IS-Y-GARREG (IS-GAREG), a township, in the parish and hundred of MACHYNLLETH, county of MONTGOMERY, NORTH WALES, 2 miles (S. w.) from Machyn- Beth, containing 392 inhabitants. From this township many pleasing views of the river and vale of the Dovey, from Cemmes to its influx into Cardigan bay, are obtained; but other parts present lofty mountains and barren wastes, especially in that portion bordering on Cardiganshire. There are slate quarries and lead mines, but the latter are not now worked. Several respectable residences are scattered over the lower part of the township, which is bounded on the north by the Dovey, and on the west by the Llyvnant, rivers. A small detached portion of it is included within the new boundaries of the borough of Machynlleth. The poor are maintained by a separate assessment, the average annual expenditure amounting to £222. 17.
