Standing on the summit, one does not feel altogether comfortable when he looks down from the high side; but to crawl on your breast to the verge on the lower side and try to stretch your neck out far enough to see the base of the tower, makes your flesh creep, and convinces you for a single moment in spite of all your philosophy, that the building is falling. You handle yourself very carefully, all the time, under the silly impression that if it is not falling, your trifling weight will start it unless you are particular not to “bear down” on it.

In it hangs the lamp whose measured swing suggested to Galileo the pendulum. It looked an insignificant thing to have conferred upon the world of science and mechanics such a mighty extension of their dominions as it has.

It was like a long-drawn chord of a church organ, infinitely softened by
