Onyx.

A vein of onyx was discovered in Garfield County, Washington, recently which the report of an expert mineralogist,who visited and examined the find, shows to be of considerable extent and probable value. The possible extent of the mines is 1,000 acres, and openings for a mile show a ten-foot vein. The people of the vicinity claim that their county is possessed of the only onyx mines in the United States.
