Professor J. Peter Lesley', born in 

 Philadelphia. Pa., September 17, 1819, 

 died in ililton, JIass., June 1, 1903. 



After graduation at the Universitj' of 

 Pennsylvania in 1838, J. P. Lesley served

 Survey of Pennsylvania. In 18-10 he was

The abrupt ending of the survey in 1841 

 scattered the assistants, and Lesley went 

 to Princeton Seminary, where, to use his 

 own words, he 'indulged in the luxury of 

 a course in theologj-. ' But while studying 

 theology he had no opportunity to neglect 

 geology : his skill as a geological draughts- 

 man and his familiarity with the c(mdi- 

 tions in a great part of Pennsylvania made 

 him indispensable to Professor II. D. Rog- 

 ers, who was striving to secure publication 

 of the final report. Every hour which 

 could be spared during term time and the 

 whole of the vacations of 1842 and 1843 

 were devoted to preparation of the Penii-
