600 Vestiges of Glacial Man in Minnesota. [June, 
not for a moment to be believed that such remains would have - 
been thus distributed by aboriginal artificers. It was simply im- 
possible that the quartz-workers should have limited their manip- 
ulations to a strip of sand six or eight feet wide and thirty to 
forty long, less or more, heaping upon this narrow defile thou- 
sands upon thousands of fragments, yet leaving absolutely no 
small splinters nor chips beyond, neither up the slopes of the 
notch nor elsewhere in the vicinity. 
The above-cited peculiarities of distribution remained the puz- 
zle of the situation until certain of the accumulated objects began 
to range themselves under types which, though vaguely outlined 
in touches of extremely rude workmanship, were, nevertheless, 
distinctly palzeolithic in general tone. 
The quartzes were now, for the first time, conjecturally classified 
with the palzolithic implements discovered by Professor Winchell 
imbedded within the surface of the terrace-plain, and figured in 
his geological report of a reconnoissance in Morrison county. It 
was judged that, as had been the case with the Winchell speci- 
mens, these objects had been included, primarily, within an upper 
stratum of the terrace-plain, whence they might easily pee 
washed by the drainage water copiously discharged through po 
notch. Such pieces, it was argued, would naturally be a al
