The Promise of Air by Algernon Blackwood

It was a glad May morning, the air soft-flowing and cool, the sunshine warm and brilliant, when the youth cut his lectures and went out into the fields, drawn irresistibly by the electric rush and sparkle of the spring. The swallows were home from the Southern Tour, and the sky was singing. He could not sit and listen to chemical formulae in a lecture-room; it was not possible. He wandered out carelessly into the world of buttercups, following the stream where the feathered willows bent in a wave of falling green. It was a true bird-day, and his heart, uprising like the larks, was shrilling. He felt exactly like a bird himself, and it made him laugh as naturally as a bird might sing. He fell to copying their various cries. They came up close and saw him. They were aware of him. 'Birds of the sweet spring skies!'

he thought, and yearned to share their strange collective life, individual still, yet part of their magical community.
