Limehouse, August 21-1912. Red. Left Collingwood at 6.30 A.M. and got to Georgetown at 10.05. It is raining as I leave Collingwood. No rain 30 miles to the southward. At Terra Cotta 5 1/2 miles to the north of Georgetown the top of the Georgetown is widely exposed. Here the brick-red shales are burnt for hill and drainage tiles. It's all red shales with an occasional green shale a few inches thick some of which appear to have very thin limestone nearbottoms and may hold fossils. One sees here at least 100 feet of these red shales. To the southward about one to 2 miles on the hill top about 100 feet over the railway is quarried the thin bedded "Clinton limestone". It's evident the Limehouse exposures, At Limehouse I saw that these few feet of them bedded li. are the introductory strata to the Shajana.
