It is natural for us moderns to conceive of the right to alienate as an inseparable incident of ownership, since we have known no other condition; and in the modern books and decisions the subject is generally disposed of with the curt statement as if it were a truism. It is believed that to such as are not familiar with the history of that doctrine a review of the struggle through centuries, by which it was finally established on its present firm foundation, would not be devoid of interest.
