The changes in the methods of work between Canaletto's time and mine were never more clearly shown. When he drew the building being restored, it was hidden in scaffolding; when it was rebuilt, as I saw it, a few years ago, everything was done from the inside, till the top was reached, men and materials being carried up on elevators. It is said one of our ingenious American Captains of Labor offered to rebuild it free if the Venetians would let him put two elevators in, and have the profits of them for twenty-five years, after which he would hand it to the city and retire on the results. The Syndic declined, but put in the elevators.
