I heard the congregation singing hymns of praise to-day; the loud organ led them on, binding all together, so that the voices were as the voice of one man; the grand chorus filled the house of the Lord; it seemed to say Holy, holy, holy is the Lord of hosts! let the whole earth he filled with his glory; and I came away wishing that the people of America could hear it too, hear it until they should know what we mean when we speak of congregational singing, become sensible of its immense importance to their worshiping assemblies, and hasten to take the appropriate preparatory measures for its introduction.
