 acres. The proprietors aided to the extent of $200. 



2. A survey of South Mountain in sections 4, 7, and 18, in T. 46, 

 R. 29. Area, about COO acres. Owners contributed $200. A com-

 by the company's engineer during winter of 1869-70. 



8. The New England and Parsons mine and the opening made in 

 sec. 16, T. 47, R. 27, by the Lake Superior Iron Company were to be

 years previously, required limited resurveys. 



10. The Collins Iron Company's lot, SW. |, sec. 2, T. 47, R. 27, had

 the same condition. 



The above mines and properties were intended to be delineated 

 each on a separate map, and the whole work was now something 

 over half done. Major Brooks enumerated among those who had 

 rendered efficient aid Edward Breitung, D. G. Johnson, E. R. Liver- 

 more, and A. W. Maitland. 



In organizing for work in tlie Lower Peninsula [says the director's report for 

 1809] I nppointed as assistants, Profs. A. E. Dolbear and E. A. Strong. Pro- 

 fessor Strong de\otGd only some portion of tbe summer months to his work. 

 He made examinations and collected specimens in various paits of Kent and 

 Ottawa Counties. He submitted a report accompanied by a map, diagrams, and 

 a box of fossils. Professor Dolbear was to take charge of the field work in 

 the northern part of the I^ower Peninsula and contiguous shores of the Upper 

 Peninsula. Prof. N. H. Winchell and Prof. E. Haanel were added as amateur 

 assistants. With this party I proceeded to Traverse City on the 1st of July,
