The agreement to prepare the volumes on the Minor Prophets for this series was entered into in 1890, - fourteen years ago. I did not then anticipate the serious obligations which were shortly to be assumed in other directions. But in all these years of administrative concern I have had recourse for change, comfort, and courage to my work on the Twelve Prophets. A large portion of the work had been finished as early as 1897, when the essential results on the structure of Amos appeared in The Biblical World.
