... At Sagamore Hill, Theodore Roosevelt and I used to play a little game together. After an evening of talk, we would go out on the lawn and search the skies until we found the faint spot of light-mist beyond the lower left-hand corner of the Great Square of Pegasus. Then one or the other of us would recite: "That is the Spiral Galaxy in Andromeda. It is as large as our Milky Way. It is one of a hundred million galaxies. It consists of one billion suns, each larger than our sun."

Then Roosevelt would grin and say: "Now I think we are small enough! Let's go to bed."
