These are all real close but no cigars... here are the words as I learned them:

Out on an Indian reservation
Far away from civilization
Where the foot of paleface seldom trod
White man went to fish one summer
Met an Indian maid, a hummer
Daughter of the big chief Spare The Rod

White man threw some loving glances
Took the maiden to war dances
Smoked the pipe of peace, took chances
Living in a tepee made of fur
Rode with her on an Indian pony
Gave her a diamond ring, a phony
And he sang these loving words to her

--chorus--
You are my pretty little Indian, oh Napinee
Won't you take a chance and marry me
Though daddy is the chief, 'tis my belief
To a very merry wedding he'll agree
It's true you're a dark little Indian maid
But I'll sunburn to a darker shade
I'll wear feathers on my head
Paint my face an Indian red
If you'll only be my Napinee

Sorry to say his con-talk caught her
Soon he married the big chief's daughter
Happiest couple that you ever saw
'Til his dream of love had faded
Napinee looked old and jaded
Just about like any other squaw

Soon papooses came in numbers
Red skin yells disturbed his slumbers
White man wonders at his blunders
Now the feathers droop upon his head
Too late now but still he's wishing
That he'd never gone a-fishing
Or had met that Indian maid and said

--repeat chorus--
