The German Biological Justification of the World War 



is clearly set forth and refuted in 



By VERNON KELLOGG 



When the war broke out, Professor Kellogg was a neutral, a pacifist, and an admirer of 

 Germany. In the hope of relieving human suffering, he left his chair at Leland Stanford Uni- 

 versity, went to Europe, and became special envoy of the Committee for the Relief of Belgium 

 at German General Headquarters emd at the headquarters of General Von Bissing in Brussels. 



For many months he lived on intimate terms with the leaders of the German armies in 

 the West. He woriced with them, dined with them, argued with them, heard them expound the 

 creed of the Allmacht in defense of their aims and conduct. 



Headquarters Nights not only gives an impressive and revolting picture of the 

 workings of German militarism among the people it has crushed, but it meets the exponents of 

 ifuHur on their own biological ground. In the " confessions of a converted pacifist," Professor 

 Kellogg proves that "Germany must be converted to be a good Germany or not much of cmy 



Germany at all Resistance by brutal force ; war to a decision. It is the only argument 



in rebuttal comprehensible to these men at Headquarters, into whose hands the German people 

 have put their destiny."
