Sometimes I feel a strange exhilaration up here which seems to come from something beyond the mere stimulus of flying.

I have noticed that music, like solid matter, is essentially crystalline in structure.

How rich are we that we can look on these worlds with the perspective of modern science ... that we do not have to wonder as did former men whether stars are jewels hanging from celestial drapery or peepholes in the astral skin of creation!

Can you imagine any better example of divine creative accomplishment that the consummate flying machine that is a bird? The skeleton, very flexible and strong, is also largely pneumatic - especially in the bigger birds. The beak, skull, feet, and all the other bones of a 25-pound pelican have been found to weigh but 23 ounces.
