W. II. WEED TWO MONTANA COAL FIELDS. 



The coking coal is separated in mining and sold separately for Mack- 

 smiths' use. The second parting is not separated. 



Examinations of the coal bed, made at the various openings of the 

 Belt basin and other parts of the Great Falls field, show the following-

The Belt creek mines are now worked only for household fuels, but 

 their consolidation has already been effected and their further develop- 

 ment is likely to be accomplished in the near future, now that railroad 

 facilities are afforded by the Neihart road. 



The coal seam thins rapidly north and south of Belt. On the north il 

 is but 2 feet thick some two miles below Belt, and thins out near the 

 mouth of Little Belt creek, where the coal dips beneath the creek bed. 

 Toward the south the seam thins out and deteriorates in quality toward 

 Otter creek, and although it lias been found on Otter creek and opened 

 near Mann post-office (Otter), the seam is but ■'>'■ feet thick, the bottom 

 bench only being workable.
