tree started. It is my judgment that not less than five hundred 
years have elapsed since these stones were covered by sedimen- 
tation, and I should think the time would not exceed one thou- 
sand. 
As stone axes, knives and arrow-heads were searched for 
among these stones and not found, I think they were not used by 
the people who used the stones for cooking. Among so many 
stones of that kind, and in a camp, some tool would have been 
dropped. Such tools are found on the present surface in every 
neighborhood about here. If this should prove correct (that none 
were used by this people), it would prove that the stone axe is 
not so old as we have heretofore thought it to be. Or, did these 
people take extra care of their tools? Then why did the much 
later Indians having equal use for heir tools, drop them all over 
the country ? Or, were these suddenly abandoned on the intro- 
duction of steel tomahawks, knives and fire arms ? 
There are no Indian mounds within fifty miles of this camp. 
It was, therefore, hardly the work of the mound-builders. My 
ancestors for three generations were pioneers, and well acquainted 
with Indian character and customs from 1760 to 1820, and from 
Massachusetts to the Wabash, and while I have heard very many 
of their Indian stories I have never heard of their seeing any- 
thing like what I have described, nor do I remember to have 
seen it described in any account I ever read. Is this a new fea- 
ture of an ancient subject? or am I illy informed on it?

The session of the American Association for the Advance- 
ment of Science for 1885 has just adjourned its session at Ann 
Arbor, Michigan. The meeting presented many admirable fea- 
_ tures. Other things being equal, a university town has superior 
advantages for the conduct of scientific gatherings. The spirit of 
_ the place is congenial. Facilities for presentation and illustra- 
. = are at hand. The university buildings furnish excellent 
_ assembly roonis. The social conditions are appropriate and not 
stracting. Such were the circumstances which attended the 
e Ene and the members experienced their benefits to the
