the lagoon at 18 mile creek below the thin limestone band. On hill place this limestone is also present but there are several bands and with the intermediate shale probably 200 three feet thickly. Below the limestone occur the coral horizon which is about four feet thick. Here the corals are far more abundant and better preserved, the mass consisting of a Diphyphyllum coral species of Favosites some in very large masses, Michelinii, and hundreds of Heliphyllum Halli and varities. Brachiopods are scarce and those present are generally small specimens and single valves. Bryozoa are more abundant than at 18 mile creek. Mr. C. J. Hill (P.O. Ad. Le Roy) will gather corals for the museum at $5 per Hbl. or at the rate 12 1/2 c per hour. I asked him to put up from me one or two Hbs.
