Below the drift deposits a stream of sweet water was struck, 

 which rises in a constant flow to the surface. From the material 

 brought up by the sand pump, it is impossible to determine with 

 accuracy the thickness and quality of a coal seam, which is found in 

 connection with a coal-like slate rock, as in this boring. Mr. Ste- 

 phens, the owner of the place, after obtaining so favorable indica- 

 tions, determined to investigate the matter thoroughly by sinking 

 a shaft down to the coal beds, and I am informed that the work is 

 already in fair progress, which, if accomplished, will finally solve the 

 question as to whether valuable coal beds can be expected within 

 this district or not. It is to be hoped that of the 13 feet of black 

 deposits found in the boring, 7 feet may turn out to be good can- 

 nel coal, as the supposition is ; but even a somewhat thinner seam 

 would be a discovery of great importance for Saginaw district. 



At Standish, another boring for coal was in progress. When I 

 was there, it had reached the depth of 129 feet ; it went through

Subsequently, as I am informed, a thicker coal seam was met with 

 by a continuance of the boring. On Tittibawassee River, at Mr. 

 Shattuck's farm, 6 miles west of Saginaw City, explorations have 

 been in progress for several years back, by which the presence of
