his employers (one of which, on the Nittany Valley ores, a model of 

 geological work, has been published), but most of which are in the 

 archives of his employers — his numerous publications in the Pro- 

 ceedings of our Society, his general repute as to familiarity with 

 the geology of the State, combined to make him the choice for 

 State Geologist under the act of 1874. 



He was Librarian of this Society part of the time and Secretary 

 all the time from 1858 to 1887. 



He was Vice-President from 1887 to 1898. 



My personal intercourse with Prof. Lesley began with the organ- 

 ization of the Second Geological Survey in 1874. 



Since that time he as State Geologist and I as Secretary have been 

 in the most intimate connection. 



In that period of over twenty years I have been impressed with 

 his unselfish motives, supervising the field work of his assistants 

 with the sole idea, (i) of the good of the Survey, and (2) that every 

 man should receive full credit for his work. 



He is a thorough, unselfish, impartial man of science. 



It is largely due to Prof Lesley, in continuing across this State the 

 work begun by Prof Cook in New Jersey on the terminal glacial 

 moraine, that the wonderful recent revival of interest in surface 

 geology is due. The modern geology which attempts to account for 

 the present condition of the earth's surface may almost be said to 

 date from the survey of the terminal moraine. 



Aside from geology. Prof. Lesley, in his Lowell lectures, delivered 

 in 1865-1866, on the ''Origin and Destiny of Man," branches far 

 afield into Egyptology and Theology. In these subjects, which he 

 merely touches, he shows the hand of a master. 



A list, possibly imperfect, kindly prepared for me by Miss Mor- 

 rison, is hereto appended of Prof Lesley's contributions to our 

 Proceedings. The titles number sixty-nine, on almost every sub- 

 ject conceivable. But besides these printed papers, he has often 

 delighted the Society with impromptu remarks on matters pending. 

 We all remember how brilliant these impromptu remarks were ; how 

 he illuminated what was obscure and explained what was confused. 

 Sad to say, no record of these speeches has been preserved. 



In the preparation of this brief and inadequate sketch, it has been 

 my duty and pleasure to read again some of Prof. Lesley's publica- 

 tions, and I have been impressed more than ever with his amazing 

 versatility, with the power of his imagination, illuminating every
