mounds on Gideon's farm, Minnesota. 



427 



feet in diameter, with the entrance also protected, but' it was almost 

 useless for defense, as it was commanded by a bill-top about GOO feet 

 distant, and 49 or 50 feet above it. On the other side was a belt of 

 timber about a rifle-shot away. Within the enclosure was found a hu- 

 man skull with a metal arrow-head embedded in it, thus hinting at the 

 fate of its builders. I give a rough sketch of the locality. 



Around Lake Minnetonka arrow-heads and other implements are 

 sometimes found. I was shown a stone hammer this 

 summer, but was uuable to obtain it. It was made of 

 an egg-shaped quartzose pebble, was 4^- inches long, 

 3^ in diameter, and would weigh about four pounds. 

 It had a deep groove around it, probably to bind it to 

 its handle. 



I also examined the skull, probably Ox an Indian, 

 which was found while excavating for a street in the 

 city of Minneapolis. There were three or four bodies f rom Lake Minne- 

 close together, which had evidently been buried for a tonka, 

 long time. The appearance of the teeth showed it to be that of a per- 

 son in the prime of life. It measured in circumference 21 inches, and 

 from ear to ear, over the top of the head 12£ inches.
