This publication by Harry M. Lamon and Rob R. Slocum, both Poultrymen at the Bureau of Animal Industry at the United States Department of Agriculture, was originally published in 1922. It contains numerous photographs of various breeds of ducks and geese and is intended to give an insight into the workings of the poultry industry. Included in this work is also a brand new introduction on the history and methods of poultry farming. The following passage is an extract from the book's preface:'Of all lines of poultry keeping, duck raising is unique in that it lends itself to the greatest degree of specialization and intensification along lines which are purely commercial. On a comparatively small area thousands of ducklings can be reared and marketed yearly. The call for information concerning the methods used by these commercial duck raisers has been considerable, and since such information is not available in complete concise form the present book has been prepared partly to furnish just this information.'
