KING'S HANDBOOK OF BOSTON. 



COMPLETE AND READABLE. 



In making new editions of his Handbook of Boston, Moses King, the 

 editor and publisher, has invariably revised, enlarged, and improved the 

 book every time, so that although the general character and appearance 

 remain the same, the contents are decidedly altered. In comparison with 

 the first edition, the present (seventh) edition has one-third more pages of 

 text and about as large proportion of new illustrations. There is hardly a 

 page of the whole book that has not been changed, and probably three- 

 fourths of the book has been reset since it was first issued. This constant 

 revising and improving is in keeping with Mr. King's plan of making each 

 successive edition practically a new book of Boston as it is at the time of 

 publication. The new edition, just from the press, contains upward of 400 

 octavo pages with over 200 engravings, and is handsomely printed and 

 prettily bound. It is probably the largest and most successful book of its 

 class made for any city in America, and is certainly the finest book ever 

 offered for its popular price of one dollar.
