46 THE CONDOR VoL. X The ruggedness of this coast is occasioned apparently by a great fault, or crack in the earth's crust, running roughly north and south. The sea-floor having been dropped to westward, the upturned edges are left on shore at the mercy of the waves. Moreover, the shore line is complicated by transverse folds of rock, the precursors of the Olympic Mountains to the eastward; and these are usually marked, off-shore, by a chain of islets in descending series, the outermost member of the series being the most denuded, and the innermost being mere detached fragments of the mainland with forest crowns intact. It is thus that the more than six score of islets, which rise above the spray-line, are grouped into nine principal systems, roughly corresponding to the chief promontories. Because of their proximity, considered as a whole, to the Olympic Mountains, and because they are in a sense the by-products of the sanhe orogenetic movement, I have proposed for these islands the nanhe Olympiades (pronounced Olympiah-diz). The nanhe will be all the more convenient now that they are arbitrarily divided into three administrative groups.- All the islands between Oray's Harbor and the Straits of Juan de Fuca are coy- A WHITE-CRESTED CORMORANT ROOKERY; ?UILLAYUTE NEEDLES RESERVATION Photo by W. Leon Dawson ered by the executive orders, save Destruction and Tatoosh, which are already oc- cupied by Government lighthouses, and upon which, presumably, the sanhe meas- ure of protection will be enforced by the Lighthouse Board. James Island, altho specified in the orders, is virtually a part of the mainland, and is already occupied for gardening purposes by the Quileute Indians. With these exceptions, none of the Olympiades has any economic value, save that of bird propagation or as a lounging place for sea-lions. Those islets which are not fully denuded by the combined action of the ele- ments and the sea-birds, are covered with a dense growth of bushes, chiefly a dwarfed salmon berry and salal. This crown invariably affords cover for the Rusty Song Sparrow (_A/felos?iza cnerea morphna) and occasionally for the Sooty Fox Sparrow (Passerella iliaca fuliginosa).
