Extract

It requires but little imagination to conceive that a very slight subsidence of the country in North Wales lying between the Vale of Clwydd and the estuary of the River Dee would convert it into a peninsula consistingof Carboniferous rocks skirting to the north, and to the east a strip of Silurian ground. The backbone of this peninsula is composed of Lower Carboniferous rocks, forming the high range which starts from the bold cliffs that border the sandy flats of the north shore of Flint from Dyserth to Talacre. Stretching southwards by way of Halkyn Mountain, Moel Findeg, Nerquis Mountain to Minera and Llangollen, this range, in the main, forms ani anticline, off whose eastern flanks the higher divisions of the Carboniferous system dip in natural sequence towards the River Dee.

This paper was read at the Geological Society on April 4th, 1906. Subsequently the Publication Committee notified us, that unless we were prepared to omit all separate lists of fossils, and show their distribution in one large table at the end of the paper, they could not recommend the paper for publication. As the main object of the paper is to work out the palæoutological succession, and as we cstablish five life zones, we felt strongly that such a course was unfair to us as authors, that it would render the paper useless to those who went over the ground with it. We could not conceive a satisfactory table which would clearly indicate five zones from some hundreds of species collected from some sixty localities. As copious fossil lists had been published in very recent papers in the Quarterly Journal on Carboniferous zones in other localities, we demurred to the differential treatment and withdrew our paper under the conditions required. The paper is in the exact form in which it was read at the Geological Society, with the addition of a discussion on the horizon of the cherts, the interpolation being plainly indicated.
