July 23.
Went 4 miles easy of Derry, N.M. on a good road up to Flourite mines in Caballo Mtns. Mines called Nacky-A, owned by a Mr. Lucini.

About 1/2 mile E of mines and at base of hills in washes in the fan were seen some 20 - 30' of gray shale weathering red or yellow and abounding in fossils. Martinia is common but a large Atrypa was abundant below this. yellow shales contains large [[underlined]] Schizophoria [[/underlined]]. The fossils, except for Martinia, reminded me of the lower 25 - 30' of beds seen in Mud Springs Mtns.

At the mines, some Devonian shale was thrown out. This produced large Martinia and Atrypa but also Hypothyridina. The beds seem clearly to be Sly Gap.
