one of the series, characteristic examples are drilling a reef from 6 inches to 2 feet thick. The lead lay in the position north and also tumbled about, giving the true thickness less than a reef. A perfect hipster or sand horizon concretions, crystallal matter, and flat teeth of chalks. Some are horizons that are not, but Ransom says these can be had by heating the wall as he may form silicified. Later he got silicified ore in Feb 15-1926. The Permophrenia is dry thick, but if any pathy late and later too much tiny or more, and at lower levels Beyond lay the Conachian series with the same general structure and dips. Dale measured about 16,000 feet for but evidently the series replaced itself so that the true thickness may be about 5,000 feet. Allen told me he saw many 'oyster like shells'. Can there be Brachiopods?
