(Read 14th February 1829.) Few countries have afforded more delight to the traveller than Wales, which may, in a great measure, be ascribed to the imposing appearance of its romantic scenery. But though few pleasures certainly can be more gratifying than those that arise from the contemplation of a varied landscape, yet this country will be found to furnish materials for observation of a more useful and interesting kind. To the person who considers geology as connected with the improvements of agriculture, with the resources of a country, and with the changes which the earth's surface is made to undergo in the progress of the arts, this district will afford an ample field of instructive inquiry. As the whole of this country, however, would be too extensive a subject for a single paper, we propose confining our remarks to that district which is situate in the north-west corner of Wales, and which may be denominated the Snow don Range.
