One-half milo east of tins, on tlio south tide of Iho river, a 

 hole was bon il with the result as follows:

Coal, 4 £ ft. 



Shale, . 11 ft. 



Sandstone continuing', 1 ft. 



The outcrop of these strata traced northward, would probably 

 6trike the bay shore in the vicinity of Sebewaing. 



From Barry, in Jackson county, around the northwest border 

 of the basin, the boundary is still less perfectly known. The 

 coal strata arc known to outcrop, however, on Sec. 22, in the 

 township of Benton, Eaton county, near the mouth of Grind- 

 stone Creek, and still again near the mouth of Co.il Creek, in 

 the same county. Indications al st of the neighborhood of 



an outcrop near the center of Ionia county; but beyond this no 

 authentic observations have been made. Coal is reported, how- 

 ever, to occur near the Big Rapids of the Muskegon, in Mecosta 

 county. As a white quartzose sand, suitable for glass, is stated 

 to occur .. Rapids, there is no improbability of tho 



approach of the coal basin to that vicinity, for there are no such 

 sandstones known except those which immediately overlie and 

 underlie the soal series. 



Numerous outcrops are known within the area marked out 

 above. In the township of Lock, Ingham county, the coal has 

 been taken from the bank of the Red Cedar river. This point 

 is nearly in the straight lino passing through Tusci la, Flushing 

 and .1 ibljr like these p i a position 



on the confines of the basin. Al the strike of the underlying 

 rock--. considerably toward the east, it is not 



unlikely that . torn boundary of tho coal basin will bo 



found pasting through Livingston county.
