Luther Gulick, M.D. ("History of Physical Training"), International Y. M. C. A. Training-School: "Your letter of the 7th is at hand, with the excellent cuts that were inclosed. You ought not to charge less than one dollar for the book. I do not know but what you could get more. I shall be very glad to purchase a copy of the book as soon as it is published. Please let me know."
G. W. Ehler, Physical Director of the Y. M. C. A. of Chicago, Central Department: "There is a necessity for a good book on tumbling, as there is none now in print to my knowledge; and I believe that such a book would meet with a very hearty reception by physical directors and by others who are interested."
Robert J. Roberts: "I approve of your idea of getting out such a book as you speak of. I would keep out the dangerous exercises; or, if you put them in, hedge them in so that amateurs will not use them. There is no kind of physical work thut will so harmoniously develop every part of the body as tumbling."
