158 STAINED GLASS AT NORBURY MANOR HOUSE. 
until the idler and the frivolous are no longer to be found. The 
great changes wrought during the last fifty years—one of the 
most remarkable periods in the world’s history—by the discovery 
of steam as a motive power, and the consequent greater facilities 
of inter-communication with all parts of the world, have rendered 
universal knowledge of all kinds a real necessity ; and however 
much the mind may be staggered by such immense changes, the 
end of them has not yet come. Still greater and more important 
ones are on the way, as is evident by the advances already made 
in bringing into use the wondrous power of electricity. This 
once accomplished as a motive power—and there seems no limit 
to the changes that will result from it—the advantages in every 
way will be so immense, we again turn our eyes upon these 
pieces of painted glass, and rub them, and wonder whether or 
not this is all a dream.
