How do I find the rhyming pattern in a poem?

Question:

How do I find the rhyming pattern in a poem?

I am trying to find a rhyming patter in the poem "Clancy of The Overflow", but I am not sure how to find it.

If it helps, here are two stanzas from the poem:

In my wild erratic fancy visions come to me of Clancy
Gone a-droving "down the Cooper" where the Western drovers go;
As the stock are slowly stringing, Clancy rides behind them singing,
For the drover's life has pleasures that the townsfolk never know.

And the bush hath friends to meet him, and their kindly voices greet him
In the murmur of the breezes and the river on its bars,
And he sees the vision splendid of the sunlit plains extended,
And at night the wondrous glory of the everlasting stars.

If you are able to help, thank you very much.

I agree to an extent with what someone else said; it's A-B-C-B, but lines 1 and 3, 5 and 7 have internal rhyme. So it is A-B-C-B but also look at "fancy" and "Clancy" (l. 1), "stringing" and "singing" (l. 3), "him" and "him" (l. 5), and "splendid" and "extended" (l. 7). The internal rhyme is just as important as the end rhyme.
