"THE SONG OF KAA
"Beat with thy club on a hollow tree
While I chant the song of Kaa for thee:
I lived in a cave, alone, at first,
Till into a neighbouring valley I burst
Wild and bearded and seeking prey,
And I came on Naa, and bore her away ...
Away to my hole in the crest of the hill,
Where I broke her body to my fierce will....
