Wea. MON. FEB. 22, 1909 Ther. On the thin official maps there are three clay together. One is 10x10 far acres had trilobites in at least two places and probably many more places. One must find these pockets, and mainly near much calcite that appears to have left the less lime underlying diagenetic change. Clark found the first place a foot about from nick acorn and then Keith got me such place over 18 miles low. This I tried dug up and told not of it. That fair trilobites on with the ax, and become appear to be Paradoxides. Nor it will upset Keith's mapping. Probably having still been this fate. In the shales close by Charlie and me Berigle found three trilobites in the Highgate or adjacent shales. I have the two specimens. Another level is 10x10 far and here Charlie got over two trilobite payments that I have. Close by is a much larger level surrounded by shale. But not mine here. Close by these levels near shale outcrop the Berigle got a large boulder weighing 50 pounds with many trilobites. First any must.
