curbing, were all on edge. This curbing had its northern and west- 
ern sides injured in the early excavation, but the other sides remain 
whole, and were removed from their position and laid on the surface 
of the lawn without breakage. The nails used in the construction of 
this curbing were partly of the wire variety, and partly old-fashioned 
square nails. 
Below the curbing the shaft of the well is round and averages some 
46 inches in diameter. We excavated this shaft to a depth of 101% 
feet, but were forced to cease operations because of the entering of 
water, which in a day or two had filled the bottom of the hole to a 
depth of 3 feet. It is remarkable that the water rose to so high a level 
at this elevated position on the mound, and the watering of the sur- 
rounding lawn evidently contributes only partially to this flow, if at 
all. The water was perfectly good and sweet and was free from any 
taste or odor resembling sulphur. The well is only about 200 feet 
from the sulphur springs and apparently is supplied with water from 
the same formation. 
DESCRIPTION OF THE ARTIFACTS 
The objects taken from the mound have, at the suggestion of Mr. 
George G. Heye, been classified according to the material of which 
they are made, thus conforming with the presentation in his recent 
paper on the San Miguel Island expedition of the Museum of the 
American Indian."® 
Generally speaking, the artifacts had the appearance of being old 
and long subjected to the havoc of soil and water. Their long history 
in the ground had been climaxed in more recent times in several of 
the areas by lying under a well-watered lawn or garden for a period 
of 20 years. And many of them had patently been broken or dam- 
aged before being placed in the graves. We saved everything that 
was taken from the excavation and time and ingenuity has been used 
in piecing some of the broken objects together. 
Stone, shell, bone, and wood have in this mound resisted the chem- 
ical action of the soil with success, decreasing in the order in which 
they are named. It was not uncommon to find shell beads reduced 
to chalky softness, and even sandstone fragments were met with in 
disintegrated condition.

Flat-rimmed bowls of sandstone with comparatively thin and even 
walls and flat or somewhat flattish bottom form a definite type. The
