Elmwilliam August 16 1913 The quarry in the Whirlpool sandstone occur about five miles to the northwest of Georgetown. The Whirlpool sandstone is here about 12 feet thick. The lower 2 to 4 inches are red and mixed layer iron pyrite and from irregularities fitting into the Queenston shale. About 9 feet of the sandstone is regularly bedded and is the much softer after stone. As a rule the clay in grey but in places it becomes hotched with red or passes more en- tirely into a light red clay. The top 3 feet are much cross bedded and is thrown away. Over the sandstone follow the Cataract limestone that here are more sandy and shaly than at Cataract!
