No. 1 -vra,3 from section 7, Trimble township, Nob. 2 and 3 were from 

 the " Dugway," in Trimble, and No. 4 from Laurel Fork iii uuo jsame 

 township. 



Some of the ores are excellent. No. is quite rich in iron, with only 

 traces of sulphur and phosphorus. Taking the four analyses together it 

 will be seen that the average phosphoric acid is only 0.21 per cent., which 

 is quite low for Coal Measure ores. The average per centage of iron is 

 34.19. It is to be expected that the ores under impervious cover will be 

 carbonates exclusively, and, consequently, a little less rich in iron. 



There are several horizons of ore above that last given in the hills 

 bordering lower Sunday Creek, from which much ore could be obtained 

 were furnaces established in the vicinity to create a demand for it. In 

 some places there is an ore above the thin coal of the seam first above the 

 Bayley's Run seam. A sample of this ore, from the Moody land, in 

 Trimble township, was analyzed by Prof. Wormley:

The excessive quantity of silica forbids the usefulness of this ore.
