Our scientists who have sneered at the possibility of life on Mars, because of its rare atmosphere, have overlooked the simplicity of the problem. They delight in propounding posers for Omnipotence. If a Creator dilutes oxygen with three parts of nitrogen on one planet where conditions make a dense atmosphere, why should He not dilute oxygen with an equal part of nitrogen on a planet where the air is rare? Air is not a chemical compound, but a simple mixture. When a stronger, more life-giving atmosphere is needed, let there be less of the diluting gas. The nitrogen is of no known use, except to weaken the oxygen.

I am tired of this bird-cage.

Put on the diver's suit and helmet, and I will weaken the pressure of the air gradually, to prevent bleeding at the nose and ears which a sudden change might cause. When you are used to the low pressure, you can throw off the helmet and try the Martian double-oxygenated air.
