Abstract
OUR knowledge of the geology of England is enriched by Dr. J. E. Marr's conception (The Naturalist, February, 1921) of Yorkshire as an earth-block surrounded by down-folded strata, but with its own Carboniferous series little disturbed, owing to the rigidity of a pre-Cambrian mass beneath. The block, which became tilted somewhat to the east, has had an important effect on the drainage, and even on the progress of ice-sheets, in northern England.
