Foley Abbott left the Pilgrim mine in Beaver Gulch, Idaho, the other day, to explore the steep mountain opposite, and came upon an opening in the side of the hill which he investigated. Making a torch of pine he went into the place, and after passing through a long narrow passage found himself in a large chamber with a smooth door perfectly dry and lighted by a brilliant flame in the center of the room. He approached the light cautiously and found to his unbounded amazement that the flame issued from the mouth of an image of a man made of what appeared to be silver, roughly formed. Mr. Abbot suspects that the workers of this crde sanctuary had discovered a gas jet in the rock and that there is communication down through the body of the rock through which the gas flows perpetually, indicating an abundant supply of petroleum under the mountain. There were a few heiroglyphs which Mr. Abbott could not decipher on the walls, and in one corner, a very large human skeletons with a stone tomohawk and mortar lying near.
