Herschel’s before me, expressing his regret at being unable to attend on this occasion, but that his faith in the engine and its inventor remained unshaken. [42] Mr. Brunel’s estimate appears in the following letter to Mr. Warburton:— “_Feb. 28, 1831._ “DEAR SIR, “Having taken in consideration the erection of the proposed shops, the removal of the machinery, the accommodation for it, and also for the maker; having also taken into consideration the further completion of the drawings, and the ultimate accomplishment of the Engine until it is capable of producing plates for printing; though I feel confident that the sum of 8,000_l._ will be ample to realize the objects that are contemplated, I should nevertheless recommend that the Government be advised to provide for the sum of 12,000_l._ by way of estimate, and that the yearly sum required, exclusive of the sum requisite for the buildings and removal (say 2,000_l._), will not exceed from 2,000_l._ to 2,500_l._ “I am, &c. “M. I. BRUNEL.” “_Henry Warburton, Esq._” [43] This Mr. Clement had a legal right to do. Startling as it may appear to the unprofessional reader, it is nevertheless the fact, that engineers and mechanics possess the right of property to all tools that they have constructed, although the cost of construction has been defrayed by their employers. [44] Mr. Babbage informs me, that this letter was intended only as a private communication.
