Stephen Johnson Field,
Farnsworth v. Minnesota and Pacific Railroad Company…
“ The estate of the company was, therefore, a purely 'executory inheritance.' Even if the rule could be held to apply to a grant by a State, its application is entirely superseded by the provisions of the constitutional amendment. They were designed to secure the completion of the road, or specified portions, within the time prescribed, by enabling the State, in case of default, to resume the franchises and lands pertaining to the uncompleted portion, or the whole if twenty miles had not been completed, and to seek other agencies or means for accomplishing the end in view. ”
