This book was published in 1936 by the Bruce Publishing Company, Milwaukee, U.S.A. As far as can be traced, the 1936 edition has no copyright notice, although the 1939 revised edition has.
Books published in the U.S.A. between 1923 and 1964 require a copyright notice to claim copyright, otherwise they are in the public domain. If they do have a copyright notice included, copyright needs to be renewed after 28 years.
Consequently, the first edition should have had its copyright renewed in 1964 (if it had had a copyright notice) and the revised edition in 1967. The U.S. copyright office renewal records do not show a renewal for these editions in either 1964, 1965, 1967 and 1968. This book is therefore out of copyright in the U.S.A.

This book is therefore also in the public domain in The Netherlands.
