The survey as first organized had no immediate connection with 

 other institutions, although its director was at the time professor of 

 paleontology at Harvard University in Cambridge, Massachusetts, 

 and its chief chemist was professor of chemistry at the State agri- 

 cultural college at Lexington. An unofficial connection was made 

 with Harvard through the establishment by Professor Shaler of a 

 summer school of geology, the first sessions of which, through an in- 

 vitation by Governor Leslie, were held in Kentucky. Mr. John R. 

 Proctor, assistant on the survey, was employed by the university to 

 superintend the summer camp, the number of students in which was 

 limited to 30. The survey was put to no expense in connection with 

 the school, the advantage gained by the school being the permission 

 extended to the students of accompanying the parties in the field 

 to observe the method of work and, incidentally, to profit by the 

 knowledge of the assistants. In exchange for this the survey was 

 relieved of the expense of maintaining its own camp and of trans- 

 portation, and received the assistance of such members of the school 

 as were capable of doing useful work. Sessions of the school were 

 thus held during the seasons of 1875, 1876, 1878, and 1879. 



In April, 1880, Professor Shaler, through pressure of other duties, 

 was compelled to resign as director, and was succeeded by the former 

 assistant, John R. Proctor. The plan of procedure under Mr. Proc- 

 tor was outlined as follows :
