Who is kipling talking to when he says "send forth the best ye breed"? who does kipling mean when he refers to "your new caught, sullen peoples/half-devil and half-child?

In the first line, Kipling is talking to the nation's best men. These men are going to take control of the Philippines from the Spaniards. In the second line, Kipling is referring to the natives of the colonies. Some white people regard the uncivilized natives as half-devils because of their religious beliefs.
