INTRODUCTION 



To the white races this great responsibility has been 

 entrusted. Shall the work of Christianity be carried 

 through with unstained hands or with guilty red ones ? 



As it has been carried on so far the work is no credit 

 to the pages of nineteenth and twentieth century history. 



Time alone can prove, and the moral responsibility 

 rests not alone with us to-day, but with the next few 

 generations to come. 



R. D. C.
