direction with nearly a vertical dip. A thirty-foot tunnel was di 

 into this seam some years atro. The coal was found to be good quality of 

 lignite, but the vein lining less than a foot in thickness, the work was aban- 

 doned. 



Another exposure in this field is near the Bogaehiel river, about right 

 miles southwest of Forks P. 0. Some years ago a company, said to be the 

 Narrow Gauge Railroad Company, drove a thirty-foot tunnel into the 

 exposed coal seam here. The coal was found to be a good quality of lignite, 

 but as the vein was less than a foot in thickness, the work was abandoned. 

 Below is an analysis of a specimen of coal from the headwaters of the Quil- 

 layute river, likely from the above tunnel: 1 



Moisture 5. 10 per cent. 



Volatile combustible matter 39 . 15 per cent. 



Fixed carbon 47 . 01 per cent. 



Ash 7 . 77 per cent. 



Sulphur 97 per cent. 



Total 100.00 per cent. 



TJu Fresl Water Bay Field. Drilling inland from the bay has exposed 

 several seams of coal, some of workable size. The coal is in the Oligoeene- 

 Mioeene formation. So far no development work has been done. Below 

 is a drill record from a hole in a deep gulch in a broad synclinal trough about 

 one mile south of the eastern end of Fresh Water Bay:
