76 EXPLORATION OF BURTON MOUND (ETH. ANN, 44 
Entire mortar of gray sandstone containing large pebbles of conglomerate 
material and small white shells, 374.6 mm. long, 336.5 mm. wide, 127 mm. tall. 
Rim flat and broad. The concavity is 196.8 mm. diameter and 95.2 mm. deep. 
The hole in the bottom is only 34.9 mm, diameter and the bottom is 31.7 mm. 
thick. The fracture suggests that the hole was broken from the inside, prob- 
ably in the course of use. The edges are old fractures, worn smooth. The 
bottom is flat and rough. (PI. 5, ec.) 
Entire mortar of very coarse sandstone of yellow ochre color. The stone 
contains coarse gravel; 200 mm, diameter, 79.3 mm. high. Rim rounded and 
shows in its present condition no trace of asphalt, although the specimen is 
surely a hopper mortar. The concavity is 26.9 mm. diameter. Edges rounded. 
The entire bottom is rounding. (PI. 7, f.) 
Entire mortar of brownish gray sandstone, rather coarse and friable; 184.1 
mm. diameter, 98.4 mm. high. The rim is rounded, but shows in its present 
condition no trace of asphalt, although the specimen is surely a hopper mortar. 
The edges are rounded, as is also the bottom. There is one large chip broken 
off the edge. 
Entire mortar of brownish gray, very coarse and friable sandstone. This 
mortar is almost spherical in shape, 239.7 mm. diameter, 155.5 mm. high. The 
rim is rounded and shows no trace of asphalt. The concavity is 133.3 mm. 
diameter and 47.6 mm. deep. The sides and bottom are rounded, apparently 
without pecking. (PI. 4, ec.) 
Entire mortar consisting of a beach bowlder full of serpula borings. 234.9 
mm. diameter, 123.8 mm. high. The concavity is 76.2 mm. deep. (Pl. 4, d.) 
Fragment of a metate of greenish gray sandstone, rather coarse; 612.7 mm. 
long, fragment 196.8 mm. wide, 95.2 mm. high. Rim rounded. Concavity 47.6 
mm. diameter. One side of the metate is missing. 
Fragment of bowl of brownish gray sandstone which is much disintergrated 
and appears to have been through fire. The fragment is 234.9 mm. long, 
180.9 mm. wide; 177.8 mm. of rounding rim are intact. The other edges 
consists of old fractures. The bowl had an original height of 177.8 mm. A 
little of the old bottom is intact and is 44.4 mm. thick. 
Entire metate of gray sandstone, somewhat triangular in shape; 479.4 mm. 
long, 336.5 mm. wide, 177.8 mm. high. The rim is somewhat flat. The 
concavity is 330.2 mm. diameter and 79.3 mm. deep. The outer edges are 
irregular, the bottom flat. Donated by Mrs. West-Bates. Obtained from Bur- 
ton Mound in 1901. (PI. 6, ¢.) 
Entire metate of gray sandstone, somewhat oblong in shape. 485.7 mm. long, 
336.5 mm. wide, 177.8 mm. high. Rim rounded. Concavity 122.2 mm. diameter. 
A hole broken in the bottom measures 88.9 mm. by 49.2 mm. Outer edges 
rounded, bottom flat. Donated by Mrs. West-Bates. Obtained from Burton 
Mound in 1901. (Pl. 6, e.) 
Entire bowl of gray sandstone, round in shape ; 393.7 mm. diameter, 180.9 mm. 
high. The rim is rounded, forming a sharp curve where the concavity begins. 
The coneavity is 222.2 mm. diameter and 88.9 mm. deep. The outer edge 
is neatly rounded, as is the bottom. Donated by Mrs.’ West-Bates. Obtained 
from Burton Mound in 1901. (PI. 5, a.) 
Entire bowl of greenish gray sandstone, hard and fine textured; 209.5 mm. 
diameter, 158.7 mm. high. The rim is rounded but is quite rough and irregular 
in shape in its present condition. The concavity is 120.6 mm. deep. The bottom 
is neatly rounded with a natural depression 57.1 mm. diameter at one side. 
Purchased from Mr. José Ortega, who obtained it from the Burton Mound in 
1901.
