There is but little doubt,however, that ultimately this coal will be extensively used. When theNorthern Pacific Railroad is built through this region the utility of thecoal-beds near Fort Ellis will become more and more apparent. I have made the following analysis of the coal. No. 1 is a poor speci-men, No. 2 medium, and No. 3 the best. The coal is black, (brown inpowder,) has a high luster, irregular fracture, specific gravity. is moderately good, and has a high luster: Analysis Ko. 1. Per cent.
