the bottom slopes; the long, nearly straight, unuotched adge forms 

 the ledge on which the wick rests. 



From St Lawrence island a number of lamps were obtained, showing 

 considerable variety of form. 



Plate XXVIII, 7, represents a lamp made of clay, 11|; inches long, 0^ 

 wide, and 2| deep; it is siiboval in outline, with a tray-shape bottom; a 

 high, thin ridge runs along each side, just above the bottom, which 

 projects upward, and inclines a little outward; a deej) notch is cut 

 through tlie middle of these ridges close to the level of the bottom for 

 receiving the wick. The form of this lamp is precisely that indicated 

 on the toy carving from the Diomede islands above described (figure 19). 



Plate XXVIII, 8, illustrates a lamp from St Lawrence island, 14i inches 

 long by 12^ wide and 2| deep. It is like the last in general shape, but 

 slopes gradually from the sides downward to within a short distance 

 of the bottom, Avhen it drops suddenly to a depressed area about an 

 inch deep, which occupies the entire bottom of the lamp; along each 

 side of the bottom projects a ridge, which slopes upward and a little 

 toward the middle. These ridges are pierced by a round hole near 

 each end, about on a line with the bottom of the lamp, through which 

 the wicks were inserted. Both this lamp and the one last described 

 undoubtedly stood upon framework supports, and were used probably 

 for cooking i)urposes. 



A tray-shape clay lamp (number 63569) from St Lawrence island is 

 16^ inches long by lOf wide; it has two projecting ridges on the inner 

 sides, midway between the rim and the bottom, for supporting the 

 wick. This, like the other large lamps from this island already 

 described, was undoubtedly used for cooking. 



Plate XXVIII, 4, shows a tray-shape lamp from St Lawrence island, 

 which undoubtedly was used solely for illuminating purposes. It has 

 the upper border Hattened smoothly on three sides; along the front the 

 slope extends gently backward toward the deepest part. Extending 

 lengthwise, midway between the bottom and the front border or lip, is 

 a thin projecting ridge; the front border of the lamp above this ledge 

 shows signs of having been burnt; evidently the wicks had their bases 

 supported against the raised ridge while their upi)er edges projected 

 from the, lip. 



Plate XXVIII, 5, represents the support for the last-described lamp. 

 It is made of clay, and is in the form of a pot 5 inches high and 6f wide. 

 It has a flat bottom, with tlie sides rounded to the front, where a cres- 

 centic depression is made in the border, with a slightly raised point on 

 the rim at each side. The lamp was placed on the mouth of the vessel, 

 the depressed portion of which is just beneath the point where the wick 

 rests along the outer edge of the lip, so that any drippings of oil which 

 might run down would be caught in the vessel below. 



The lamp from St Lawrence island shown in plate xxviii, 9, is some- 

 what similar in shape to the preceding, but having the bottom flattened
