i mal tli u ' the principal Boam of 



y little diminished r riic most s tutherlv puinL at which 

 Coal has been found in place, is at EJaydi u's mine, where it was 

 .end in 1835, in digging the foundation of a mill. Tin's 

 is on section 1, in the township of Spring Arbor. The opening 

 occurs en San Istone creek where it is crossed by the highway, 

 on the | ion line running south through the S. E J. The 



outlier seems to be embraced in a gentle elevation, covering-, 

 perhaps, 40 acres to tl f the opening. Some distanco 



up the hill slope, a boring was made with the following rcBult: 



E. Drift materials, 8 ft. 



ilo, 22 ft. 



J, 4 ft. 



B Under clay, 14 ft, 



A. Parma ;-v.ndstone. 



In the drift which hns been carried into the hill the coal is 

 found only three feet thick, and contains a seam of Iron Pyrites 

 one foot from the top. Fragments of Black Band Iron Ore aro 

 brought out, which contain impressions of fishes. The sand- 

 stone (A) comes to the surface a few rods to the north, and a 

 boring tor coal was executed in it, of course without success. 

 The boring, however, became an Artesian well. 



One mile north of Ilayden's mine, occurs the Woodville mine, 

 owned by the Detroit and Jackson Coal and Mining Company. 

 We here find the coal measures overlain by a sandstone, which, 

 from its go< d exposure in the cut of the side track from the 

 mine to the Central Railroad, has been designated provisionally 

 the Woodville - e. The section passed in the shaft of
