MACON COUNTY. 193 



In conclusion, I would say that for richness of soil Macon county will 

 favorably compare with any other county in this portion of the State. 



Note. — Since the foregoing" report was written a boring was made at 

 Decatur with a diamond drill, by the Western Coal Mining Company; 

 and I am indebted to Mr. Bean, their agent here, for the following- 

 record of the work. The boring stopped at the depth of 507 feet, 1 inch, 

 and in my opinion from S5 to 100 feet above the horizon of the Spring- 

 field and Howlett coal. The following is the record of this bore :
