seam having a thickness of two feet two inches, and the lower 

 of four feet two inches of good coal, while at Odin it is a solid 

 seam of nearly seven feet in thickness. 



The record of the Kinmundy shaft was very accurately kept 

 by the gentleman in charge of the work, and it is a very im- 

 portant one, as it gives more than two hundred feet of upper 

 coal measure strata not found at Odin or Sandoval. This is 

 in part due to the greater elevation of the surface at Kinmundy, 

 which according to the railroad level is 96 feet above Sandoval, 

 and in part to the absence of the heavy deposit of drift, which 

 was found both at Sandoval and Odin, and to the easterly dip 

 of the strata. 



The following is a slightly condensed copy of the record of 

 the Kinmundy shaft.
