HEISKER, an isle, in the parish of North-Uist, county of Inverness; containing 39 inhabitants. It is one of the Hebrides, lying about two miles westward of North Uist; and is two miles in length, but very narrow. The soil is sandy, yielding very scanty pasture at any time, and but a small quantity of grain. The isle has hitherto derived its chief value from its kelp shores.
