Philadelphia Telegraph:—"In this book Mr. Spalding has written the most complete and authoritative story of base ball yet published."
New York Herald:—"If there is anyone in the country competent to write a book on base ball it is A.G. Spalding who has been interested in the game from its early beginnings."
I.E. Sanborn, Chicago Tribune:—"'America's National Game' has been added to the Tribune's sporting reference library as an invaluable contribution to the literature of the national pastime."
O.C. Reichard, Chicago Daily News:—"It is cleverly written and presents information and dates of great value to the newspaper man of to-day!"
George C. Rice, Chicago Journal:—"I have read the book through, and take pleasure in stating that it is a complete history of the game from the beginning until the present time."
Sherman R. Duffy, Sporting Editor Chicago Journal:—"It is a most interesting work and one for which there was need. It is the most valuable addition to base ball literature that has yet been put out."
Joseph H. Vila, New York Sun:—"I have read it carefully and with much interest. It is the best piece of base ball literature I have ever seen, and I congratulate you on the work."
Tim Murnane, Sporting Editor Boston Globe:—"You have given to the world a book of inestimable value, a classic in American history; a book that should be highly prized in every home library in the country."
Francis C. Richter, Editor Sporting Life, Philadelphia:—"From a purely literary standpoint, your work is to me amazing. Frankly, I would not change a line, for the reason that the story is told in a way to grip the reader and hold his interest continually."
Los Angeles Times (editorial):—"Spalding's book has been out six months and ninety thousand copies have been sold. We understand there will be other editions. America has taken base ball seriously for at last two generations, and it is time enough that the fad was given an adequate text book."
