Jack Kruschen makes his third and final Bonanza appearance as Giorgio Rossi, the bombastic patriarch of an Italian wine-growing family. Having been awarded a parcel of Ponderosa land to create a vineyard, Rossi causes consternation for Ben Cartwright when he invites a group of hungry Indians to pay a visit. What Ben knows, but Giorgio doesn't, is that once they've encamped on the Rossi property, the Indians will assume they've been invited to stay on permament. Also making return visits to the series are Penny Santon and Brioni Farrell as Giorgio's wife Maria and daughter Regina. Fans will be amused by the layout of the Rossi living room, which is an exact replica of the Cartwrights' (as well it should be, inasmuch as the same set was used!) Written by William F. Leicester, "The Sound of Drums" first aired on November 17, 1968.
