JULY 5TH-DECEMBER 27TH, 1845.
EDITED BY J. C. ROBERTSON.
"Invention follow'd in her brilliant train,
From each new truth new usefulness to gain;
From all the elements Discovery drew
The inmost secrets veil'd from mortal view:
And apt Invention, watchful by her side,
Each, as it rose, to man's delight applied;
Employ'd the water, caught the unwilling wind,
And made strong fire the slave to stronger mind,
Mingled contending elements at will,
Curb'd and restrain'd, and made them each fulfil
Its destined purpose in her curious plan,
All for the service and the ease of man.
And, chief of triumphs, in a happier hour,
Chanced on the secret of the mighty power
That sleeps conceal'd in every drop that flows
Round the huge earth, or freezes in its snows.
Discovery smiled with wonder at the sight,
And brisk Invention seized it with delight.
And lo! puissant steam, a servant mild,
Titan in force, but duteous as a child,
Put forth for man a strength unknown before,
And raised with mighty arms the ponderous ore,
Plied the quick shuttles in the weaver's room,
Sparing his strength, while it enrich'd his loom;
Whirl'd its great wheels triumphant o'er the deep,
Though tides and winds were adverse or asleep;
And on the land, along the assisting rail,
Drove its hot chariot swifter than the gale."
