Air Conditioning and Refrigeration

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.

My highway is unfeatured air,
My consorts are the sleepless stars,
And men my giant arms upbear—
My arms unstained and free from scars.
