the same to the leading institutions of learning of Ohio. In their 

 estimate of expenses, the committee recommended an annual 

 appropriation of twelve thousand dollars ($12,000) for four 

 years as adequate to cover the work above outlined. The report 

 further recommended that for the prosecution of the survey there 

 should be appointed "a skilled geologist" with not more than 

 four assistants, one of whom was expected to be a naturalist. It 

 was also recommended that a topographical engineer should be 

 added to the corps. 



In pursuance of this action the Governor appointed Prof. 

 W.W. Mather principal geologist and Drs. S. P. Hildreth and John 

 Locke and Professors J. P. Kirtland and C. Briggs, Jr., as assistants, 

 and Col. Charles Whittlesey as topographical engineer. Professor 

 Mather was a graduate of West Point and was, at this time, engaged 

 in the geological survey of New York, having charge of the work 

 in the southeastern portion of that State, an experience which 

 brought him great prestige in Ohio. Dr. Hildreth was unable 

 to continue in the active work of the survey by reason of the infir- 

 mities of age, and retired, after a service of a few months, during 

 the summer of 1837. Col. J. W. Foster, of Zanesville, was added 

 to the corps during the first summer. Prof. J. P. Kirtland was 

 the naturalist of the survey, and it is safe to say no man in the State 

 was so well fitted for this place as he. Dr. John Locke, an Eng- 

 lishman by birth, and at the time professor of chemistry in one 

 of the medical colleges of Cincinnati, brought to the service of 

 the State good powers of observation and sound scientific train- 

 ing, though it does not appear that before this time he had 

 devoted special attention to geology proper. Col. Whittlesey 

 was, like Mather, a graduate of West Point, and had been con- 

 nected for a long time with the army. While in this service he 

 had had opportunity to make important geological explorations 

 around the south shores of Lake Superior. He was, in fact, one of 

 the first to report upon the mineral wealth of the now famous 

 districts of Marquette and Keweenaw Point. Professor Charles 

 Briggs, Jr., was a resident of Massachusetts, but had been 

 specially trained in the geology that was known at this time. He
