Oak Tree Swing

There's a swing that is hung from a long oaken tree, By a string where the young have a longing to be. Where they fly to the sky, ever higher they go, Till they cry, "Not so high! I shall die, don't you know?" And they tread through the wold all around by the tree, Where it's said ruins old can be found by a key. How they thought many-a night how this fact could be true, And they fought to set right while they wracked in a crew; But they never could figure that blur in the tale, So they clamber with vigor the fir by the trail. They'd retrace to the place where the moss covered tree Like a face, beamed with grace as it tossed o'er the lea. Such a hold that tree held on their glad little selves As they trolled songs of eld with the bad little elves; And the song that they sing is a song specked with tears, Of a long oaken swing cast along through the years; Left alone by the lane, overgrown, never seen, Ever blown by the rain, with a groan deep and keen, Till a small little girl stopped a while on her way, And a tall oaken burl with a smile bade her stay. How she clove in a dive through the grove, and the tree, How it throve, came alive in the cove, in the lea. {Comments and critique by those knowledgeable about consonance vastly appreciated.}
