136 The American Geologist. September, 1902 
miles northwest from Kansas City. His sons, Michael T. and 
Joseph F. Concannon, found the skull and most of the bones 
in their digging- near the end of the tunnel, 69 to 71 feet 
from its entrance, 2 to 6 feet from its east side, and 13/2 to 
2 feet above its floor. The bones were disjointed, and were 
l^artly broken, decayed, and irregularly strown about; but 
mainly they were huddled together in one place. The ribs 
and vertebrae were mostly decayed, so that they could not be 
preserved. Half of the broken lower jaw had been previously 
discovered, ten feet nearer the entrance and about one foot 
lower, that is, only a foot above the floor of the tunnel ; and 
near that spot a phalangeal bone was found embedded in the 
wall of the tunnel by one of our party. The other half of the 
lower jaw, matching that found before, was with the chief 
pa,rts of the skeleton. Xo bones besides these of a single 
human skeleton were found in the entire excavation of the 
tunnel ; nor were any implements, artificially chipped stone 
flakes, or other articles of human workmanship discovered.

Mr. Concannon and his sons supplied lights for our exam- 
ination of the section displayed in the tunnel; and they kindly 
showed us where the bones were encountered, with detailed 
relation of the circumstances od" their discovery. At first they 
had not suspected its scientific importance, and nearly a month 
passed before the first newspaper mention of it appeared in 
the Kansas City Star. Within a few days later the locality 
was examined by 31. C. Long and Edwin Butts, of Kansas 
City, Mo., the former being curator of the City Public Mu- 
seum, and the latter civil engineer of the Aletropolitan Street 
Railway, by whom the skeleton was obtained with the design 
of placing it in that museum. The skull was found entire, 
but had afterward been accidentally broken into many pieces, 
which Mr. Long fitted together, depositing it in the museum ; 
but the other bones, including both parts of the lower jaw, 
were at the time of our visit in the possession of Mr. Butts, at 
whose home they were examined by all our party. From where 
the skeleton was found, the overlying loess deposit has a 
thickness of 20 feet, as determined by ]\Ir. Butts, to the surface 
of the ground above. ]^Ieasurements of the tunnel were also
