The soil of your planet is dead, hard, stony and not capable of bringing forth anything without the light of the sun. The sun's soil on the other hand is soft and gentle, and not stony or sandy, as the softness of human flesh, or for still greater comprehension, it is as elastic as human flesh, or for still greater comprehension, it is elastic nearly throughout; so that none who happen to fall on the ground would suffer painful injury, the impact being as upon an air-cushion. It is not however of a tough elastic composure like your so-called rubber, but completely loose and not only elastic as a whole but in all its particles, which in themselves are globules filled with true life-ether. – The Natural Sun, Chapter 1, Paragraph 6
