“ The farther we look back into history, the longer we find the intervals between the permanent improvements of culture. The present age is resplendent not less for the magnitude of its inventions and discoveries than for the speed with which they have crowded upon one another's heels, and have been carried round the world. No previous time has approached ours in its achievements, and, if ever any force of culture deserved apotheosis, it is steam. ”
