Seam No. 3 is the third seam from the bottom. A side entry had been driven in on the coal for 60 feet, but water now barred the entrance and prevented a thorough scrutiny of the seam. Its thickness was about 3 feet 6 inches, of which there was a band of lignitic coal of three-quarters of an inch near the top, and five inches of the same near the bottom. The weathered outcrop of this, as of the coal-beds of Washington Territory generally, had a brownish hue, but the fresh surfaces showed a good black bituminous coal. It lies firm and regular in its bed. When dug and handled, it goes to small pieces, and may generally be crushed to powder in the hand; which, of itself, is no bad sign of a good coking coal. Seam No. 4, the second seam from the bottom, descending: FT. INS. Roof, Slate 2 0 Bone 2 0 Coal 0 6 Fine-grained Sandstone, average 2 2 Natural Coke 0 6 Bituminous Shale 0 6 Coal 4 2 Bottom, Sandstone. The coal of this seam is soft, black and lustrous. An entry was driven in 50 feet, which required much propping, the roof being bad. At the end of this distance we came squarely against a wall of sandstone, showing a fault. At this point six inches of the top coal is thrown up vertically, which showed that the seam thus far had dropped, and that the continuation was to be looked for at a higher level. Mining upward through the soft material, the coal had been again struck at an elevation of 16 feet, but not the full thickness of the seam, and not in its true position; but after following it upward 4 feet more the seam was found in its natural state. There seems to be no slate in this seam, but occasionally there is found in it a ball of "nigger-head," or hard sulphurous matter, from the size of a man's head down. [Sidenote: Also good coking coal.] An experiment of coking this coal in a small pit at the mouth of this bank was made by Mr. Kirke and his coal-bank manager, with as satisfactory results as could be expected from so imperfect a trial. I found pieces of the coke lying near, and saw better samples which have been brought from here. While, of course, the coke thus made is not the best quality, it certainly promises well. [Sidenote: Large and valuable bed.] Seam No. 2, descending:
