"It appears as a very thin bedded (1/43") decidedly nodular limestone. Heavy throughout the bedding is irregular and locally very decidedly so. On flat exposures the beds are seen to seem in low domes but in section look cross bedded. Fossils chiefly trilobites occur at various levels but all are broken and are the same as those collected in M 2. Made no effort to get them today as it only again special petrifaction collection. Among good form incl nautiloid and the ventral valve of Camerota. Forrestell collected good material from the lower 30 feet of zone M 2. The great abundance of large depressed gastropods ceases on top M 1. Small specimens go on upward but the large Maclewares drop out. From our crowd today it is certain that the entire series of limestones so far seen are a conformable series. There is no marked or sudden change in the petrology and the fossils hold on from zone to zone especially above zone 8. The gastropods and the trilobites are the large dangers. Brachiopods are very scarce and byrgon almost absent. Cefalopods are rarely abundant but if we could get all the material seen then would be a few more forms than those we have.
