Could anyone tell me what does "spry" mean in Richard Garnett's poem
"Where corals lie", set to music by Elgar:
The deeps have music soft and low
When winds awake the airy spry,
It lures me, lures me on to go
And see the land where corals lie.
(...)
"Spry" seems here a noun, I think, not an adjective(=active, nimble).
Thanks for help.
