MAN AND THE GLACIAL PERIOD. 621 



study of the same and other objects from that locality has only 

 served to strengthen the opinion I then expressed. 



The quartzes discovered by Miss Babbitt I first saw in the 

 autumn of 1882, when she forwarded a box of them for my 

 inspection. The following summer she sent me another lot 

 of them on deposit ; both of these have been in my possession 

 ever since, and have been repeatedly studied by me. I have 

 also examined the collection she sent to the Peabody Museum. 

 I should judge that I have thus had at least a hundred and fifty 

 of these pieces of quartz brought under my careful scrutiny. 

 Miss Babbitt had no knowledge of archaeology, and her fanci- 

 ful speculations in regard to the supposed use that had been, 

 or might have been, made of certain fragments, which she dig- 

 nified with the name of types, have tended to obscure the real 

 presence among them of some well-marked examples of palaeo- 

 lithic implements. I wrote her my opinion in regard to them, 

 and a portion of my letter was printed by her in connection 

 with her articles on "Vestiges of Glacial Man in Minnesota,'' 

 in the June and July numbers of the "American Xaturalist" 

 for 1884. In this I stated that " some of them I believe to be 

 implements ; many are only chips struck off in shaping imple- 

 ments, and refuse pieces left from such work ; many are natural 

 forms, and one or two rolled pebbles. ... I trace clearly upon 

 your implements such a preparation of them (i. e., by having 

 had most of their projections battered off by another stone) 

 for holding them in the hand. Many of yours bear evident 

 marks of use in the worn condition of portions of their edges 

 or of their points." All my subsequent study of them has 

 tended to confirm this opinion, and I can only repeat my 

 assured conviction that these rudely fashioned implements, and 

 the fragments that were found with them, whose edges are 

 still as sharp as when they were first struck off, are the " prod- 

 uct of an intentional breaking by the hand of man and not 

 the result of natural causes." 



It is important to notice that among the hundreds of 

 palaeolithic implements discovered by Dr. Abbott, at Trenton, 

 a few made of quartz are so absolutely similar to those found by 

 Miss Babbitt, and now either in my possession or at the Peabody 

 Museum, that it would be impossible to distinguish them apart.
