shoulder one night by a secret service agent and told to leave the next morning for the United States.
So it is in Mexico. Zimmermann is not alone in his intrigues.
With the sincere hope that this book will help Americans to understand Mexico as it is I submit it to the reading public. Everything, including future peace between the two nations, Mexico and the United States, and their mutual prosperity, depends upon our having a full understanding of the situation. This book does not pretend to contain all there is to be known about Mexico to-day but the author believes it to present a true account of conditions and politics in Mexico at the time of its writing.
I have employed in this book the major portion of five articles written for The Saturday Evening Post to which I have added considerable new material. I am indebted to so many Americans and Mexicans for assistance and information, some whose names might be mentioned, others whose names cannot be given, that I welcome this opportunity to thank them all.
