Spadona

An assorted case may contain fifty bundles of white feathers—some only of which will be perfectly long, full-tipped specimens—and perhaps 200 bundles of the qualities and shades known as Femina, Byocks, Spadona, Boos, and drab, together with the beautifully rich and silky black.

To conclude, then, it is considered by those who have carefully studied the subject, that the western portion of this continent presents certain advantages in ostrich culture which Southern Africa does not possess, and it is believed that the time will come, when ostrich feathers, running through all the varieties of Femina, Boos, Byock, and Spadona, as the grades are called, will be one of the features of the California market.

The usual kinds of ostrich feathers known to the trade come into the Tripoli market. These are whites, blacks, feminas, byocks, spadonas, boos, drabs and floss.
