from the States of Massachusetts, Connecticut, New York, Pennsyl- 

 vania, Ohio, Indiana, Kentucky, Illinois, Iowa, Louisiana, Michigan, 

 and Wisconsin, and a specimen has been found in Missouri. The 

 native home of this stone is along the Atlantic Coast, from Rhode 

 Island to Canada. It is also found on Lake Lake Superior and 

 Green Bay. It does not occur in situ, in Ohio, where objects made 

 of it are more abundant than in any other part of the United States, 

 but water worn pebbles, some of them sufficiently large to form the 

 objects found, are plentiful. 



Obsidian was another article in which the prehistoric merchant 

 dealt. The Geological Survey of the Unitea States Government has 

 ascertained that this mineral is found in Washington, Oregon, Cali- 

 fornia, Idaho, Montana, Wyoming, and New Mexico. Extensive 

 deposits have been found in the Yellowstone National Park. 



Messrs. Squier and Davis have found articles of obsidian, mostly 

 arrow heads, spears and cutting implements in five mounds of the 

 Scioto Valley, in Ohio. Specimens have also been found in 

 Tennessee. 



Where did they get this obsidian ? The Aztecs used it exten- 

 sively, and it is probable the inhabitants of Ohio received their 

 supply from that point. If so, they must have carried it a straight 

 distance of over 1700 English miles, if however, they were better 

 geologists or miners than we generally assume them to have been, 

 they may probably have found their supply in the Yellowstone 

 region. In that case the distance from Ohio would be over 1300 

 English miles. 



From these evidences it will be seen that the stone folks of both 

 continents had a sort of ill-defined commercial relation amongst the 

 various tribes. Of the Palgeolithic man of Europe, little can be 

 said regarding his mode of exchange. Although the tribes were 

 widely scattered, the physical characteristics of the men of the time 

 were such that no doubt they often came in contact for the pur- 

 poses of barter, or met in the chase or at war with each other. In 

 any of these cases it is likely there was more or less exchanging of 

 articles, while in the case of war the stronger would appropriate 

 whatever he fancied or imagined he had any use for from amongst 

 the property of his opponent, and in this way, no doubt, many of
