No book published in this country for many years contains more of interest to th 

 American whose public career extends back fifty years. 



" Keen, Clear and Accurate." 



" Hardly any other volume of contemporary memoirs is entitled to 

 greater consideration than this. There is a great deal of insideness to 

 these reminiscences. They come from one whose judgment was keen, 

 clear, and accurate, and whose opinions are entitled to great weight. 

 We have had political reminiscences, and the story of the war has been 

 told by some of the great Commanders, but it is doubtful whether any 

 other volume on public affairs is more informing and reveals more of 

 what at the time were state secrets than this one." 



" A Si..t Ji.-.^^ . Work." 



"Mr. McCulloch modestly em. les his work ' Sketches and Com- 

 ments. ' But the sketches are so sharp in outline, so positive in feature ; 

 the comments are so explicit and delivered with so ex catkedra an air of 

 personal observation and infallible accuracy that the volume must become 

 one of the standard works in the history of our time." — Cliicago Tribune. 



"The book breathes throughout the high and generous character of 

 its author, and is a most valuable contribution to the political history of 

 the time." — New York Tribune. 



" One of the most valuable 

 tions to the historical literatun

 G. Underwood, Missionary in Corea since 1SS5. 



". . . It is sure to be the book of reference for Corea for years to 

 come." — S. R. Carles, /i^. B. M. Vice-consul in Corea, 1884-1886.
