Black band, 8 in. 



Bituminous coal, 3 ft. 



Bluish soft clay 1 ft. 



Shales and arenaceous fire-clays, (as ascertained by 

 boring,) the lower part black, terminating 1 in a hard 

 pyritii'erous stratum, 148| ft. 



Near the mouth of Six Mile Creek, in the township of New 

 Haven, numerous explorations have been made. A shaft sunk 

 at the mouth of the creek, furnished the following section, accord- 

 ing to information received from Mr. George Ott. The shaft 

 was sunk by Messrs. Silliman and Walker, 2"IJ feet, and the 

 section continued by boring: 



Superficial materials, 11 ft. 



Clay, bluish black, 9 ft. 



Calcareo-argillaceous black band 2 ft. 



Gannel coal, 2 ft. 



Clay and coal, 3J ft. 



Coal, 5 ft. 



Clay, light colored, 2J ft. 



Coal 2 ft. 



Clay, light colored 11 ft. 



Coal, 2 ft. 



Clay, light colored. 



A sandstone is seen in the vicinity, overlying the bluish black 

 shale. The black band outcrops in the "bed and bank of the 

 Shiawassee river at the bridge, and has been quarried for build- 

 ing purposes. Half a mile up the Creek it is seen presenting a 

 compact, fine-grained, calcareous character, of very black color, 

 and seems capable of taking a polish. According to the state- 

 ments given above, we have here 11 feet of coal within a verti- 

 cal -thickness of 18J ieet. The shafts which I have visited have 

 generally been found filled with water, so that it has been im- 

 possible forme to make personal observations. In such cases 

 I have deemed the statements of persons who watched the pro- 

 gress cf the work as better than an entire absence of informa- 

 tion At this place, as in most others, I had the opportunity to 

 inspect samples taken out. As to the nature of the strata, 

 therefore, I have judged for myself, while for their thickness, I 

 have had to depend upon others. If the information obtained
