in the commonest part. Crinoidal muds also occurs. In places there are sandy beds and these one apt to have fireclays. There is considerable mud - a fine mud - probably with the algae. Broadmouth tells me that the pebbles of the lower conglomerate are well rounded and flat rounded and that many of them have been split by frost action before deposition, In other words the pebbles were first rounded by stream action and then deposited on a bar where there were cold currents. The pebbles were then split and mud came at finally deposited. If this is true then must have been cold currents in any kind of time at least locally. There is nothing in the faunal evidence to go against this view. Of course it may be that the cold currents are restricted to drift lands and the cold evidence brought to the sea.
