to arrest the migrations of the reindeer, and deter- 

 mine them to certain points where a deer battue on 

 an extensive scale might give them a supply of food 

 for months. One such erection he traced for forty 

 miles across the country. It appeared to be intended 

 to force the herds of deer towards a lake, and oblige 

 them to take to the water, where they could be easily 

 killed by the natives in their canoes. Similar plans 

 were used by the Indians on the great Canadian lakes, 

 though it does not appear that they executed so great 

 public works to contribute to this end as the Red 

 Indians. I may add, that in the Hudson's Bay dis- 

 tricts, immense numbers of cariboo are killed in the 

 spring when crossing certain rivers, where they are 

 waylaid by the natives. Such facts serve to explain 

 some of the deposits of bones of the reindeer found in 

 France. When, by such means as those above men- 

 tioned, a tribe had succeeded in killing several hun- 

 dreds or thousands of deer, there would not only be a 

 great feast and much cracking of marrowbones, but a 

 long time would be occupied in drying and preparing 

 the flesh and skins, and working the antlers up into 

 implements. In these processes multitudes of flint 

 knives and scrapers would be used, and when the 

 tribe left the place, a deposit of remains of the rein- 

 deer period would be left. This might recur year 

 after year at the same place, till the tribe might be 

 driven from the country by some enemy, or till the 

 deer became exterminated, or were obliged to migrate 

 in some other direction. At other seasons of the year
