An argument drawn from inconvenience is of the greatest weight [is forcible] in law. Co. Litt. 66a, 97a, 1526, 25S6; Broom, Max. 184. If there be in any deed or instrument equivocal expressions, and great inconvenience must necessarily follow from one construction , it is strong to show that such construction is not according to the true intention of the grantor; but where there is no equivocal expression in the instrument, and the words used admit only of one meaning, arguments of inconvenience prove only want of foresight in the grantor. 3 Madd. 540; 7 Taunt. 496.
