February 15, 1869. 



Dr. Charles W. Stevens in the chair. 



Six members present. 



Dr. Stevens stated that the boring at the Artesian Well had 

 now reached the depth of 3,624 feet. 



He had compared the borings brought up by the pump with 

 some pulverized granite from the well-known granite quarries, 

 near the Iron Mountain, and to all appearance and under the 

 microscope the material appeared to be identical. He concluded, 

 therefore, that the boring had reached the primary rocks, and that 

 it would be useless to continue the work. 



On motion of Mr. Spencer Smith, a petition was directed to 

 be prepared to be sent to the Legislature of the State, now in 

 session, asking for the completion of the State Geological Survey.
