The Camel and the Drift-Wood

The first who saw a real live Camel
Ran for his life; the second ventured near;
The third, with ready rope, without a fear,
Made a strong halter the wild thing to trammel.
Habit has power to quickly change
Things that at first seem odd and strange;
Stale they grow, and quickly tame,
And hardly seem to be the same.
And since the question's open, once there stood
A look-out watching all the distant flood;
And seeing something far off on the ocean,
Could not conceal his notion
It was a man-of-war; a moment past
It turned a fire ship, all ataunt and brave,
Then a big boat, and next a bale, and last
Some mere drift timber jostling on the wave.

How many things watched by the world agree
In this--that far away you see
That there is something, yet when sought,
And seen still nearer, it proves nought.
