A North Wales inland county, surrounded by Merioneth, Cardigan, Radnor, Salop, and Denbigh; is chiefly a stretch of mountain pasture land, which rises to 2500 ft. at Plinlimmon, and in which the Severn rises; but in the E. are well wooded and fertile valleys. There are lead and zinc mines, and slate and limestone quarries. There is some flannel manufacture at Newtown. The county town is Montgomery.
