Tennyson, right?
I come from haunts of coot and hern,
I make a sudden sally,
And sparkle out among the fern,
To bicker down a valley.
By thirty hills I hurry down,
Or slip between the ridges,
By twenty thorps, a little town,
And half a hundred bridges.
I would say from the context that it would be the sunlight on the dew on the ferns in the meadow. The fact that it follows the subject and verb "I make a sudden sally" it may refer to a dance movement that the speaker made.
