Mr George Maw, in the Geological Magazine, Vol. IV. pp. 24 and 299, has described a number of sections in Flintshire and Denbighshire in which white clay or sand occurs under Boulder-clay. A newly-exposed section near Colomendey Hall, about three miles from Mold, is very important on account of the complete series of glacial drifts by which the white clay is overlain. I lately examined it in company with Mr. Manning, of the Chester Natural Science Society.
page 67 note 1 Nearly all that can be seen of the blue clay fills up a hollow in the white clay. But a bore-hole at some distance from the pit reveals its existence in the same position relatively to the other deposits.
