28o THE ANTIQUITY OF MAN 
the pelvic bone belonged to any recent mammifer other 
than man, such a theory would never have been resorted 
to ; but so long as we have only one isolated case, and 
one without the testimony of a geologist who was present 
to behold the bone, while still engaged in the matrix, and 
to extract it with his own hands, it is allowable to suspend 
our judgment as to the high antiquity of the fossil." 
After what we have seen at Trenton, the plea of 
" isolation " cannot anymore be urged. The legitimate 
inference must be drawn, be the loess of the Mississippi 
valley what age it may, that man was living in the 
Mississippi valley during its deposition. 
Further evidence is found in support of this conclusion 
as we journey northwards along the Mississippi, and 
reach those states which were covered by the ice sheet 
at intervals of the Pleistocene period. For our present 
purpose it is more profitable to leave the Mississippi 
and follow its great tributary, the Missouri. At Kansas 
City we reach the "furthest south" of the ice sheet. 
The loess deposits are everywhere abundant, forming 
high terraces or bluffs on either side of the Missouri. 
On the west bank of the river, some distance above 
Kansas City, near Lansing, is the farm of Mr M. 
Concannon. In 1902, Mr Concannon and his sons made 
a tunnel into the terrace of loess, on the side of the 
valley, to serve for the storage of apples and other farm 
produce. At a distance of 70 feet from the entrance of 
the tunnel, and at a depth of over 20 feet below the 
surface of the land, a human skeleton was found. Some- 
what nearer to the entrance a child's jaw and an artificial 
chert chip were obtained. 
There is no doubt as to the authenticity of the 
discovery at Lansing, nor is there any room for difference 
of opinion regarding the kind of man discovered. The 
skull is now in the National Museum, Washington. 
Both skull and skeleton have been examined and 
described by Dr Hrdli(^ka. They are parts of a man of 
medium stature (about 1*65 m.), and about fifty-five years 
of age. " All the parts of the skeleton, and particularly
