The White Turkey. When both white and black varieties of a bird are found, it is usual to consider the white a sport from the black. While such sports may occur, the history of white vari- eties of fowls shows that they are largely made up of white mongrels which ap- proach the desired type. The white birds derived directly from mixed colors of the same race seem to have come usually from the lightest-col- ored specimens of the parent stock. Hence, in the case of the white turkey it is more reasonable to suppose that the white turkeys were derived by selection from the same general stock as the blacks, than to assume that they came from the latter as sports, especially as no cases of sporting are recorded. The name " White Holland " has been given to the white vari- ety of turkey because the color was common in Holland, but it may safely be asserted that the greater part of the white turkeys in America have been derived by selection from flocks in which gray in various shades was the prevailing color.
