HRDLICKA] SKELETAL REMAINS 63 
A closer examination of the land along the shore northward, as 
well as southward, revealed many interesting conditions. Beginning 
with Mr. Webb’s house, it was found that a short distance eastward 
from the spot where the Osprey skull was discovered and near the 
end of the shell mound a small stream of brownish water flows into 
the bay; at the mouth of the stream is a bed of irregular, ferru- 
gimous limonite concretions, mostly connected, but easily detachable. 
The concretions appear to be at about the level of the sand which is 
marked by ferruginous discolorations at the locality of the Osprey 
skull. They rest on a clayey and sandy deposit containing no solid 
rock, probably an ancient bed of the bay. The surface of the con- 
eretions nearest the mound was seen to include some shells of recent 
species, which may have formed part of the great shell heap. In

these concretions, which resemble those in which the Osprey skull 
is held, were found also small pieces of ordinary Indian pottery. 
For a considerable distance east and south of this locality no rock is 
exposed, but about half a mile to the south ferruginous concretions 
and also some washed-out “ phosphate rocks,” consisting of cetacean 
fossils, appear on the beach and in the shore; thence they increase 
southward until near the place of the South Osprey find, where they 
form a substantial part of the shore. They are covered with the eray- 
ish finer conglomerate above described. They extend for an unknown 
distance south of this locality, and wherever they exist the beach is 
lined with pieces of rock, undermined by the waves and broken down 
by their own weight, as well as with remnants of old fossils washed 
out from this rock, A careful and repeated search failed to bring to
