discussion is useless. According to him, we know (from his 
investigation) all about these implements, all about the man 
who made them, the race to which he belonged, his use of tools, 
his machinery and mode of manufacture, his transportation, 
and a large suggestion concerning his culture. If his con- 
clusion be correct, then Mr. Holmes has determined the entire 
history of this man as well as that of the implements them- 
selves. His statement is no longer a theory, it is a demon- 
strated proposition, a proved problem, the work is finished 
and the book is sealed. It is submitted that this is a greivous 
mistake.

1 do not attempt any argument to account for this quarry 
or to explain either the manufacture or use of its implements. 
It is not my discovery, and I am in no wise bound to sustain 
or uphold it. 
In the discussion, I have said no word about Paleolithic 
man in America. That question is not involved here. I have 
elsewhere set forth my opinion on that subject, and I may en- 
large upon it on some other occasion, but not here or now. 
I have sought only to criticise the theories of Mr. Holmes 
in reference to the quarry and its implements, and to show 
what I deem to be the errors in his conclusions, and in doing 
so I have avoided personalities. I have indulged in no 
maligning or abusive words, have conceded to him the most . 
honorable intentions, and a truthful rendering of all his 
facts; and professing for him the kindest and most friendly 
feeling, I assert that in what I have said, I have given my 
own fair, and, as far as possible, unbiased opinion and judg- 
ment, being moved thereto solely in the interest of truth and 
science.
