42 Indian Mownh and SkvU>< in Michigan. 



Mounrls Nos. 4, 5, etc— ^lound No. 4 is eight hundred feet north- 

 east of Mound No. 3. It is three hundred feet long by from thirty to 

 fifty feet wide, and is a low, sandy ridge, with a series of nine conical 

 elevations running along its length, and rising two or three feet above 

 its general level, they having a diameter of 'from twenty -five to thirty 



feet. 



Mound No. 5 is fifty feet to the westward of Mound No. 4, and is 

 of a conical shape, forty feet in diameter, and nearly twelve feet above 

 the level of Lake Huron, lieing between three and four feet higher 

 than No. 4. Two other mounds of a smaller size but similiar shape 

 lie to the nortli of it. 



From Nos. 4 and 5 were obtained a few stone implements, frag- 

 ments of bones and pottery, with flint chips and the usual bowlder- 

 hammers, mostly fractured. Our limited time prevented as thorough 

 an investigation of these mounds as their appearance certainly war- 

 rants. I believe the removal of those conical elevations in Mound No. 

 4 would be rewarded with interesting discoveries. 



Other mounds to the northward and westward, belonging to the 

 series, were also examined to the extent of confirming their claims to 

 a like origin with those more thoroughly explored. A mound south 

 of Mound No. 1 (the first investigated) contributed a few stone imple- 

 ments, which are forwarded. The large implement apjjcars to me to 

 resemble a spade, but may have been designed for some other use than 

 that apparently indicated. 



In conclusion, I would say that the facts observed fully prove tliis 

 extensive group of mounds a rich field for more exhaustive research. 

 And here I repeat the interesting fact, that all the tibise unearthed 

 invariably exhibited the compression or flattening characterizing 

 platycnemic men. Unfortunately the bones generally crumbling to 

 pieces prevented satisfactory measurements. But suflicient evidence 

 was obtained (in connection with my discoveries in other parts of 

 I^Iicliigan) to establish the point, that this race, from the Detroit 

 river to the St. Clair and Lake Huron, was marked with platycncmism 

 to an extreme hitherto unobserved in any other part of this country, 

 or perhaps any other country in the world. I can not but believe, 

 from what I have seen, that future investigation will extend the area 

 in which this type of bone is predominant to the entire region of the 

 Great Lakes, if not of the Groat AVest ; or, in other words, that at 

 least our northern " mound-builders" will be found to have possessed 

 this trait in the degree and to the extent denoted. I am unable to say 

 whether this peculiarity prevails in our modern Indian or not. 



With the exception of the rude stone hammers, and the sinkers, the
