72 FLORIDA GEOLOGICAL SURVEY-NINTH ANNUAL REPORT. 
the American Journal of Science, July, 1916, and in the Eighth Annual Report 
of the Florida Geological Survey, plate 17, figure 1, and is included herewith. 
The two bones, left ulna and left radius, it may be noted, are separated by a 
space of five feet. The part of the radius preserved has a length of 145 mm., 
and hence the distance between the bones, as well as the thickness of the section, 
may be readily computed from the photograph. Vertically above the radius, as 
may be seen in the photograph, is twelve or fourteen inches of light colored, 
coarse, clean sand, with which is intimately mixed a quantity of broken marine 
shells, this part of the deposit representing material washed from the underlying 
stratum (No. 1 of the section). This is followed by about ten or twelve inches 
of vegetable material and sand, including, as may be seen in the photograph, 
pieces of driftwood. Above this layer is seen a lens of coarse, clean sand, 
including some pieces of broken marine shells, all of which has been thrown in by 
the stream. This sand lens, as seen in the photograph, has a thickness of 
about six inches. Above this sand lens to the soil line is found fourteen or 
fifteen inches of material consisting chiefly of muck, including some sand, the 
depth of this bone beneath the surface being about forty-two inches. In passing 
to the right the deposit of sand immediately above the radius “pinches out” so 
that the piece of femur which lies approximately four feet farther west is imme¬ 
diately beneath the muck, as is also the ulna. 
In the writer’s description of this locality the depth is given as four feet, 
which is not in excess of the thickness of the deposit overlying some of the 
bones. All of the bones lie at the contact line of this deposit and the next 
older bed, and the varying depth of the bones beneath the surface is due to the 
fact that the top surface of the next older deposit is irregular. The essential 
point involved, however, is not as to the depth at which the bones lie, but the 
fact that the deposits above the bones consist of alternating layers or strata 
which have not been disturbed. A sample was retained showing the sand in 
which the radius was imbedded, and also a sample of the sand including the 
broken shell vertically above the radius. This clean-washed, coarse sand, 
together with the shell fragments, contrasting decidedly with the overlying 
accumulation of driftwood and muck, affords positive evidence of stream-washed 
material, and conclusive proof that the deposit has not been dug into or other¬ 
wise disturbed. 
The illustrations which accompany this paper include: A ground plan of the 
human bones found in place in the canal bank west of the lateral inlet, a photo¬ 
graph showing the ulna, femur and radius, all of which bones are broken and 
incomplete, in place in the bank (omitted from this reprint) ; a closer view 
showing the succession of strata directly above the radius; a detailed view of 
the radius in place, including the sand and shell deposit immediately above it; 
and a view (taken in the laboratory) showing the sand and broken marine shell, 
slightly enlarged, from immediately above the radius. These illustrations afford 
a record that is, it would seem, conclusive as to the conditions under which these 
bones were found. From the photographs it may be seen that flat objects, such 
as shells and shell fragments, lie prevailingly in a single plane of deposition, and 
that the deposits are cross-bedded, both of which features are characteristic of 
deposition by water. A study of the photographs and more especially of the 
section itself shows conclusively that these bones were washed to the place where
