EXPLANATION OF PLATE LXXV. 



Fig. 1. Scraper. Of walrus ivory. The specimen lies flat, touching a horizontal 

 surface all around its underside. The last two specimens, on the con- 

 trary, touch only at the front and rear. Thumb groove a deep furrow, 

 almost concealing the digit. Finger grooves two slight cup cuttings for 

 the tips. Undercut not extending all the way across, so that the lower 

 margin under the thumb touches the ground all the way from front to 

 real-. 



Cat. No. 89316, U. S. N. M. Eskimo of Point Barrow, Alaska. Collected by Capt. P. 

 H. Ray. U. S. Army. 



Fig. 2. Scraper. Handle of wood. Flat bottomed. The material is so much cut 



away that the thumb pocket, the upper and the side finger pockets all 



communicate, and the thumb groove at the end opens into the blade 



socket.

Fig. 3. Scraper. A clumsy specimen of spruce wood resting upon a flat base, 

 scarcely affected by the undercut. Tbe thumb groove wide and for the 

 first joint a deep pocket. Uppej; finger groove only for the forefinger. 

 For the middle finger there is a separate undercut pocket and for the 

 last two fingers the undercut is deeply pocketed. The front is precipi- 

 tate, 2 inches high; the rear prolonged into a flat tailpiece, broader than 

 the rest of the implement. There are a few specimens of this class made 

 of wood, unique in form, but there are no others with precipitate front.
