This is the full question:

Take up the White Man's burden--

Send forth the best ye breed--

Go bind your sons to exile

To serve your captives' need;

To wait in heavy harness,

On fluttered folk and wild--

Your new-caught, sullen peoples,

Half-devil and half-child.

Take up the White Man's burden--

In patience to abide,

To veil the threat of terror

And check the show of pride;

By open speech and simple,

A hundred times made plain

To seek another's profit,

And work another's gain.
