Profits in poultry : useful and ornamental breeds and their profitable management . Fig. 88(a),—ROUEN (iai) Fig. 88(6).—AYLESBUBY DUC26. UAISIXG DLCKS. 233 rapidly and fattens easily. Tin- common tame duck issupposed to have descended from the wild Mallard duck,A7ias boshas, conmion to this country and Europe. Itbreeds freely with this species, and also with severalother species of wild duck ; in some cases the progenyis capable of reproduction of its kind, in others mule-birds or ** mongrels^ result. The fact that a very dif-ferent class of birds is produced where the Mallards arecrossed with other species and where the common duckis so crossed, with other ])oints of difference, throwssome doubt on the assertion that the Mallard is theparent of our common ducks. Besides, efforts to domes-ticate the Mallard have not been successful as a generalthing. We have, however, many wild ducks capable ofdomestication, and. the exj)eriment ought to be welltried with all, for thus our stock of domestic poultrymay be essentially increased and improved. The Rouen breed is the most highly esteemed
