The forest I met shook/swayed

Voice of the THIRD SPIRIT
In the blue depth of the waters,
Where the wave hath no strife,
Where the wind is a stir,
And the sea-snake hath life,
Where the Mermaid is decking 
Her green hair with shells;
Like the storm on the surface
Came the sound of thy spells;
O'er my calm Hall of Coral
The deep echo roll'd--
To the Spirit of Ocean
Thy wishes unfold!

FOURTH SPIRIT
Where the slumbering earthquake
Lies prone on fire,
And the lakes of bitumen 
Rise b______ higher;
Where the roots of the Andes
Strike deep in the earth,
As their summits to heaven
Shoot soaringly forth;
I have quitted my birth-place,
Thy bidding to bide--
Thy spell hath subdued me,
Thy will be my guide!

FIFTH SPIRIT
I am the Rider of the wind, 
The Stirrer of the storm;
The hurricane I left behind
Is yet with lightning warm;
To speed to thee, o'er shore and sea
I swept upon the blast:
The fury/flake/flow I met s______ well, and yet
'Twill shine/swirl ere night be past.

And the sea-snake hath life,

Her green hair with shells;

Came the sound of thy spells;
O'er my calm Hall of Coral
The deep echo roll'd--
To the Spirit of Ocean
Thy wishes unfold!

Almost, but you have to use a form that makes sense here ('"pillow" fits the blank in the hint, not quite the blank in the line).

Unless by "make sense" you meant something that fit logically in the context or that was in line with what the author meant, but grammatically it seems fine to me, but I may be missing something.

And pillowing probably doesn't scan.
