service is regularly performed on Sundays, commencing in the morning at half-past ten, and in the afternoon at three o'clock. Both the boats on which the edifice rests are well coppered, and protected from injury by booms placed around them. [Illustration: THE FLOATING CHURCH OF OUR SAVIOUR.] A similar floating church has been built and moored near Rector-street, in the North River, near which is another floating chapel, formed of an old hulk, after the manner of the first floating chapels in London. In addition to these houses of worship for seamen, there is a large and handsome church for sailors near the "Home," in Cherry-street, under the charge of the Baptists, and a small seamen's chapel in Brooklyn, near the Catharine Ferry. To complete this system of benevolent enterprises for the benefit of sailors, there is a Seaman's Savings Bank in Wall-street, a very handsome structure of brown free-stone, in the third story of which are the offices of the Seaman's Friend Society.
