There is an extraordinary amount of supply as often can be picking in the sandstone of the Penns- ylvania, in fact very sometimes red is picked and green bedded. Sometimes the sandstone pre- dominate, and the [illegible] red shale, and then again two to an equal amount of both. The shales as a rule are one joint to brick, and it is rare to see green shales. At least one small green mass seen today in the Piston, and it had one species [illegible] more preserved and common. Nearly all the plant evidence is of Calamites and Cordaite leaves in the sandstone. When the Calcicke conglomerate are present there may be preserved an abundance of Cordaite wood. One fine trunk was seen in the Lismore tr. day near the Mallefark Salt Mine. Semi-circled and rain prints were not seen or at least rare, but much of my inspection was too dusty to note them.
