Canvas-back duck.—This is peculiarly a delicacy belonging to the United States, can be tasted in perfection nowhere else, and is a somewhat costly dainty even there. A very good imitation, however, can be made by the curious in the matter of novelty if they stuff a plump British wild duck with celery before roasting, as this gives the flesh some measure of the celery flavour which is the speciality of the canvas-back, and is gained by the birds feeding on the wild celery found in the marshes of America.
