viii PREFACE TO THE AMERICAN EDITION
extended scientific collaboration in the near future, and are embodied in two new chapters written for the American edition. I know that my method has been widely spoken of in America, thanks to Mr. S. S. McClure, who has presented it through the pages of his well-known magazine. Indeed, many Americans have already come to Rome for the purpose of observing personally the practical application of the method in my little schools. If, encouraged by this movement, I may express a hope for the future, it is that my work in Rome shall become the centre of an efficient and helpful collaboration.
To the Harvard professors who have made my work known in America and to McClure*s Magazine, a mere acknowledgment of what I owe them is a barren response; but it is my hope that the method itself, in its effect upon the children of America, may prove an adequate expression of my gratitude.
