"is in due between the red Storehouse and the" "red Devonian" of Peel. Probably as much as 1000 feet. If this observation is correct then the Silurian marine series has a thickness of not less than 4500 feet followed by about another 1000 feet of or more red Devonian beds. Over the Silurian and Devonian un- conformably lie the Zonne Brinksen series. It has been deformed since its deposition. The question will then be asked as to what is the age of the "Red Devonian". If it is unbroken with the Silurian it is either all Silurian, or to judge by the Garpe sequence it may go up into the Devonian quite high. At Arriway con- tinental conditions begin in late Storehouse time (may mean early Lelina time), while at Garpe it did not start until Middle Devonian time,
