Darius was clearly of the opinion
That the air is also man’s dominion,
And that, with paddle or fin or pinion,
We soon or late
Shall navigate
The azure, as now we sail the sea.

Air, air, fresh life-blood, thin and searching air,
The clear, dear breath of God that loveth us.

When I was born I drew in the common air, and fell upon the earth, which is of like nature, and the first voice which I uttered was crying, as all others do.
