“ It is not merely a creation; it is a growth. It stands before us to-day as the sum and epitome of human knowledge; as the very heir of the ages; as the latest glory of centuries of patient observation, profound study, and accumulated skill, gained, step by step, in the never-ending struggle of man to subdue the forces of Nature to his control and use. In no previous period of the world's history could this bridge have been built. Within the last hundred years the greater part of the knowledge necessary for its erection has been gained. ”
