AMERICAN COMMONWEALTH 



JAMES BRYCE, M.P., D.C.L., 



A ulhor of ' ' 7"/^!? I/ofy Roman Empire. ' ' 



" A work unique in scope, spirit, and knowledge. There is nothing like it anywhere, extant, — nothing that ap- 

 proaches it. . . . Every thoughtful American will read it." — New York Titnes. 



"We have here a storehouse of political information regarding America such as no other writer, American or other, 

 has ever provided in one work." — New York Tribune. 



" We have no hesitation in placing this book at the head of those which pretend to treat of our form of government 

 in theory and in its practical working." — N. Y. Evening Post. 



" One must look far and wide, through dozens of volumes, for anything like the information and the intelligent criti- 

 cism which are here to be found." — Boston Herald. 



" With very much more than the ordinary emphasis must it be said that ' The American Commonwealth ' deserves 

 a very careful reading among the 60,000,000 of Americans whom it concerns." — Morning Jotir7ial. 



" The event of the year in the literary world takes place to-day in the publication by Messrs. Macmillan of Mr. 

 Bryce's monumental work on 'The American Commonwealth.'" — Pall Mall Gazette. 



" Prof. Bryce himself is so well known in literature and in public life that any book from him is sure to be seriously 

 discussed. Especially is this true of an elaborate work on .American institutions."— G. W. S., in New York Tribune. 



■' This splendid work on the institutions of the United States will prove tK" great work of the year for all thoughtful 



readers in this country." — Washington Capital.

Insurance. 



DELAY IS DANGEROUS. 



We call attention to the new form of Accident (indem- 

 nity) Insurance policies, which are written by the Mer- 

 chant's Casualty Insurance Association, 2t Park Row, 

 New York City, John S. Purdy, Secretary. These policies 

 cover weekly allowances of from $io to $25, according to 

 occupation, at a cost of only %t a year exclusive of the 

 cost to join, which is $5 payable once only. The public, 

 as a rule, carry life insurance, and the ordinary accident 

 policies issued by companies, paying a ?um in case of 

 death, is not so desirable as one of these indemnity policies 

 in case of accidents, which are so plentiful in thj- fast age 

 with its railroad horrors, fast driving, electric wires and 

 other countless forms of danger to which the public is con- 

 stantly exposed. The fact of the Association having no 

 unpaid claims, and its having just passed an examination 

 by the Insurance Department of New York State, shows 

 that the management is liberal with its policy-holders 

 -and conservative in its action. The Association also de- 

 sires to secure energretic Agents in every village and town, 

 to whom territory and favorable terms will be given.
