Sep. 28 1900 Raining. Went the morning in broadm collections picking out the best Linn Seldersby and Christian fossils which he is donating to the National Museum to further the palaeontology of the Cumberland works. In the afternoon collected in the Lower Sils dints at Cark Valley. Here the section begins a little above the Rhynchonella former bed and i went upward through the second strata from bed. Above this the beds are covered but further above is an extreme upturn of deep seated cherty limestones which in more other than the Hesk flint limestone of the Lower District. I picked off these various years and found the thickness of the beds like about as at Lewis Boot Bank.
