8 H. Gillman—Indian Mounds in Michigan. 
tent of Mound No. 3, as also in a mound sixty feet to the west 
of it, contributed nothing specially entitled to record. 
Mounds Nos. 4, 5, ete.—Mound No. 4 is eight punanes: feet 
northeast of Mound No. 3. Itis three hundred feet lon 
from thirty to fifty feet wide, and is a low sandy ridge ar a 
series of nine conical elevations running along its length, and 
rising two or three feet above its general ‘Sid they having a 
diameter of from twenty-five to thirt 
Mound No. 5 is fifty feet to the Pe ga of Mound No. 4, 
and is of a conical shape, forty feet in diameter, and nearly 
twelve feet above the level of Lake Huron, being be between three 
and four feet higher than No. 4. Two ‘other mounds of a 
smaller size but similar shape lie to the north of it. 
rom Nos. 4 and 5 were obtained a few stone implements, 
fragments of bones and pottery, with flint chips and the usual 
_ boulder-hammers, mostly fractured. Our limited time pre- 
vented as thorey an investigation of these mounds as tho 
appearance inly warrants. I believe the removal of those 
conical elevations in Mound No. 4 would be rewarded with in- 
seer ¢ discov 
eee re 5 the northward and westward. belonging to 
the ae were also examined to the extent of confirming 
their claims to a like origin with those ve thoroughly ex- 
ored. A mound south of Mound No. | (the first investigated) 
contributed a few stone implements, which are forwarded. The 
large implement appears 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 
this extensive group of mounds a rich field for more exhaustive 
research. And here I repeat the interesting fact that all the 
tibie unearthed invariably exhibited the compression or flatten- 
ing characterizing platyenemie men, Unfortunately the bones 
generally crumbling to pieces prevented satisfactory measure- 
ments, But sufficient evidence was obtained (in connection 
with my discoveries in other parts of Michigan) to establish the 
i that this race, from the Detroit River to the St. Clair and 
ke Huron, was marked with platyenemism to an rs 
hitherto unobserved in any other part of this country, or : 
haps any other country in the world. I cannot but AER S 
from what I have seen, that future investigation will extend the 
area in which this type of bone is predominant to he antes 
ion of the Great Lakes, if not of the Great Wes or, 
other words, that at least our northern ‘“ calcd baie? ‘vill 
be found to have this trait in the degree and to the 
extent denoted. Iam unable to say whether this peculiarity 
prevails in our modern Indian or not,
