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.

The methods used by successful Long Island duck raisers differ widely in some particulars and since in the space at command, it has been impossible to describe all the methods used, the plan has been adopted of detailing in the main the methods of one successful grower. This it is believed will prove to be more helpful and less confusing than to attempt to give the method of several different men.
