"The viaduct at Canton, by the way, the bold conception and fine construction of which exited so much admiration in the minds of the excursionists, really was a most creditable piece of work. When they did build, they built better in those days than they now do, and the passage of forty years of constant use has developed no greater need for repairs on the Canton Viaduct that it has on the pyramids of Egypt."
