AGISTMENT (from the old French gesir or gin, to lie ; see Edina. Rev., vol. cxxviii. p. 79), the profit arising front taking in cattle to lie and pasture in one's lands, applied more particularly, in the first instance, to the proceeds of pasturage in the king's forests. The tithe of agistment, or " tithe of cattle and other produce of grass lands," was formally abolished by the Act of Union, on a motion submitted with a view to defeat that measure. (See EdZn. Rev., vol. xxxiv. p. 73.)
