1834, for an interview with the Duke of Wellington, who, in reply, expressed his wish to receive a written communication on the subject. He accordingly addressed a statement to his Grace, pointing out the only plans which, in his opinion, could be pursued for terminating the questions relative to the Difference Engine; namely,
1st. The Government might desire Mr. Babbage to continue the construction of the Engine, in the hands of the person who has hitherto been employed in making it.
2ndly. The Government might wish to know whether any other person could be substituted for the Engineer at present employed to continue the construction;—a course which was possible.
3rdly. The Government might (although he did not presume that they would) substitute some person to superintend the completion of the Engine instead of Mr. Babbage himself.
4thly. The Government might be disposed to give up the undertaking entirely.
He also stated to the Duke of Wellington, the circumstances which had led him to the invention of a new Engine, of far more extensive powers of calculation; which he then observed did not supersede the former one, but added greatly to its utility.
At this period, the impediments relating to the Difference Engine had been partially and temporarily removed. The chief difficulty would have been either the formation of new arrangements with the Engineer, or the appointment of some other person to supply his place. This latter alternative, which was of great importance for economy as well as for its speedy completion, Mr. Babbage had carefully examined, and was then prepared to point out means for its accomplishment.
