84 EXPLORATION OF BURTON MOUND [BrH. ANN. 44 
Dish of cream-colored limestone, 174.6 mm. long, 153.9 mm. wide, 82.5 mm. 
thick. Edges and bottom rounded. Coneavity 88.9 mm. diameter, 26.9 mm. 
deep. The specimen was found as two halves. 
Dish of cream-colored limestone, 146 mm. diameter, 69.8 mm. thick. Edges 
rounded. The concavity is 76.2 mm. diameter, 47.6 mm. deep. The concavity 
shows pecking and has in it three serpula holes from the rock, which was 
evidently picked up on the beach. 
Dish of cream-colored limestone. Very light in weight. The edges contain 
serpula holes. 2381.7 mm, long, 225.4 mm. wide, 104.7 mm. thick. Edges rounded, 
bottom flattish. The concavity measures 123.8 mm, diameter, 30.1 mm. deep. 
This is the largest of the dishes of soft limestone. 
TRAY OF SANDSTONE 
Only one specimen was obtained of the typical flat sandstone tray 
or platter, but this is a large-sized and important one. 
Tray of somewhat buff colored grayish sandstone with a very high sand 
content, 434.9 mm. long, 288.9 mm. wide, 44.4 mm. high. The edges are rounded. 
The deepest part of the concavity is 19 mm. diameter, the center of the con- 
cavity being shallower, measuring only 4.7 mm, lower than the edge of the tray, 
The concavity starts about 38.1 mm. from the extreme edge. The bottom shows 
no pecking and is quite flat. (Pl. 9, d.) 
OLLAS OR COOKING POTS OF STEATITE 
Fifteen steatite ollas or cooking pots in entire condition or nearly so 
were obtained, as well as quantities of fragments that would not piece 
together. Ollas of gray steatite are said to have been obtained by 
barter from the Catalina Island Indians, who lived, roughly, 100 
miles away, and the larger ollas were considered very valuable even 
at the source of supply. Several of the ollas taken are among the 
largest and most symmetrical ever obtained in southern California. 
The largest specimen stands 1554 inches high and weighs 72 pounds. 
The specimens vary considerably as regards relative size of the 
mouth or orifice. Some are almost bowls in shape and may have 
been used both as cooking pots and as receptacles. 
A zigzag incision decorates the rim of several of the specimens. 
Olla of gray steatite, 311.1 mm. diameter, 165.1 mm. high, orifice 157.1 mm. 
diameter, rim squared and varying in width from 12.7 mm. to 174 mm. The 
rim is undecorated. The concavity is 168.2 mm. deep. The bottom is rounded, 
its flatter portion measuring about 177.8 mm. diameter. 
Olla of black steatite, beautifully made and exhibiting minute crinkly vein- 
ings and blotchings of a dark gray color on its surface; 155.5 mm. diameter, 
95.2 mm. high, orifice 111.1 mm. diameter. Rim squared and 7.1 mm. diameter. 
A groove runs around 3.1 mm. to 4.7 mm. below the rim. Concavity 87.38 mm. 
diameter. The bottom is flattish at its central portion. Surfaces highly pol- 
ished. Such a vessel could be used either as an olla or as a bowl. The clean 
condition of the present specimen suggests that it had not been used for cooking. 
Olla of gray steatite, 130.1 mm. diameter, 101.6 mm. high, orifice 92 mm. dia- 
meter. Rim merely rounded. Concavity 92 mm, diameter. Bottom somewhat 
flat for a space about 88.9 mm. diameter.
