PREFACE TO THE SECOm) EDITION. x iii 



little more than the statement that, with a limited amount 

 of time and labour, neither he nor his assistants had been 

 able to find any implements in undisturbed gravel in any 

 of these places; and the suggestion of various ways in 

 which he thinks it possible that the observers mentioned 

 may have been deceived as to the original position of the 

 implements found. But, as had been amply and repeat- 

 edly published,* Professor J. D. Whitney, Professor Lucien 

 Carr, Professor N. S. Shaler, Professor F. W. Putnam, of 

 Harvard University, besides Dr. C. C. Abbott, all expressly 

 and with minute detail describe finding implements in the 

 undisturbed gravel at Trenton, which no one denies to be 

 of glacial origin. In the face of such testimony, which 

 had been before the public and freely discussed for several 

 years, it is an arduous undertaking for Mr. Holmes to 

 claim that none of the implements have been found in 

 place, because he and his assistants (whose opportunities for 

 observation had scarcely been one twentieth part as great as 

 those of the others) failed to find any. To see how care- 

 fully the original observations were made, one has but to 

 read the reports to Professor Putnam which have from 

 time to time appeared in the Proceedings of the Peabody 

 Museum and of the Boston Society of Natural History,, 

 and which are partially summed up in the thirty-second 

 chapter of Dr. Abbott's volume on Primitive Industry. 



In the case of the discovery at Newcomerstown, Mr. 

 Holmes is peculiarly unfortunate in his efforts to present 

 the facts, since, in endeavouring to represent the conditions 

 under which the implement was found by Mr. Mills, he 

 has relied upon an imaginary drawing of his own, in which 

 an utterly impossible state of things is pictured. The 

 claim of Mr. Holmes in this case, as in the other, is that
