40 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



IS owned by the Sauta Cruz Island Wool Growing Company. Near a 

 good wharf at Prisoner Harbor stands a substantial adobe building, and 

 back of it extends a beautiful valley, about 8 miles in length, which 

 afforded us, near its mouth and on the banks of a running stream under 

 old oaks, an excellent camping-ground. 



Our party spent about one mouth, from May 10 to June 12, on this 

 island, during which time we made explorations all along its shores 

 65 miles in extent. Here we found the United States Coast Sur- 

 vey steamer Hassler, Captain Taylor, engaged in making soundings 

 round the island; and as the Superintendent of the United States Coast 

 Survey, Capt. C. P. Patterson, in view of the fact that the expedition 

 was made at the expense of the Government, gave permission for the 

 transport of our party to such places as lay in the route of sailing of 

 the courteous and obliging Hassler party, it gave us a great advantage 

 in prosecuting our work, and saved much expense in sparing the neces- 

 sity of chartering a vessel or hiring jDack-animals. 



Our main attention was again directed to the finding and examining 

 of graves. From our camp at Prisoner Harbor we made trips to differ- 

 ent places on the island, taking only the necessary provisions, water, and 

 blankets along with us. We also carried some boxes in shooks, in 

 which temporarily to pack our finds. 



Our first station was at Tinker's Cove (Map 4) [Plate 12], a narrow 

 fiord-like shelter for small craft only, with high walls on both sides that 

 seem to exclude all possibility of a farther advance. Proceeding from 

 our temporary camp among the rocks near the sand beach of Tinker's 

 Cove, we climbed the western face of the gorge, and approached the shell 

 deposits first observed while passing on our way from San Miguel Island 

 to Prisoner Harbor. We found the kjokkenmoddings located on a 

 plane about 50 feet above the sea, which is arrested a little ways from 

 shore by a steep ascent with rocky outcroijpings. The ground is rocky^ 

 and terminates at the beach in an apron of horizontal stratification, 

 washed by the ocean, and, at low water, quantities of eatable mollusks 

 can be gathered. Two hundred yards to the westward, on the bight of 

 a shelter similar to Tinker's Cove, but with an inferior landing, is a 

 small spring supplying drinkable water. Great masses of kelp exist in 

 the adjoining inlet and among the outlying rocks (of which but one ap- 

 pears on the map), where we may watch the motions of a great number 

 of seals and sea-lions in catching fish, very abundant in these waters. 

 One of the two buryinggrounds discovered here was still well marked 

 with whale-bones above the ground, probably not so conspicuous as 

 shown in the sketch (A) [Plate 21] for the sake of illustration. Both 

 were in the deposits of the accumulated kitchen -refuse, as the sur- 

 rounding bottom below its shallow subsoil was impenetrable for the 

 tools of these people. In the arrangement of the graves, nothing was 

 observed that materially differed from those on San Miguel. We only 

 found here more wood in the walling-up of the graves and more char-
