to finish the old Difference Engine on its original plan than to construct a new Difference Engine with the simplified elements devised for the Analytical Engine.
It then proceeded to state that—
"The fact of a new superseding an old machine, in a very few years, is one of constant occurrence in our manufactories; and instances might be pointed out in which the advance of invention has been so rapid, and the demand for machinery so great, that half-finished machines have been thrown aside as useless before their completion.
"It is now nearly fourteen years since I undertook for the Government to superintend the making of the Difference Engine. During nearly four years its construction has been absolutely stopped, and, instead of being employed in overcoming the physical impediments, I have been harassed by what may be called the moral difficulties of the question. It is painful to reflect that, in the time so employed, the first Difference Engine might, under more favourable circumstances, have been completed.
"In making this Report, I wish distinctly to state, that I do not entertain the slightest doubt of the success of the Difference Engine; nor do I intend it as any application to finish the one or to construct the other; but I make it from a conviction that the information it contains ought to be communicated to those who must decide the question relative to the Difference Engine."
The reference to the Royal Society, proposed by the Chancellor of the Exchequer, in his letter of the 14th of January, 1836,[1] did not take place; and during more than a year and a half no further measures appear to have been adopted by the Government respecting the Engine.
It was obviously of the greatest importance to Mr. Babbage that a final decision should be made by the Government. When he undertook to superintend the construction of the Difference Engine for the Government, it was, of course, understood that he would not leave it unfinished. He had now been engaged fourteen years upon an object which he
