Spent Perdrie collection. Spent the afternoon at Cast Valley with Hartley. The Pentamenus occurs in the Cast Valley in two groves, one beneath the office garden bed and the other in the centre of it. About all that is exposed now is from a little below the Pentamenus bed into the second thicket from bed. Collected a few Lower Ordovany fossils for the Glenpaul Rock chart.
