of Burgess of Ohio, at the very base of this limestone is a fine shaly limestone cut containing Bryozoa of various genera, similar to the Waldron types. The dolomitic limestone is just by what I have called the Lewerville limestone else- where. 48 cont at the bridge east of Bardstown, the clay shale with Tetradium graduates down- ward into a harder gma, sive clay rock. The thick- ess of the sifter and is 3 ft 10 inches, and the harder rock below is 7 feet thick. The harder rock is the equivalent of the Waldin- sun rock. Similar hard clayey rocks occur at still lower levels 50 This is best seen 2 miles west of Bardstown, west of the bridge, where the total thickness of the Waldstein is seen to be about 11 feet. Including the rock beneath the thin shaly limestone, first below the Tetradium 15 horizon, the total thickness would be 15 feet. Immediately below this level are 23 feet of thin, very fossiliferous limestone, the Richmond limestone beds, cut carrying a great variety of fossils. From 13 feet down to 16 feet below the top of this Richmond series, colummaria is very com- mon, forming often large bundles. Beatricea occurs as- cordially. 6 feet are not exposed. The 6 feet below this are exposed in the creek bed, and con- sist of hard, blue, almost unfossiliferous, clay limestone.
