Humanity is always meeting obstacles. All honor to the men who do not fear obstacles, but push them aside and press on. Stephenson was explaining his idea that a locomotive steam engine could run along a track and draw cars after it. "But suppose a cow gets on the track," some one objected. "So much the worse," said Stephenson, "for the cow."

Men of thought! be up and stirring,
Night and day;
Sow the seed, withdraw the curtain,
Clear the way!
Men of action, aid and cheer them,
As ye may!
There's a fount about to stream,
There's a light about to gleam,
There's a warmth about to glow,
There's a flower about to blow;
There's midnight blackness changing
Into gray!
Men of thought and men of action,
Clear the way!

Once the welcome light has broken,
Who shall say
What the unimagined glories
Of the day?
What the evil that shall perish
In its ray?
Aid it, hopes of honest men;
Aid the dawning, tongue and pen;
Aid it, paper, aid it, type,
Aid it, for the hour is ripe;
And our earnest must not slacken
Into play.
Men of thought and men of action,
Clear the way!

Lo! a cloud's about to vanish
From the day;
And a brazen wrong to crumble
Into clay!
With the Right shall many more
Enter, smiling at the door;
With the giant Wrong shall fall
Many others great and small,
That for ages long have held us
For their prey.
Men of thought and men of action,
Clear the way!

Charles Mackay.
